ABOUT ME
GAME DEVELOPER. PROGRAMMER. ENTREPRENEUR.
My background is in the Finnish "demo scene". That's how I learned how to code. In the early 90s, I was one of Finland's first professional game developers. It's now over 30 years since my first game was released so I guess I can be considered a veteran game maker. Click here to read my full history as a game developer.
I was born in Finland. During my life, I have lived in the USA, China, Switzerland, and for a while even in Singapore. The longest time I've lived in one place as an adult has been in my favorite city - Las Vegas, Nevada. Currently, I live in Austin, Texas with my wife and kids.
I am CEO and co-founder of Bitmagic. We're building a platform that allows anyone to create games by just saying what kind of game they'd like to play! It's the most advanced generative AI system in the world, and by far the most excitng project I've ever worked on!
My previous startup was called Utopos Games, an indie studio focused on retro-style games based on learning AI. While Utopos is currently not actively developing its original IP, it pioneered the use of AI learning in games and maybe we'll find a way to bring it back one day...
My latest indie game Guntech 2 was released in 2022 for Nintendo Switch (previously for PC, Xbox and Atari VCS).

GPT-6 Astra plus the Bitmagic GDK feels like the new gold standard for making games — full control, results that actually play well, and when you're done you just say "Publish this" and it's live for everyone.
May 1, 2026Some musings about the state of the AI prompted games today
Saw Ollie Scheers prompt a Destruction Derby clone across the major LLMs, so I ran the same prompt through Bitmagic — then kept going: tweaked car handling, added night racing, dropped in objects, and shared a playable link. That's where the real fun starts.
April 22, 2026Bitmagic's Recursive AI Engine Improves Itself
Our AI agents know when they're working around a missing API to get the job done — and now they propose the engine improvements to fix it. Prompt something today that doesn't quite work, and tomorrow it might, because the engine improved itself overnight.
