I am JT

I build, invent, tinker, break rules and traditions and want to eventually make the world a better place.

About

Nice to meet you!

I'm an well-organised I-want-to-know-everything geek who strives to change the world using technology.
Started coding as 10yo, created over 100 websites, apps and games for the largest companies in the world.

4 years ago, I have founded Supernova, something that will change the way we do software forever.
Forbes 30 under 30, YCombinator alumni, Startup of the Year 2018 (Czech) & 2016 (Netherlands)

Supernova

Supernova

Supernova is the next-generation tool for designers and developers to make applications faster.
It is the first tool to deliver on a promise of code automation - from design, to code, without developers.

I've founded Supernova over 4 years ago with the vision of making everyone's work much easier.
Developed the core tech, built the team and got Supernova as the first Czech startup to YCombinator.

Currently helming Supernova as CEO/CTO, I am striving to build it into the first Czech unicorn.
We are backed by the world-class investors, EQT and Credo Ventures, raised $2M+ to date.
