Ready-made software products that we adapt to your processes. A modular business platform — developed and hosted in Germany, faster than custom-built and more flexible than off-the-shelf SaaS. In production with mid-sized companies since 2003.
We are an owner-led IT consultancy with our own solution portfolio. We build on a modern, open stack — from low-code platforms and web frameworks to our own AI agents. We pick the technology to fit your problem, not the other way around.

We work with an open stack: Intrexx as a low-code platform (certified Solution Partner), Hono + Bun + TypeScript for modern APIs, React and Astro on the frontend, the Claude API for AI agents, and our own private cloud in German data centers. Technology follows the problem — not the other way around.
