Creativity at the intersection of art & tech.

A working studio of one. I design and build small digital products — most live somewhere between sport, daily life and culture — and play music with Jauza on the side.

(01) About

Built in Helsinki,
one at a time.

Ville-Veikko Järvilehto — software maker, occasional bandmate.

I start every project the same way: something doesn't exist that should, or something exists but isn't quite right for Finland, or for people who care deeply about one specific thing.

The products here are mine — I designed them, built them, and still run them. The pace is deliberate: fast enough to ship before the idea goes cold, slow enough to not throw away good work. I reach for Next.js and Firebase, move quickly with AI tooling, and iterate once real people start using something.

Currently iterating on Kiekkokisa and HyzerMind. On weekends: singing in a cover band somewhere in Helsinki.
