Villari develops wireless sensors to monitor aging infrastructure

Aging infrastructure is a growing concern for authorities across Europe, requiring them to look for more innovative monitoring tools as time goes by. Moving steel structures, in particular, ask for regular inspections and, increasingly so, maintenance. Monitoring those manually can be a challenge, so Olivier Baas and Hugo Romer, co-founders of Villari, took it upon themselves to create a solution that automates at least part of the process. 


Villari’s mission is rather straightforward – develop sensors and wireless monitoring systems that provide users with a 24/7 view of their assets and notify them of any possible structural problems.

“We build sensor systems that are able to monitor steel structures,” Olivier says. “If you have a steel structure that moves even a little bit – a bridge, ship, or an offshore platform, at one point it starts to crack and it becomes a problem. We can apply our systems to critical locations on such structures and monitor their state.” 

As a result, operators gain a clear overview and insights into the state of their structures and are able to easily plan (and foresee) maintenance work. 

Olivier and Hugo’s entrepreneurial journey started in late 2018 and goes back to their days at the TU Delft. They both did Offshore Engineering as a Master’s degree and graduated under the same professor. It was their professor, in fact, who had come up with the idea for the wireless monitoring sensors and as soon as all the academic research around it was finished, Olivier thought it might be a good idea to try and turn it into a business. 

He reached out to Hugo, who was then in China for work, and the two quickly agreed to do this together. “I called Hugo and he immediately said we should do it. He just needed a bit of time to figure a few things out first,” Olivier says. “Of the two of us, Hugo has always been the one to think things through. I usually tend to dive in headfirst,” he laughs and Hugo agrees with a nod. 

So, in early 2019 and with Hugo back from his project abroad, the two started thinking on how to turn an idea into a business success. 


With both of them coming from a technical background, Olivier and Hugo were looking to learn more about what it’s like to run a company. In May 2019, they joined the YES!Delft Validation Lab and it all started rolling from there. 

“The Validation Lab was a real pressure-cooker,” Hugo remembers. “It’s a ten-week program of identifying your potential clients and finding your product-market fit. We went in Olivier’s little car, driving around and doing interviews all around the Netherlands. It was intense but it was a great way to validate the potential of our idea.” 

They often had as many as six interviews in a day, which left them with a lot of information to process day in and day out. Soon after finishing the Validation Lab, the two co-founders applied and were accepted into the YES!Delft Accelerator Program, which has helped them gain valuable connections and introduce their technology to the market. 


If they need to point out one challenge that they have struggled with along the way, Olivier and Hugo would have to say it was the decision which market segment to focus on. They have come to learn that there are simply a lot of applications for their solution. For a startup, that is a good problem to have but it can also make it difficult to stay on track. 

“For now, we’ve decided to focus on bridges,” Olivier says. “They are easily accessible – especially compared to offshore platforms, have a lot of cracks, and need constant monitoring.” It is a good market for them to enter and test their solution in.  

“Most of our (potential) clients there are public companies and with our sensors, we are looking to make their work more time- and cost-efficient.” 

The startup is currently working with Rijkswaterstaat and is setting up more pilot projects. Expanding their portfolio is essentially what they want to achieve in the months to come. “By the end of the year, we will have a second prototype of our wireless sensor,” Hugo says. “We want to set up 4-5 new pilot projects next year with different clients and convert those into commercial projects. We are looking forward to getting our first bit of revenue with our technology.”

Olivier and Hugo have set themselves clear goals for 2021 and they seem to be on the right track to reach them. They’ve found their product-market fit and are ready to roll up their sleeves and go further into the market.

Gradyent and YES!Funded: The importance of getting the rights funds at the right time

A good click is key to every startup-advisor relationship out there. In their early days, in particular, startups need specialized support to steer their business in the right direction and they need the right advisor to help them do that. This is exactly the case with Gradyent, a startup developing an artificial intelligence (AI) cloud platform for making district heating networks more efficient, and YES!Funded, a service launched by YES!Delft to support startups getting funds. 

From 0 to 2 funding rounds in just over a year

A lot of startups tend to take their time in validating their idea, finding their product-market fit and signing their first customer. Gradyent is not one of those startups. On the contrary, they hit the ground running.  

It was early 2019 when four serial entrepreneurs – Hervé Huisman, Robert Vrancken, Freek Smelt and Pieter Broekema – got together to found an innovative company that would tackle the inefficiencies that district energy networks often struggle with. With their combined experience in building successful businesses and scaling analytics technologies in the energy industry, this new venture was just the right fit for them. 

“We started out knowing that there is a problem to solve when it comes to making district heating networks more efficient,” says Hervé. “Many of them have old and even outdated control systems, which has them lagging behind in terms of digitization.” The solution they had in mind was an AI platform in the cloud that can help network owners reduce energy losses and improve efficiency. 

It was the start of Gradyent.

Winning their first customer soon after they launched the company was proof of the potential of their solution. Yet, as with any young company looking to grow fast, potential and an initial success weren’t going to be enough. They needed extra funds. Knowing this, the team reached out to YES!Funded to help them find the right financing tools and connections, and grow even further from there. 

“We started YES!Funded about a year ago because we found out that startups don’t have much knowledge on how to structure their company or make it financially viable,” says Jan Geert van Hall, Investment Director at YES!Delft. “When it comes to raising their first rounds of funding, they often don’t even know where to start.” 

With the help of YES!Funded, this is no longer a problem. In only a few months of working alongside Jan Geert, Hervé and the team of Gradyent had their first round of financing in the bag. It came from henQ, a venture capital (VC) firm supporting B2B software startups.

“It was a small first round, but it helped us accelerate our product development, connect new customers and gain traction,” says Hervé. It was a stepping stone towards increasing their valuation and going for a much more prominent second round later on. 

Needless to say, the team didn’t sit around waiting for that second round to come. They rolled up their sleeves and spoke to more than 20 potential investors in just a few months. With the help of Jan Geert, his network and financial expertise, they identified the most suitable candidates and eventually signed with three European investors for the sum of 1.9 million euros. Those include Dutch energy innovation fund ENERGIIQ, and VCs Capricorn Venture Partners from Belgium and Helen Ventures from Finland. 

Addressing the right opportunities at the right time

Gradyent secured their second round of funding in June 2020 and are already using it to further develop their AI solution and expand their network beyond the Netherlands. 

“We are happy to have these three investors onboard, as each of them brings something valuable and different to the table,” says Hervé. “Capricorn is an experienced VC fund with a strong track record, which adds credibility to our company. ENERGIIQ brings us their regional network in South Holland and expertise in the field, with Helen Ventures providing us with an opportunity to enter the Scandinavian market, which is the most advanced district heating market globally.”  

It all sounds like Gradyent have found the right partners at just the right time. Yet, that doesn’t mean their journey hasn’t had its ups and downs.

About a year ago, without yet the support of Jan Geert, Hervé and the team took it upon themselves to manage their fundraising. One of their first moves was to approach UNIIQ, the proof-of-concept fund of Innovation Quarter (IQ), focusing on early-stage innovative companies from the West Holland region. Although they were a great match, what the team didn’t realize is that they already had too much traction for what the fund was looking for. 

Timing, they learned, is everything.

“From experience we know that the most challenging period for a startup is finding their first investor and getting the deal done,” says Jan Geert. “For each step of your customer traction or product development, you need to have a funding plan. In each step, the opportunities will be different and perhaps even diverse.” 

Both Hervé and Jan Geert agree that not approaching UNIIQ on time was a missed opportunity. Yet, the strong team and business proposition of Gradyent made an impression and they were soon in negotiations with ENERGIIQ, another fund of IQ. With Jan Geert’s timely advice, they were soon able to seal the deal. 

“It is crucial for startups to use the right instruments of financing,” Jan Geert continues. “The bad news is VCs don’t often look at early-stage companies. The good news, though, is that there is a wide range of other instruments that you can combine to get to the target of your round.” 

Jan Geert is the person with the overview of those instruments and the knowledge of when to use which one. In fact, advising Gradyent on the timing for each investment round and approaching the right funds or VCs has been one of Jan Geert’s main contributions to the success of the team so far. He has supported them on a strategic as well as a more practical level by introducing them to investors, steering the due diligence procedures and establishing necessary shareholder agreements. 

In essence, he has helped create a structure that Hervé and his team can follow each time they go for a next investment. “Securing our first round of funding was complicated because there was no foundation for us to step on,” says Hervé. “The second one was a whole different story and that is largely because of the support of YES!Funded.” 

With a committed team, a strong advisor and the right approach, Gradyent is well on its way to success. Their next big milestone may be just around the corner.

Noise pollution

Delft startup DeNoize on its way to tackle noise pollution

Noise pollution is nothing new to people living and working in big cities, yet what many may not be aware of is that it is also a major health risk. Delft-based startup DeNoize knows all about it and has made it its mission to tackle the challenges of noise pollution and enable a healthier living environment. How? By installing its active noise cancellation technology – similar to that in noise-cancelling headphones – into the frame of windows, drowning out the noise of the busy streets underneath and the large planes flying overhead.


During his studies, Aman was looking into how to design airplanes to be less noisy and more efficient, and had a strong interest in mitigating aviation noise. “There is a lot of potential in finding a way to make airplanes less noisy,” says Aman, “but if I were to turn that into an impactful solution business, it would have taken years and years.”

Instead, he wanted to create something here and now, so he focused on putting a new spin to his research and findings. “I started looking at the problem from a different angle and decided to tackle noise issues on the receiver’s end instead of its source,” says Aman. He joined the incubator program of Deep Science Ventures, a six-month pressure cooker for entrepreneurs who want to solve key societal problems, to help him kickstart his venture.

“That’s where the whole idea came together. I decided to develop a solution that can be integrated into the facade of a building and isolate it from the outdoor noise.” In a nutshell, he made a plan to create a new generation of smart windows.

With active noise cancellation at the heart of it, a very specific type of technology in itself, Aman saw the need to look for a co-founder. He found that co-founder in the face of Olivier Schevin, a fellow entrepreneur based in France, with years of experience in exactly this field.


With the Deep Science Ventures program behind him and a round of financing that he got at the end of it, Aman moved back to the Netherlands to continue working on the DeNoize technology. In December 2018, he and Olivier got accepted into YES!Delft’s Accelerator Program, which gave them the know-how and network they needed to take the startup to the next phase.

“YES!Delft is a specialized incubator that gave us the stamp of approval we needed in the market,” Aman says. “When we joined, we were also paired with a mentor, who has quite some experience in the glass industry, and that has been of great value to us.”

The community of startups that YES!Delft has built over the years has also proven to be beneficial to Aman and DeNoize.

“There are startups in different stages of their development so there is always someone who has been in your shoes and can advise you when you’re facing a challenge. Physee, for example, is working in the same market as us and it is always good to spar with them,” Aman adds.


Today, in only two years’ time, DeNoize has grown from one man with an innovative idea to a team of over 20. Olivier is still based in France, with four students and an intern working alongside him. In the Netherlands, the startup has two full-time employees and three groups of students working on various design projects for it.

So far, the technology is in the prototyping stage and on its way to being converted into a product. “We’re working together with a glass manufacturer to make sure that our technology can fit into their products,” says Aman. “And based on recent tests, it looks good.”

While glass manufacturers could be a key customer segment for DeNoize, at this point they see them as their closest partners – working together on prototyping and knowledge-sharing. The product that will eventually be integrated in the frames of windows is planned to be ready within a year from now.

Keeping them going until then are several financing opportunities that the team has secured, including a loan from Rabobank, a round of funding from UNIIQ and grants from the government.

Perhaps one of the most notable achievements of the team so far is their collaboration with the Royal Schiphol Group, which they announced recently. The agreement between the two companies is for studying the effects of noise pollution on people who live in close proximity to Amsterdam’s Schiphol airport.

The research is planned to start in October 2020 for a duration of one month. The goal will be to understand the effects of noise on residents’ well-being and investigate how DeNoize can play a role in improving the quality of life of those living close to major noise sources like airports, highways, and train stations.

“We are doing research on people’s perception of noise with regard to their comfort, stress levels and mood. We then want to simulate how our technology can improve their acoustic environment,” Aman says.

While the technology is not market-ready yet, Aman and his team are already talking to potential customers to make sure they have them lined up when the time comes. DeNoize is mostly focusing on real estate developers such as Schiphol Real Estate and Heijmans, who can increase the value of their buildings by integrating the startup’s noise cancelling technology.

From this point on, DeNoize will be focusing on putting their technology on the market and getting the right partners and customers onboard. Working together with a partner like Schiphol Group is sure to boost the startup on its way to success.

Blue Sparrows: The medtech investment fund made by entrepreneurs for entrepreneurs

Incubators and communities like YES!Delft are there to offer startups the support and know-how they need to start their innovative businesses and grow. They introduce them to a network of fellow innovators that they can draw resources and inspiration from. And every so often, that network yields some pretty interesting collaborations. This time focused on medtech

Bo Wiesman is a seasoned entrepreneur and the CEO of NewCompliance, an innovative company that offers predictive dashboarding and analytics solutions to hospitals. As of a few years ago, he is also the co-founder of Blue Sparrows, an investment fund for early-stage medtech companies.

Bo started Blue Sparrows together with six fellow medtech entrepreneurs and as a group, they are an example of what networking at YES!Delft can lead to. 

“We are all entrepreneurs from YES!Delft and this is where it all started back in 2014,” says Bo. “Because we were such a strong group of entrepreneurs, we got many requests from other medtech founders to provide advice or coaching, so we came up with the idea of setting up our own investment fund.” 

It took Bo and the rest of the team about four years to set the fund up and get it to do what it was meant to do – invest in high-potential medtech companies from across the country. Today, it also has two experienced fund managers onboard, whose expertise complements the entrepreneurial experience of the rest of the team.

An investment fund run by entrepreneurs

What makes Blue Sparrows different from other funds is that while it does have people with an investment background onboard, it is first of all run by entrepreneurs. 

Having built – and some even sold – their own business in the medtech sector, Bo and the rest of the team know what it takes to create a company from scratch. They have been through the ups and downs of being an early-stage company and can guide current startups to success, while avoiding the mistakes that they had once made. 

“We can help startups on a very operational level – from validating their idea or already existing product, to creating a business model that works, to clinical validation and medical certification,” says Bo. As a team, they believe that adding actionable knowledge and experience to a company early on can significantly increase their chance of success. They also look beyond the financials and at the potential that a startup holds. 

“We are entrepreneurs and not fund managers, so we can determine from our own experience whether a specific proposition has the potential to be successful. And because we are entrepreneurs, we can determine that way more clearly than fund managers can. They look mainly at the financial aspects, while we look at the product, the business model and the team – and help make adjustments where necessary.” 

Focusing on early-stage medtech startups – a conscious choice

A lot of people might think that investing in an early-stage, innovative company is risky business. And they wouldn’t be wrong. Yet, for Bo and the rest of Blue Sparrows, it was very clear why they should focus on that specific group. Making one wrong step early on in a business can be detrimental, so getting the right knowledge and advice at the right time is crucial. The team of Blue Sparrows is, therefore, of the opinion that they should only invest in companies that they can add real value to. 

“We tend to invest in the areas that we know extremely well, and that is medical technology,” says Bo. “It is not only about the money we invest, but also about the knowledge and coaching we can offer. That, too, has to be on a high level.” 

To date, they have made five investments in startups that they believe have the potential to develop a solution, which creates value for both patients and doctors. In the initial stage, Blue Sparrows invests typically between 200,000-250,000 euros per startup, and mentorship and coaching come as part of the package. The fund subsequently continues to invest as the company grows and achieves new milestones.

One of their most recent and also successful investments has been in a startup called UV Smart, which has developed an innovative solution based on UV light that helps disinfect medical instruments and devices within seconds. “We invested in UV Smart about 18 months ago, as we recognized that they have a great team and an advanced technology,” says Bo. 

As with all medical technologies, though, certification takes a long time and first revenues do not come in overnight. The current COVID-19 situation, however, has created an urgency for a solution like the one of UV Smart. “Normally they wouldn’t be selling yet, but due to the circumstances, they have had  their product medically certified last  month,” adds Bo, whose team has been advising the startup in the process. 

It is surely of great value for a young medtech company to have experienced advisors – with the right business and industry knowledge – supporting them. Especially in times of uncertainty. 

Blue Sparrows have found just the right niche to focus on. From here on out, they are looking to add new companies to their portfolio and later raise a second fund to continue investing in early-stage medtech startups. In the end, the only way to add value to the sector is to keep supporting its rising stars. 

Urbandine: The hospitality solution for the 1.5-meter economy

The hospitality industry has taken a hit over the past months, with the COVID-19 outbreak keeping restaurants, bars and cafes closed. Opening up again, while impatiently awaited, may turn out to be a slow start for many of those businesses. Urbandine, a YES!Delft startup, has developed an intelligent mobile ordering and payment platform that allows customers to order and pay directly through their smartphone. This is hospitality solution that can make work at 1.5m distance that much easier. 


Urbandine is the brainchild of Jaikishen Jayesingha, Jay for short, and Bhagya Goonewardhane, two friends who first met in high school in Sri Lanka. While they have known each other for over 13 years, they have not walked the same paths. After high school, they each pursued their own interests – Jay went to the UK to study Mechatronics, while Bhagya made his way to Singapore for a degree in Biomedical Engineering. 

While in Singapore, Bhagya made his first steps in the hospitality solution industry by working on a food discovery platform. He wrote more than 350 for the platform’s blog until it was acquired by the Uber equivalent of the region. By writing all those reviews, Bhagya learned a fair bit about the inefficiencies of how restaurants operate, especially when it came to customer experience. 

He knew that technology could improve customer experience and started looking into mobile ordering as a way to do that. Around the same time, he reconnected with Jay and found out that his friend, too, was thinking of starting a business along the same lines. They joined forces and laid the foundation of Urbandine. 

“We started out by developing a solution that would allow customers to order and pay at restaurants directly from their mobile phones. At the same time, we were also doing market research and we looked at Singapore as a possible entry market,” says Bhagya. Yet, with some competition already there, they quickly changed course and turned their eyes to Europe. “We had both been to the Netherlands for leisure and had noticed that there were always a lot of vacancies for restaurant or cafe personnel. We thought this might be a good place to start, as there is certainly a product-market fit.”  

What also tipped the scales towards choosing the Netherlands were the possibilities that it offered to non-EU entrepreneurs. Jay flew in in late 2018 to meet several facilitators who could help them apply for the Startup Visa. YES!Delft was one of them. 

In proving that they can add business value to the Dutch market, Jay and Bhagya applied for YES!Delft’s Blockchain/AI Validation Lab, sailed through their Selection Day and joined the program in early 2019. The rest is history.


The Validation Lab turned out to be exactly what Jay and Bhagya needed to establish their solution on the European market. “During the 10-week program, we got to meet with over 60 restaurant owners and validate the need for our product,” Jay says. “We quickly identified beach clubs as a potential market segment, as they often have large terraces that are difficult for waiting staff to service at all times. We ran a pilot with two beach clubs in Scheveningen, starting in August 2019, and managed to bring in new revenue lines for them.” 

While beach clubs rely on customers to sit down and order at their location, with Urbandine they could also get orders from people on the beach, thus getting a boost in sales. This finding proved to Jay, Bhagya and restaurant owners alike that there is unexplored value to be derived from a solution like Urbandine. 

Still, having only beach clubs as customers was not going to be enough to run a self-sufficient company. It is a seasonal business and the two co-founders knew that rather well. 


Between the end of the season for beach clubs, which is around October, until February 2020, Urbandine made itself known in a different market segment. “We offered our technology for use at events and made it possible for visitors to order food and drinks from a number of different vendors,” Bhagya says. 

One of those events was Horecava, the largest annual hospitality trade fair in the Netherlands. For the vendors at the event, having Urbandine as the solution to order food and drinks meant more business, while for the event organisers, it meant more interaction on the floor. 

For Urbandine, the buzz generated by this move was crucial. It was an opportunity for them to have restaurant owners, who were the key target audience of the event, experience their solution from the other side of the table, as the customer. “The feedback we got was invaluable,” Jay says.

hospitality solution

It would only be fair to say that Jay and Bhagya have made leaps of progress since they first moved to the Netherlands just over a year ago. They have also secured a convertible loan of 100,000 euros from six Dutch investors and UK-based entrepreneur Agash Navaranjan, who has since joined Urbandine as co-founder and CTO.

To keep growing at the same, and an even higher pace, the team needed to kick 2020 off strong. For one, they wanted to make sure that they open the season together with terraces in the Netherlands. Yet, nobody could have predicted a global pandemic slowing them down as it did. 

“March has been quite dormant for us, but that doesn’t mean that we have not been working on our proposition,” Jay says. “We have stayed in close contact with our customers and are jointly looking for ways to restart operations once the current measures have been lifted.” 

“We want to offer Urbandine for two months for free to help restaurant and cafe owners to get back on their feet as quickly as possible,” Bhagya adds. “So far, restaurant owners have reported a loss of about 90% of revenues due to closing down their physical locations and they’ve had to cut ties with a lot of their flexible workforce. It is much harder to bring workers back than to let them go, so we want to help owners in this transition phase. We are preparing the restaurant market for a scenario where they would have to work with fewer waiting staff and keep 1.5m distance to their customers.” 

At the moment, the team is talking to more than 150 customers and is aiming to launch their solution with them as soon as the restrictions have been lifted. Urbandine wants to make it easier on restaurant, bar and cafe owners to do their job post-COVID-19, but they also want to establish themselves as the go-to solution for even better and more efficient customer service. 

Given their growth and business approach so far, even in difficult times, it is clear that Urbandine takes challenges in stride and turns them into opportunities. And it can only go up from here.

About a third of all food produced goes to waste, and more than 30% of that one third is lost before it reaches the supermarkets. This data may seem shocking, but what’s worse is that it’s real. The reason for this is that quality control with the products is often done by people and problems are not detected in time.

This doesn’t have to be the case, though. With their solution, the team of Mythronics makes it possible for vegetables and fruits to be graded and sorted autonomously, thus minimizing error and maximizing efficiency.


For founder Soheil Jahanshahi, starting a business for the agricultural industry was not a hard decision. “When I was a kid, my father and my uncle had an apple farm back home in Iran, so agriculture has always been close to my heart,” he says. “In a time when people are moving more towards consumption of high quality fresh products, it is crucial that more and more fruits and vegetables (among others) reach the supermarkets in a good condition.”

The key to making that happen is by sorting and grading the product at the right time. Yet, in this specific industry segment, there has been – and still is – a shortage of qualified labor, Soheil says. Technology can fill this gap.

“From speaking to many (potential) clients, we found out that there are simply not enough people to do the job,” he explains. “Quite often, companies have to hire people from abroad and invest in training them, only to see them leave in a year. We want to avoid that.”

With a background in software engineering, Soheil knew that he could tackle this challenge and help decrease food waste in the value chain. With Mythronics, he and his team of three are developing solutions based on Artificial Intelligence (AI) and robotics that can: (1) detect when plants are ready for harvesting, (2) detect defects and other attributes in the product and (3) help with sorting it.

A simple idea that they have taken to the market in under two years.


Soheil and his team are certainly up to something, with their ultimate goal to make AI more understandable and accessible to businesses in the agricultural industry. Naming the company Mythronics was also not a coincidence. “For many people, AI is still a myth and we want to change that,” Soheil says.

Supporting them along the way has been YES!Delft and their network of experts and mentors. Soheil joined the AI/Robotics Validation Lab in May 2018 and quickly learned about how to match his business proposition to the right target market.

“I met with a lot of potential clients, which helped me validate my idea and better understand the market I was aiming for,” says Soheil. “I also got exposure to a wide range of investors.” Only months later, Mythronics was accepted into YES!Delft’s Accelerator program.


Today, the startup is already testing their product on several commercial solutions. The team is targeting two different market segments – greenhouse owners and growers on the one hand, and companies on the packaging and logistics side on the other.

For greenhouses, they have developed a mobile assistant that can autonomously detect problems with the crops. It can also tell them when certain crops are ready for harvesting, eliminating the need to train people for it.

On the logistics side, Mythronics has focused on developing an AI-driven solution that can help eliminate subjective quality inspections and ensure that all products are in the high quality sought after by supermarkets.

“We are building this product together with our customer, ABC Logistics,” says Soheil. “In essence, we’ve created a sorting box with sensors and an integrated technology that grades fruits. So you can put up to 60 different types of fruits on a conveyor belt, run them through the box, and it will identify each of them individually. As they go through the box, a robotic arm helps sort those fruits.”

In the relationship between the two companies, ABC Logistics has been providing a lot of the knowledge and a test site, while Soheil and his team have been bringing the technical expertise.

With two solutions already out for customers to work with, the team of Mythronics is well on their way to fulfilling their goal of reducing food waste, even if only on a local scale for now.

YES!Delft startups contribute to solving the corona crisis

There is no doubt that the current COVID-19 developments are changing the way people go about their daily lives and the way they work. For entrepreneurs, in particular, those are times that test their ability to not only adapt to this new situation, but also find creative solutions to contribute positively to it. 

At YES!Delft, we are lucky to have some of the brightest examples of innovation, creativity and technical excellence. From developing new generation air purification and ventilation technologies, to smart solutions for diagnosing and monitoring patients at home, to using UV light to disinfect medical equipment in a matter of seconds, startups are working around the clock to add their value to the current situation. And they’re not the only ones.

Contributing to a cleaner living and working environment

VFA Solutions, in which VFA stands for Virus Free Air, is an expert in the field of Indoor Air Quality (IAQ) and filtration technologies. Its work focuses on air cleaning and disinfection from hazardous airborne contaminants such as fine particles as well as bio aerosols like bacteria, viruses, spores and fungi, among others. “The corona crisis feels like the last droplet that the market needed to realize the importance of proper air quality and its impact on people’s health,” says founder Eliane Khoury. 

VFA’s ASPRA air purification solutions help purify indoor environments – and at the moment largely healthcare institutions – by removing airborne viruses, pathogens and dust particles. “Inside our device, bio aerosols are guided through an electric field, where the majority are killed or deactivated. The viruses, bacteria and other pathogens are then captured in the collector (the filter) and permanently removed from the air, thus reducing the risk of spreading.”

Because sales volumes are growing for VFA, yet certain components are either not available or have a long delivery time, the team has had to be creative and has decided to simplify the design of their products and outsource production to partners and suppliers. 

UV Smart, another startup in the YES!Delft portfolio, also plays its part in helping hospitals and healthcare centers maintain a clean working environment. Born out of the need to minimise the spread of resistant organisms and viruses, and maintain the highest possible hygiene in  healthcare, the company has developed an innovative solution based on UV light that helps disinfect medical instruments and devices within seconds. 

Since the COVID-19 outbreak, a number of hospitals in the Netherlands have approached the team to use their technology in disinfecting face masks so medical personnel can reuse them. “We have been working around the clock on a suitable solution for our customers,” says co-founder Daan Hoek. “The first 20 products with our technology are being delivered to different hospitals in the last week of March. From now on, we have to scale up production as fast as possible to get our devices available for the various hospitals.” 

Daan and his team are also thinking about ways to offer their technology internationally.

Working towards more efficient and risk-free screening

Without question, healthcare professionals are among the people who are most exposed to the risk of contracting the corona virus. Hospitals have taken multiple measures to curb that risk and startups are looking for ways to contribute. 

Innovattic is a company that builds digital solutions for social impact, including apps, websites and serious games. Since the coronavirus has been spreading, the startup has been approached by the Leiden University Medical Center (LUMC) to develop the CoronaBox, a medical kit that (potential) patients can take home to do a self-check.

“We are making a CoronaBox with a thermometer and an oxygen saturation measurement device so potential corona patients can go home and do the necessary measurements,” says Lauwerens Metz, CEO of Innovattic. “That way, they will not infect other people in the hospital and at the same, the box can help monitor them from their home in case their health deteriorates fast.”

This solution can not only help screen more people, but also allow healthcare personnel to focus on the cases that are most urgent, without losing the overview of everyone else who might need their attention. 

For those patients who do need to be examined at the hospital, though, Delmic has developed a different solution. As a spin-off of the TU Delft and the materials institute AMOLF, the startup makes microscopes for (academic) research in materials and life sciences. “Our current proposal is not in our core business at all so that has been a big change,” says CEO Sander den Hoedt. Yet a change that he and his team have embraced in order to help minimise the impact of the coronavirus. 

What they have developed is called the DAAD system, or the Diagnose At A Distance system, which makes it possible for medical staff to examine potential patients without coming in direct contact with them. 

“This solution allows doctors to screen patients without using personal protection measures, thus reducing the chance of doctors getting infected as well as patients getting infected from their protective gear.” The first system is being rolled out in the last week of March and Sander and his team are looking to scale their solution from there. 

Somnox is a startup that is developing a soft robotic that makes sure users have the best night’s sleep possible. Over the past few weeks, the team has adapted to the current coronavirus developments in several different ways. On the one hand, they have made all their sleep knowledge available for free since “sleep is an amazing immune system booster,” says CEO Julian Jagtenberg. On the other hand, “we are also making some of our products available for healthcare employees to borrow so they can get the rest they deserve for free.” 

In addition to that, Somnox has also taken on a more creative approach to contributing to the current corona developments. With the help of the 3D printers in their office, they are making ventilation masks out of Decathlon snorkeling masks and aim to deliver them to hospitals that are preparing for the peak. Anyone with a 3D printer is encouraged to join. 

In the meantime, Eliane from VFA has also been busy setting up a new, similar initiative to fight the shortage of face masks for healthcare personnel. 

At the end of the day, solving this crisis is about innovation, creativity and working together, and those startups seem to be on the right track. 

Elemental Water Makers: Turning water scarcity into abundance

For a country like The Netherlands where rain is a given and the sea level is often as high as it gets, the topic of water scarcity may not be the first to come to mind. Yet, for entrepreneurs Sid Vollebregt and Reinoud Feenstra, this issue holds a sense of urgency: “Already today, about two thirds of the world population is facing water shortages”. 

As a result, the two of them founded Elemental Water Makers and developed a sustainable desalination technology to provide water scarce areas with fresh water.  


Sid and Reinoud’s idea goes back to their time at the TU Delft when they were doing their graduation project in the field of desalination and renewable energy. “We founded Elemental Water Makers as a result of our research, and with the sole goal of solving fresh water scarcity using only the elements of the sea, sand, earth and wind.”

About two thirds of the world population is facing water scarcity, Sid says, which makes the company’s efforts so much more important. 

While Elemental Water Makers is about making fresh water more accessible to those who need it the most, it is also about achieving that in a sustainable manner. “Desalination processes do exist and they are similar to what we do, but they are powered by fossil fuels – so, conventional electricity. What we can do is offer either a cheaper and/or a sustainable solution,” Sid explains. 

With the smart use of renewable (solar, wind and wave) energy and gravity, Elemental Water Makers’ technology allows for a constant desalination process. 


Today, the team is focused on implementing its technology on islands with limited access to fresh water. While having completed more than 20 projects to date and being active in over 10 countries, Sid admits that it was customer development that had proven to be one of their main challenges starting out.

“You can use desalination technology to provide fresh water for a wide range of customers – from hospital to resorts, to entire municipalities,” Sid says. “What we wanted to find out was who could benefit the most from our technology.”

To get a better understanding of their target market as well as the ins and outs of running a business, the two entrepreneurs joined the “Ready to start up” course, followed by YES!Delft’s Incubation Program, the former Accelerator Program. “In the early stages of our development, it was very valuable to be among entrepreneurs and to tap into this network of people and advice, especially the financial and legal coaching,” Sid says.

Becoming part of this ecosystem was the initial push both founders needed on their way to success. Perhaps the most intense part of their idea validation process, however, was when they decided to hop on a plane and visit various islands to talk to as many customers, suppliers, regulators and other stakeholders as possible. 

It was then that they secured their first customer, too. 


With a number of successful commercial projects behind them and more than five team members onboard, Elemental Water Makers is working towards new heights. 

Together with various coastal regions, the team aims to prove that fresh water can be delivered at an affordable price and in a sustainable manner to regions that do not have access to it. Take the African island of Madagascar, for instance. Eleven million on it still do not have to clean water and about 85% of the population lives in remote communities. Efoetsy is one of these communities. 

In 2019, Sid and Reinoud launched the Elemental Water Foundation, a certified NGO with the goal to help people that need it most. Together with its local partner Trans Mad and the support of private sector donations, it successfully raised the funds required for the installation of the solar-powered desalination system. Thanks to this project, the community now has access to 15,000 liters of clean water every day.

To make implementation of the technology easier, Elemental Water Makers has developed a containerized plug-and-play solution that can be deployed quickly and easily to ensure the reliable supply of affordable clean water at any coastal location.

Sid and his team have come a long way since the early days of their company and have, so far, enabled multiple communities across Africa and Central America gain access to fresh water not only in an affordable, but also environmentally-friendly way. 

“Many people are starting to understand the topic of water scarcity and the importance of water,” Sid says. “For us, it’s not just about solving a problem: We’d like to get to the point where we turn water scarcity into abundance.”

Applied Drone Innovations: Leading horticulture into a data-driven future

Drone technology is gaining momentum. While until not long ago, it used to be in the hands of either larger companies or of consumers who would use it for fun, today, drones are accessible to businesses of different sizes and industries.

Agriculture is no exception. With the right tools and data, growers can monitor their crops in near-real time and make sure they remain healthy. To make that possible for horticultural businesses, Applied Drone Innovations (ADI) develops greenhouse monitoring systems, and collects and processes valuable data to increase crop yields and quality.


It was back in 2015 when William Simmonds, Lucien Fesselet and two fellow university students came together during an Engineering Entrepreneurship Minor at the Inholland University of Applied Sciences. As part of an assignment for the horticultural department, they were asked to visit a local plant producer, Bunnik Plants, and find out if there was a problem they could solve for them.

“We went there, spoke to the growers and asked them about the challenges they were experiencing,” William remembers. “We flew our drone around and talked about the opportunities drone technology could offer.”

A single kick-off meeting was enough for William, Lucien and the rest of the team to realize that there was business potential in introducing drones to greenhouses. They started working on a case and quickly attracted interest in their idea, which won them the Wij Inholland Award and a cash prize of 2,000 euros. 

“It was enough to launch a website and print some business cards,” William says. “It was the start we needed.”

What followed was a lot of hard work, long days of research, testing and market validation. In 2017, the team joined a two-year education project of High Precision Greenhouse Farming (HiPerGreen) which gave the idea exposure and the possibility for 60 students to work on it and further develop it. William and Lucien, as the two co-founders, kept busy with that, together with university teaching and work at other startups, while getting ready to lay the foundation of ADI. 


Less than a year later, ADI was already founded and looking for ways to put their solution on the market. “We applied and got accepted into the YES!Delft Validation Lab and got to learn what it’s like to turn a research project into a business,” William says. 

“We learned how to ask the right questions and find our product-market fit. We understood the importance of having the right contacts and growing our network.”

It was with the help of YES!Delft that the team of ADI got their first pilot projects and later their first paying customers. It was there that they got in touch with Rabobank and secured a 150K startup loan. And it was also there that they learned that their business proposition wasn’t really about the drone itself, but about the data and what growers could do with it. 


Today, ADI is focused on providing customers with the data collection and analysis tools they need to keep their crops healthy and improve operational efficiency. Together with Beekenkamp Plants, the team is working on a mobile data collection platform that provides the customer with information about germination processes, and uses advanced image analysis to determine the quality of crops. 

ADI has recently delivered a proof of concept of one of its most recent developments, a germination analysis machine.

Since their early startup days, William and Lucien have come a long way. They have grown their team to over 10 members and in less than one year, they have raised half a million euros in grants and funding on top of the initial startup loan. 

The latest milestone is 350K from the MIT R&D grant, in which the company was the lead applicant. “We’re going to use this money for a specific project where we will work closely together with partner Avular, an Eindhoven-based startup focused on enabling mobile robotics,” William says. “We will focus on further developing the data analytics part of our solution, while they will work on making it more user-friendly and suited to operate in greenhouses. 

To date, ADI has three paying customers – two in the orchid industry and one in the young-stage vegetable industry, and several ongoing pilots. And if you ask them about their key goals for 2020, the first one on the list is keeping those customers happy. “To be successful, we need to make sure we do that all the time,” William says. 

ADI would also like to further expand its team and aims to raise 2 million euros in funding within the year in the ambition to become the Google of Agri Data. “At the end of the day, we want to invest more in our core image analysis technology and bridge the gap between image processing and biology.”

Physee: Making buildings future-proof

Becoming energy-neutral is not just a trend anymore, it is a necessity. It is a necessity across generations, markets and industries, and especially when it comes to people’s day-to-day lives. So then imagine living in a building that absorbs sunlight energy during the day and uses it to keep you warm at night. Or working in an office that aims for the ideal temperature and air quality to make you as productive as you want to be. 

All of this is now possible thanks to Delft-based company Physee and its patented SmartSkin technology, which can autonomously power, sense and regulate a building’s climate.


It all started back in 2014 when Willem Kesteloo and Ferdinand Grapperhaus decided to work together on the Master’s theses degree at the Technical University in Delft (TU Delft) and focused their research on the physics on luminescent materials. 

“We had known each other for some time and we knew we worked well together so it was a great opportunity to join forces on the same research project,” Willem says. What started as a university assignment soon led to some interesting discoveries in the lab, and to the idea of turning them into a business.

But what were those discoveries exactly? While researching the luminescent properties of a specific metal, together with their supervisor Erik van der Kolk, Willem and Ferdinand found that, in certain states, this metal can absorb a very broad spectrum of light, which it subsequently emits in a very sharp peak outside of its absorption spectrum. The novelty of this discovery prompted them to think that there might be business applications to consider, like making buildings more energy-efficient by capturing light and using it to generate energy. 

“I have long had an interest in sustainability and the energy transition, so I was excited at the prospect of developing a new technology to make buildings more energy-efficient,” Willem says. “We spend 90% of our time in buildings, which consume 40% of our global energy demand.” And eventually, a lot of that energy ends up being lost through the facade. 

Willem and Ferdinand knew there had to be a solution to not only use, but also generate and reuse energy inside buildings. Straight after graduation, they decided that there was only one way to find out if their idea had business potential, so they rolled up their sleeves and laid the foundation of Physee.  


In the first year and a half, it was just the two of them trying to develop a proof of concept and figure out their next steps. As physicists, though, they didn’t know much about business, Willem admits. They didn’t know how to find their product-market fit, how to pitch, raise funds or build a great team. 

“This is where YES!Delft came in,” he says. 

“We first joined the LaunchLab [now Validation Lab] and later continued onto the next program. YES!Delft taught us to get out of the building and find out what’s out there; who are our customers and what can we do for them. Because for us, of course, it was obvious – who wouldn’t want electricity-generating windows?” Willem laughs.

Today, Physee is a team of 45 people, all united around the mission of using smart technologies to make buildings more sustainable and energy-efficient.  


The SmartSkin technology that they have developed solves challenges on a number of levels for a number of market segments. “In my opinion, facades are still being built in a very low-tech and inefficient manner,” Willem says. “What we do is leverage technology to use light more effectively.”

SmartSkin was developed to tackle various challenges at the same time. On the one hand, there is the software, which essentially makes it possible to create smart windows. It combines sensor data, weather conditions and user settings to reduce buildings’ energy consumption up to 20%.

On the other, there is the hardware component. The company has patented a technology that integrates solar cells into the glass of normal windows and harnesses electricity from the sun. That way, the light – and therefore energy – that would normally be reflected off the facade is now absorbed and put to use.

The third and perhaps most complex element to Physee’s work is the development of glass coatings. “We are working on two types of coatings – one for real estate and one for greenhouses – and we are doing so with some of the biggest glass manufacturers in the world,” Willem says. Finalizing those coatings is on their list of goals for 2020.

As a company aiming to revolutionize how buildings are designed and built, Physee works together with a variety of stakeholders to spread its products and services as widely as possible. And it seems there is a market for each of them: Two of four main global glass manufacturers are mainly interested in the coating developments, while the other two have larger interest in the smart hard- and software components. The real estate industry, in turn, is mostly interested in the software and the ability to create intelligent building facades.

From this point onward, Physee is looking towards expanding its team even further – because “our team is our biggest asset,” as Willem puts it, closing a Series A round of funding and starting its first international projects in Spain, Germany and the UK. 

There are big goals on the horizon for Physee but they are goals that the team can surely take on.
