Entrepreneur in ed-tech, building the future of education as a founder and CEO at Playful.

I write about the future of education, designing learning games, and running a startup.

I'm a generalist, introvert, gamer, and optimizing to be useful.

What I’m working on


I’m a full-time co-founder & CEO @ Playful. We’re building a digital playground where kids become leaders and innovators through gameplay.

Start a Project (course)

I co-run an entrepreneurship seminar at the Charles University in Prague with Jan Vesely where students work on their own projects.


Education + Games + AI

I’m researching projects and best practices on the intersection of education, AI, and games, because those are the tools we’re using at Playful to build the future of education.
