Software & game studio
The studio where ideas
cross into shipped products.
We scope, build and ship mobile apps, web apps and games. Senior engineering, short cycles, and code you actually own.

[03]Approach
How we work.
01
Senior-led delivery
The person who scopes your project is the person who builds it. No handoff to a junior bench.
02
Short cycles
Small, frequent releases over big-bang launches. You see working software early and often.
03
Real ownership
Documented, readable code that you — or whoever comes next — can live with. It is yours.
04
Shipped, not demoed
We take it to production: the app stores, the web, the build. Done means live.
[04]Studio
An Altis Koten studio
Kōten is the product studio of Altis Koten, an independent software and AI practice based in Louvain-la-Neuve, Belgium.
We work with small and mid-sized companies, startups and product teams that need a clear scope, a real first release, and an engineering partner who stays accountable.
