Mangostone: from a master thesis project to paying customers

The fashion industry, the 4th most polluting industry in the world, is known for the constant provision of new trends at extremely low prices. This led to a significant rise in the amount of clothing created and discarded in landfills.

Mert Ozturk, writing his master thesis in Supply Chain Management at Erasmus University in Rotterdam, started working with Climpex, a textile collection company, to help them optimize their processes. The thesis project, which started in 2019, led to the founding Mangostone in February 2020, with Climpex being the first paying customer.

How did that happen?

Climpex had multiple containers on the streets where people could discard their unwanted garments. The challenge they faced was that they did not know what and how much there was in the containers, making it hard to decide which roads to take.

“Textile is quite difficult to predict compared to general waste streams. We saw there was a lot of room for optimization. For example, there were times where the containers would be only 10-12% full, and they would need to drive 100 km for that.”- Bas Hoogakker

As a solution, Mangostone thought of a “centre that was better in terms of technology, but also cheaper”. That’s when they knew they had to create a whole cloud software package that works on centre data or predictions (using advanced preventive algorithms) to better optimize the processes.

The focus of Mangostone

The target market of Mangostone is defined by the textile collectors (both commercial and charities) that sell the clothes to textile sorters. After the sorting, everything gets in the hands of textile processors. The clothes end up either in the stores that resell the garments, either on the market of 2nd or 3rd world countries or in companies that have better recycling techniques and can create new garments out of the old ones.

When they started working with Climpex, most of the company’s operations were defined by driving through different locations nationally and collecting the garments from people’s houses. The remaining was defined by the containers, which were only a couple of hundreds. Now, that number has been multiplied many times with the help of Mangostone. Their complex logistical operation was now much cheaper and easier to control.

Looking at the competition, Mangostone is not the only IT company that provides this type of product. They have a few big competitors, yet they focus mainly on the general city waste collection and not textiles. Their direct competitor in textiles does not use advanced software for waste collection, leaving room for Mangostone to educate them.

In terms of funding, Mangostone “pulled out a smart move” since they had the right set of skills within the team. They developed the software themselves and, the chip shortage gave them a new insight: “80% could be predicted without investing in the hardware”. That being said, they sold the software based on a subscription business model allowing them to cover the expenses and reinvest in the development process without needing external funding.

“We did work for 2 years for free, that’s basically the main investment: our time.”- Bas Hoogakker

The impact of YES!Delft

Initially, Mangostone was not sure they needed help from YES!Delft, or at least they did not know they needed it. However, once they spoke with the start-ups that are now scale-ups, they learnt about their experiences and saw how enthusiastic they were about working with YES!Delft.

“From week 1 or 2 we saw that it was worth the money. We learnt a lot about soft skills- both personal and team development, how to be a bit abstract with the ideas and actually address the elephant in the room. Also, the lunches were great”- Bas Hoogakker

Mangostone also benefited from the network of YES!Delft, their advisors, and working with other start-ups that were eager to win. Since they were one of the only start-ups with paying customers, they shared their knowledge with the others and got valuable information in exchange too.

Mangostone kept in touch with their mentor from YES!Delft, and have been advised to stick to the niche they are in for at least 1-2 years before expanding towards another direction. For now, they selected some target markets for the extension, which are The Netherlands, Germany, the United Kingdom, and potentially Denmark. Their goal is to get more customers and build a name and a well-rounded system for the collection of textiles which can facilitate the sorting processes.

Your dream can become a reality too. As long as you want to make a change, don’t miss the opportunity to boost your start-up by joining the YES!Delft Validation Lab or Accelerator Program.

Respyre: from lab to real-life environment

Urbanization and climate change need the development of new solutions to sustain and improve the quality of life in our cities. ‘Green cities’ benefit the biodiversity, climate, wellbeing, and air quality, assuring the improvement of the inhabitants’ lives.

Respyre is an aspiring pioneering company that has joined YES!Delft in spring 2022 with the ambition to contribute to the concept of green cities. Respyre has created an innovative, patent-pending, bio-receptive concrete solution that allows moss to grow after hardening. Their solution can be conveniently applied to existing structures while also being efficiently incorporated into new constructions. This makes their product a quick, simple, low-cost alternative to façade covering that can also benefit the urban environment.

From research to a business idea

Respyre looked at the research conducted by TU Delft on why mosses grow on different surfaces next to the railways with the scope of assessing whether it harms them. The conclusion was that the moss does not eat the concrete, yet if the railway’s operators want to prevent them from growing, they should use concrete that does not contain certain characteristics. That was the moment when Mark de Kruijff turned the idea into a business concept. Auke Bleij, his friend, got very excited about the sounds of it and decided to join the company shortly after that.

Auke explained that “many unused vertical surfaces can easily be turned into air filtering or water retaining surfaces”. He saw the potential of this idea and described this experience as being one of the few when he was “intrinsically motivated to keep on working”.

Respyre’s current target market is represented by the infrastructure operators, real estate, and the government (municipalities). Defining the target market helped them launch different paid pilot projects. One of the most exciting pilot projects was with the Municipality of Amsterdam, where they were asked to cover two bridges. Amsterdam has a lot of bridges that are constantly covered in graffiti, and by collaborating with Respyre, they could create “a natural shield”.

“What we try to do is to reach enthusiastic municipalities and empower them as pioneers of the product: meaning that they have the product and use it the way they find fit.”- Auke Bleij

Looking at where Respyre is to be positioned in the market, their biggest competition only focuses on brick and mortar. “That’s also where we want to compete as well. We want to make this as good as brick and mortar.” Their products are not supposed to be “an alternative for vertical greening, but an alternative for façade covering”.

According to Auke, “The Netherlands is a great country for start-ups” since there is a high interest in investing in unique ideas. Within the next couple of months, Respyre aims to gather between € 300-500k. This investment is meant to create “market-ready products”, with the goal of not only having a nice concept but a predefined supply chain and production site, among others. At the moment, they aim to do that by getting affordable loans for social investments and paid pilots with companies who trust the product or want to contribute to the concept’s success.

In a later stage, after 12-18 months, Respyre will then start looking at large rounds of investments (a couple of millions). These investments are expected to happen through private investors, crowdfunding, but also RaboBank, Angels Investors and Innovation Fund of Holland.

In this process, YES!Delft has played an essential factor in the growth of Respyre. The company was offered the general picture of what they have to think about as a business as well as the tools that they need to start building it. Apart from that, they could use their community and network, which has also made it easier to talk to investors.

You have an Excel sheet for everything, and you can easily get your questions answered”- Auke Bleij

The next steps for the upcoming 6-12 months of Respyre is to pay a lot of attention to the pilot projects and everything besides that such as keeping the company going, getting funding, expanding the team, maintaining the website, and formulating different strategies.

“The pilots help validate the business model and the problem-solution fit and, at the same time, it helps us understand our products better.”- Auke Bleij

Your dream can become a reality too. As long as you want to make a change, don’t miss the opportunity to boost your startup by joining the YES!Delft Validation Lab or Accelerator Program. However, if working for a startup resonates more with your ambition, we got you! Check out the vacancies on our YES!Talents page!

Kitepower: leaving the world a better place

In 2016, a young and motivated engineer, Johannes Peschel, together with his university professor and mentor, Roland Schmehl, founded Kitepower. Kitepower is a pioneering start-up in Airborne Wind Energy (AWE) that generates innovative and cost-effective alternatives to traditional wind turbines. 

It is well-known that wind energy has several advantages, being one of the world’s fastest-growing energy sources. Yet, it comes with different challenges. One of them has been overcome by Kitepower, who developed a product that is remote and does not need good land-based wind sites. Kitepower Falcon uses a ground station, a kite to produce electricity and a robot that flies with the kite and controls it.

What is the story behind Kitepower?

Before the company’s launch, Johannes was a full-time computer science student passionate about kite landboarding. One day during that period, in the centre of Berlin, one unfortunate story turned out to be an amazing business idea that could impact others positively. Johannes broke his arm practising kite landboarding. Some would think, ‘how can you get a business idea by breaking your arm?’. Well, Johannes decided to think further than what seemed to be a very painful event. 

“When I broke my arm landboarding, I experienced the power of the wind: it can blow you up but also drop you down quickly. After that, I said to myself, ‘maybe we can do something better with that energy’.”- Johannes Peschel

After this event, Johannes researched the topic and found out that TU Delft was already working on it. Before he knew it, he moved to The Netherlands and embarked on a journey to make this idea happen. Kitepower started by providing renewable solutions for temporary power to the end-users of the electricity in remote places.

One of the company’s biggest accomplishments is their recent Aruba project that took place in the context of a military exercise with the Dutch Ministry of Defence. Kitepower, as a partner, aimed to develop and test an innovative energy system to support its decarbonisation efforts. When this became a reality, Johannes was thrilled.

“When we first started the company, I had to arrange a photoshopped image of a kite flying on an island, and now that is irrevocably the reality!”- Johannes, in an interview with Green Tech Alliance

Kitepower built credibility by proving that its technology works. That’s how from a start-up, the company became a scale-up. At this stage, when looking at the competition, Kitepower is proud that it managed to surpass companies that are in the business for 13 years, simply because they have a “very simple and easy product”. 

“There are companies that have more funds available and could be that they are more technically developed due to these resources; however, we were the first ones deploying the system on an island, imagine where we could be if we had more financial resources.”- Johannes

So far, Kitepower has achieved its goals through motivation and hard work. However, things would not have happened without financial support. They have been funded via grants (e.g., fast track innovation, European funds), investors, launching customers, and now impact funds. From the European Union, they have received amazing feedback for executing the project with excellence. 

How has YES!Delft helped along the way?

Kitepower profited from training on how to make a company successful, getting the help of experts in different fields, a wide network, and of course, help with funding from YES!Funded. Another important factor was the credibility from the public that came by being associated with YES!Delft.

“YES!Delft came in handy because they had experts for everything, and whenever we would have a problem, we would call and get assistance.”- Johannes

As for the future, Kitepower aims to get people involved in the crowdfunding campaign and then use the resources to make its products available for everyone through festivals and events. They want to show people that their technology works and is safe and reliable with a positive, sustainable impact. If you are interested in joining the crowdfunding campaign, you can find more information here.

“Our vision was always to do this for the people and have them profiting from it.”- Johannes

One thing is for sure: when you have a vision and when you put in the hard work, things do become reality. Believing in your dream and taking action will bring you the right results. For now, Johannes worked on another dream where he “photoshopped the picture of Aruba with more and bigger kites above it”.

Your dream can become reality too. As long as you want to make a change, don’t miss the opportunity to boost your startup by joining the YES!Delft Validation Lab or Accelerator Program. However, if working for a startup resonates more with your ambition, we got you! Check out the vacancies on our YES!Talents page!

Dimmes Doornhein

Dimmes Doornhein: A strong team is at the heart of every successful company

For a young startup, having a coach who has worked in a wide range of roles and markets sure is invaluable. And when you add to that his passion for building great teams and companies, there is little left you can ask for. Dimmes Doornhein is among YES!Delft’s Entrepreneurs in Residence (EiR) – an experienced founder and investor himself – who is looking to share his knowledge with the new generation of young entrepreneurs.


At the age of 70, Dimmes not only has valuable lessons to share, but he also brings the type of energy and sparks that many young founders need to ignite their confidence. 

Having worked in the fields of city redevelopment, telecommunications – in particular during the liberalization of telecom companies in the 80s, to more recently being involved with newer technologies such as artificial intelligence (AI), Dimmes has a wide range of experiences to draw from and pass on to others. 

Yet, perhaps what he knows most about is not a specific field of technology. It is people. It is building and growing successful teams. 

“Throughout the years, I have worked in many multidisciplinary teams and what is characteristic about such teams is that on an individual basis, everyone is brilliant. But then you put them all together and things don’t always work.” In other words, a strong team needs the right chemistry, not just the brightest minds. 

Putting the right teams together and helping them shape the companies of tomorrow is one of the areas that Dimmes focuses on when coaching young founders. What’s more, he makes sure to create the environment entrepreneurs need to shine and grow as individuals, while contributing to the development of the wider team.

While he’s worked in a variety of roles during his career, Dimmes has most often ended up in the position of manager or CEO. In that, he has had hundreds of people working with him. 

Not for him, he emphasizes, with him. 

“The role of CEO is to be a leader and bring the best out of everyone,” he believes. “Probably half of the people I have worked with were smarter than me and I find it important to acknowledge that. It is important to give people the space to do what they are best at as they contribute to the goals of the team.”

Bringing market experience together with the knowledge of complex tech

What Dimmes likes most about working with young people is that he gets to bring both his successes and mistakes, while they bring inspiration, fresh ideas and insights on new technologies. In a way, it is the perfect recipe for bringing together real-life market experience with very specialized technologies.   

One of those technologies comes from the team of YES!Delft startup Flexous. Dimmes is currently with the team and believes their innovative approach to horology has the potential to revolutionize the watch industry. An industry that is hundreds of years old. “If you dare to revolutionize and you do it right, you can become really big,” he says.  

Over the past months, Dimmes has been mentoring the team of Flexous and now sits on their recently created advisory board. “I don’t know it all,” he admits, “but I am here to advise, ask the right questions and ignite people’s creativity.”  

Next to being the person that teams can get advice from, he also strives to be someone they can confide in. “I am there so people can talk to me and know that what they tell me will never leak.” In other words, he creates a safe space for teams to share and work out their differences. 

And why does he do all that? 

In his experience, it is really difficult to keep a team together. In fact, not having the right team and being able to move forward as one is among the three main reasons companies fail. It is, therefore, crucial that startups have things properly set up from the get-go.  

“You need to get things right from the start,” he says. “Think about this. If you leave the port of Rotterdam for New York and you make a mistake of two degrees – just two degrees – you will end up in Rio de Janeiro. This is why it is so important to have the right guidance and avoid any mistakes from the start.”  

Without a doubt, strong teams are at the heart of being successful. Yet, building such teams is easier said than done, especially for young entrepreneurs who have never experienced it before. For those within the YES!Delft community, the knowledge of how to do that is there. And Dimmes is one of the sources of that knowledge.

Tiler: Building the future of wireless electric charging for bikes

“We want to contribute to making cities greener, yet cities are largely built around cars,” says Christiaan van Nispen, founder and CEO of YES!Delft startup Tiler. “We have identified the need for creating a better infrastructure for electric bikes and are working on a solution that would provide new charging opportunities.”

Electric bikes need the right charging infrastructure

Having been in the business of building sustainable solutions for over a decade now, Christiaan knows what it takes to develop technologies that need time to develop and mature. It was back in 2009 when he started his first company with the goal of making buildings more sustainable. “Back in that day, such technologies were still very new,” he remembers. And while he ended up selling his share of the company, it had taught him plenty on how to develop complex technological solutions and bring them to market.

His connection to the world of sustainability was perhaps most notably forged while working as Innovation Manager for a German company. On behalf of it, he went to the US to set up the company’s footprint of electric vehicle charging stations, which is also where he got to know more about electric vehicles in general. 

“In a meeting that I had with Uber, they told me that light electric vehicles – electric bikes, in particular – will be a big thing in the future.” This was an important insight for Christiaan and what eventually got him thinking on how to build better infrastructure for this mode of transportation. 

He started Tiler (at that time Fesla Charge) in April 2019 with the mission to offer a wireless charging solution for e-bikes and has been checking off one milestone after the next since then. While he was the sole founder at the start, he was later joined by founder Olivier Coops as COO. Joris Koudijs joined the MT as CTO in 2021. The startup has also raised more than 1 million euros from UNIIQ, Delft Enterprises and PVS investments, among others, which has helped it develop its technology fast and enter the market in the Netherlands. 

“Our solution is technologically challenging so we started with a pilot almost immediately,” Christiaan says. They partnered up with Ahoy to see how the technology would work and if it would meet the client’s expectations.

“It was a learning process on what it is like to build a hardware solution,” he says. “Perhaps the main lesson we learned is that it always takes a bit longer than anticipated. The first minimum viable product (MVP) for Ahoy was planned for September 2019, but instead it took until July 2020.” It was certainly not an easy endeavor to take on. 

The team also learned about how to make their solution as easy to use as possible, as well as durable and sturdy. Today, Tiler’s product is essentially a block integrated in a smart kickstand, which could also be used in other light electric vehicles. “The whole idea behind our solution is that users would have a seamless experience throughout – you come, you park, you go.”

On the path to making cities greener

While Christiaan started Tiler with the simple mission to create the necessary infrastructure for electric bikes to thrive in cities, they now have a team of six that are working tirelessly to make this possible. Yet, not without the support of fellow entrepreneurs and market experts.

Just recently, Tiler joined the Accelerator program at YES!Delft is looking to use that experience on several different fronts. “We have already been able to learn from other companies and gain insights into how to manage a hardware company,” Christiaan says. “We want to learn more about how to manage our supply chain as well as how to raise follow-on funding as a deep tech company.”

To date, the startup has delivered six validation pilots of its products, known as Tiles, with a corresponding smartstand. In March 2022, they launched their commercial solution with a bike rental company at an NH hotel with very promising results. There is another batch of 20 Tiles coming up in May to conduct more promising pilots. It is a time-consuming endeavour so the team will take the coming months to find their market fit with existing customers. “We want to make sure that the customers we currently have are happy and order from us again.” 

Further down the line, they will look into ways to scale up slowly while continuously iterating their product and will be looking for a larger round of follow-on funding starting in 2023.

If you ask Christiaan, the future for Tiler is an exciting one. There is a lot he and his team can achieve in making their solution ever better and smarter. “We will be looking into implementing strict safety procedures for our product,” he says. “We already get a lot of data from the batteries, but our goal for the future would be to collect even more of that data and leverage it in a smart way.”

There are ambitious goals ahead of Tiler and its team, and to make that even more tangible, they say: “We want to have 100,000 tiles by 2027 and be in 100 cities by 2040.” And so the targets have been set, may the hard work continue.
