Startup Weekend is all about learning new things, we arranged the best coaches for you to get the most out of your Startup Weekend! Here are the first 5 out of 10 coaches!

Wilbert van der Kamp   

Back in 2014, Wilbert pitched a quite new idea, called Omapost. Omapost started off as an app that made it possible to send your Instagram pictures as analogue postcards to your grandmother. It later on grew quickly, as more people sent cards to their elders. Next to being the founder of Omapost, Wilbert also works for Innovest to find brand new startups that make the world a better place. Wilbert has a lot of great stories to tell and his creative mind is endless. And last but not least, Wilbert has a tremendous passion for food and great foodstories. So if your team is doing anything that has to do with food, ask Wilbert. He knows.

Yvanka Vletter

Yvanka Vletter will be judging you. No, not as a member of the judges, but as the coach who happens to know a lot about law. She has been a lawyer for over ten years, so she is quite experienced. Besides being a lawyer, Yvanka knows a lot about entrepreneurship, since she has been an entrepreneur herself and started her own office. She also happens to be married to Mark Vletter (founder of Voys and Spindle), so she is quite familiar with entrepreneurship and everything that comes with it. Yvanka loves herself a good book and a nice cup of coffee.

Wietze Willem Mulder

Wietze Willem Mulder has been a business journalist for ten years now. He has written a lot of stories on entrepreneurship, investments and inspiring portraits of startups and scale-ups for Sprout, among other things. So he has seen a lot of (starting) companies from the inside and knows what the obstacles are in building/growing a business. Also, he is the co-author of the (Dutch) book How to find an investor? for startups and How to sell your company? for scale-ups.

It will be his first Startup Weekend, but he is super excited! Currently he is coaching one entrepreneur in Groningen to help his business flourish and keep him motivated in making (the right) decisions. As a journalist, he is used to ask critical questions and not take the first answer for granted. With the basics of journalism - why, what, when, where, who and how -  Wietze wants to let the participants really think about their business idea, if there is a market for it and how to get the first customer. But as a coach, he’s always letting the participants make their own decisions.

Jeroen van der Mark

Jeroen van der Mark is a coach and product developer at He has been an entrepreneur for a few years already and is madly obsessed with sports and fitness. Jeroen is a personal trainer and motivates people to find their own strengths and get the full maximum out of themselves. With a background in sociology and a great sense for IT Jeroen will be a very versatile coach that is going to get the full potential out of the teams.

Maurice Beijk

Maurice Beijk believes in not just 3 p’s, but 4 p’s: People, Planet, Profit and in his own words most important: “Passion”. After the passing away of his nine months young daughter, Maurice decided to only do things that matter. Ever since that moment on Maurice started adding value by innovation, entrepreneurship and creativity. From a very young age on Maurice strongly believes in creativity and collaboration as the key to success. Not only his house had a full environmental friendly make-over, but he also co-created the “greenest factory of the Netherlands”. Therefore Maurice’s expertise is versatile. Want to know more about environmental friendly entrepreneurship? Maurice is your man.
