About Floor IO SA

Floor IO SA is a software engineering company based in Switzerland. We design and build high-performance, production-grade software for the web and mobile.

What We Do

We build full-stack platforms — from infrastructure and APIs to user-facing applications across web, iOS, Android, and desktop. Our work spans real-time systems, content platforms, open-source libraries, and AI-powered tooling.

For every project, we assemble a dedicated engineering team with competences tailored to the specific domain and technical challenges. We leverage AI agents as integral members of these teams — autonomous engineers that handle code generation, testing, translation, data processing, and infrastructure tasks alongside human developers. This approach lets a small team deliver at the scale and velocity of a much larger organization.
