Startup Play

Do you have a cool idea for your own business? How scary, risky and ambitious this plan may sound… Give it a chance! Discover the potential of your idea and whether it connects with potential customers during this Startup Play validation program.

Within the program the focus is on interactive sessions as well as 1-on-1 coaching. We think it’s important that you take your idea, but also certainly yourself as an entrepreneur, seriously. And we’ll help you do that.

  • You will work on your business model and learn how to create a pitch deck.
  • Finally, you will learn to experiment and assess the results. In addition, you will work with entrepreneurial tools within the Design Thinking Method.

The Startup Play sessions

So, Startup Play consists of two different parts: the personal coaching and the interactive sessions.

You will receive coaching from our experienced coaches and Activation Managers Micha Heilman or Sander Kuin. During these sessions, you will receive the guidance you need to get the most out of the program. We go deeper into your idea, figure out the “why,” but also ask the right questions for your personal development.

There are a total of 5 interactive sessions to make your idea concrete. So you work on issues and look together with the other participants at what you encounter and how you work on (entrepreneurship) problems. This way you learn from each other and help each other. After each session, join us for the best networking drinks in Leiden!
