Presenting the new YES!Delft Accelerator batch

YES!Delft Accelerator Batch 2019

We are presenting the new YES!Delft Accelerator Batch! These startups finished the Accelerator program and are ready to take on the world and beyond. From drones fighting insect infestations in greenhouses to tech reducing noise pollution and the high tech treatment of skeletal misalignment. These seven startups are ready to change the world with their innovative ideas. Come take a closer look at the innovations that soon might be part of your home, or flying high, all the way to Mars.
Gyrafit makes skeletal misalignment treatment easy for all
VideoWindoW - YES!Delft Accelerator
Justin Fourie – Co-Founder Gyrafit

Skeletal misalignment is surprisingly more common than most people think, misalignment in the feet alone affects over 45% of the world population. The feet are the foundation of the entire skeletal structure and if left untreated leads to chronic pain in knees, hips, lower back or legs, and if left untreated increases the chances of getting osteoarthritis in the knees and hip by 55%.

For a truly unique solution, they have combined hardware and AI enabled software to offer a complete solution.

Gyrafits G-Script is a fully adjustable insole orthotic that can correct misalignment in the feet up to 8 degrees and can be adjusted at the point of diagnosis. Their new full body digital measuring and diagnosis booth solution; G-Pod, promises to change the way we access and measure alignment correction, making the treatment available through new, alternate and more accessible sales channels.

The complete treatment solution promises to reduce end-user cost by more than 60% and take the time from diagnosis to treatment application from 2 weeks to under 30 minutes.

Making Gyrafits skeletal misalignment treatment solution; faster, cheaper and simpler.


ARCEON: Trip to the moon and beyond
Rahul Shirke – Founder & Director ARCEON

ARCEON-Novel Elements was established by Rahul Shirke and Bernhard Heidenreich in 2018. We are developing novel and advanced ceramic matrix composite (CMC). Our pilot project will travel to our one and only natural satellite- The Moon. This project allows us to prove the credibility of our innovation. The material is unique because it can withstand a wide range of temperature (from cryogenic to 1600 °C and above) at near zero thermal expansion, high specific strength, corrosion resistance and, most importantly: it is 25% lighter than aluminum alloys. Due to the lack of polymers, it is also stable for long-term in space environment, which is characterized by vacuum and irradiation.

“We believe that our material has tremendous potential, not only in the aerospace but also energy, high-tech, and automobile industry. ARCEON family includes scientific, engineering and business development experts in the field of innovative materials with international experience. Our vision is to push the limits and deliver high-quality novel materials.”

PATS Indoor Drone Solutions: Drones fight golden twin-spot moth in gerbera and chrysanthemum
PATS Indoor Drone Solutions- YES!Delft Accelerator
Bram Tijmons (Co-Founder, CEO)

Flying insects are getting a new and sustainable enemy. The control of insect pests now mainly takes place with the help of (bio) chemical and biological agents. PATS Indoor Drone Solutions, a spin-off from Delft University of Technology, is changing that with small drones that automate pest control and prevention. Through a pilot project aimed at combating the golden twin-spot moth (Chrysodeixis chalcites), a number of innovative gerbera growers are taking advantage of this development to remain at the forefront of sustainable cultivation and cultivation knowledge.

PATS sees its technology not only as a supplement to the current package of resources. In the long term, the system must also reduce substance use for specific pests and it is expected that the grower will have to spend less time scouting and combating pests. 

“The aim is to fully implement the fight against the golden twin-spot moth, for example, using our system, precisely because of the preventive approach we use. In addition, our solution does not conflict with the biological control of other pests through targeted control of the moth itself.”

Bram Tijmons, PATS Indoor Drone Solutions


Smart-Ship sets sail on the maritime market!
Brent Kok (Co-Founder, CFO), Roy Kok (CO-Founder, CEO) & Jelle Tiemensma (CO-Founder, CTO)

Smart-Ship is setting sail to disrupt the maritime market! Through the application of haptic feedback technology, Smart-Ship is aiming to optimize the interaction between man and machine. By making information transfer to the operators of ships faster and more intuitive, safety and sustainability in maritime operations can be improved. Applications range from small fast ships to offshore and dredging operations, tugs and simulations. 


Braindrop: Notre Dame Cathedral could have been saved originally!
Mustafa Torun (Director) & Ugur Kizilkaya (Founder)

“We, as Braindrop BV, Netherlands, June 2019, have released a revolution which avoids new “Notre Dame catastrophes” forever. It is the strongest and 100% nontoxic fire protection chemical agent which makes anything fireproof easily. So strong that one can apply to his hand and put his hand into the fire!

Every 88 seconds one person die because of fires and billions of dollars damage occurs to the global economy every year. We lose lives, environment, and prosperity like monuments.

The main concern of existing flame retardants is their toxic feature and that they destroy slowly even if they stop fires. Our product TNF now is the single best solution which assures these concerns and provides the lifelong durable fire resistance for people, companies, and governments.”

VideowindoW from Vintage to Future
VideoWindoW - YES!Delft Accelerator
Remco Veenbrink (Founder, CEO) & Mark Oudenhoven (Founder, CFO)

Unlike most hardware startups these founders do not have a degree in engineering –one is an artist and the other an economist. All knowledge is self-taught by tactical learning: ‘to know just enough to challenge existing beliefs and rock the status quo on how to approach further development’ thus Remco Veenbrink. Their innovation is based on available parts engineering added with state of the art electronics and algorithms to create a minimum viable product. Mark Oudenhoven: ‘We implement continuous improvement and focus on strategic growth’ Their primary market segment is airports for which they recently contracted Rotterdam The Hague Airport as their launching customer. VideowindoW is a glare control system embedded into the exterior glass that doubles as a transparent video screen. He adds:’ This way glare control can even be a profit driver for airports’. With airports being their focus international expansion is a logical next step.

‘Passengers can enjoy artistic or commercial content and look outside when they focus beyond the glass layer’.

Remco Veenbrink, VideowindoW


DeNoize – “Active Noise Cancelling Headphones – For Buildings”
DeNoize - YES!Delft Accelerator
Aman Jindal (Founder, CEO)

Noise is frequently cited as one of the leading causes of stress in city life. People living near airports and busy roads complain that they can never relax because of the intrusive sound. Their experiences are reflected in higher levels of mental ill-health, and physical problems like high blood pressure, strokes and early onset of cardiovascular diseases.

DeNoize, a complex-tech startup from the YES!Delft claims to have found a better solution. They have developed an active noise cancellation technology for building facades, promising at least 90% additional reduction against the outdoor noise. Their innovation paved their path to the finals of Philips Innovation Awards and a special feature in the BBC’s science podcast, “The Naked Scientist”. The DeNoize team is working hard to commercialize its technology and aims to finish the market-ready product within a year.

The field of Artificial Intelligence (AI) is moving fast and is full of possibilities. Over the duration of Horizon 2020, €2.6 billion have been invested on AI-related areas. Parallel to that is the growing need of trust. Blockchain is fundamentally a technology that enables trust, but developing it comes with great challenges. 

The municipality of The Hague and YES!Delft understand difficulties of getting AI or blockchain technologies to the market. Therefore, we’re joined forces and provide an AI/Blockchain Validation Lab  to offer the right framework for your startup to succeed.


  • WHAT

    The municipality of The Hague and YES!Delft join forces to provide a 10-week AI/Blockchain Validation Lab to help you find your product/market fit and talk to 100+ potential customers. Get access to our ecosystem including the right political connections in The Hague and YES!Delfts startup network.

  • For who

    Startups with at least two committed founders / decision makers looking to focus on the market fit for their AI or Blockchain based solutions

  • Why

    YES!Delft and The Hague understand the opportunity and the challenges that AI or Blockchain technologies bring – bringing together the key ingredients in one environment: a proven startup ecosystem together with the political connections of The Hague, the network of YES!Delft and the links to TU Delft.

The YES!Delft AI/Blockchain Validation Lab really helped us, giving us a structure and peer group for assessing opportunities and priorities. A heavy investment, especially given our travel overhead, but the sharpened focus and market framing has ultimately saved the Ocean Protocol a lot of time and money.

I help startups get the customer perspective. Many of them have these huge dreams – and that’s great! But running a business is not a dream. It’s a lot of hard work of really understanding why customers might consider buying your stuff.
