// data sovereignty

So that software stays here — data sovereignty, not US Cloud.

We build software designed to run in Germany and Europe — GDPR-compliant, data-sovereign. Not because it’s easier. Because our work shouldn’t be steerable overnight from somewhere else.

Most software today depends on US cloud platforms — AWS, Azure, Google Cloud. Code, data, identities — everything flows through infrastructure subject to other legal regimes. If the political weather shifts there, business foundations shift with it.

We build deliberately against that. Every application we ship should still hold up when the licence terms, sanctions or cloud prices of a US provider change overnight. That only works if the whole stack — development, hosting, operations — sits inside German and European law.

// hosting in germany

Own hardware. German data centres. GDPR with no asterisks.

Build servers, mail, CI/CD, internal tools — everything runs on our own hardware that we physically know, or on root servers in German data centres. No hidden outsourcing, no shadow provider. GDPR-compliant by default — not an add-on.

For client projects we use dedicated cloud instances or root servers at German locations such as Falkenstein and Nuremberg, depending on what the project needs. Data sovereignty is in place from the first click.

// location

Software development from Solingen — in the Bergisches Land, the heart of NRW.

Our base camp for software development in NRW sits between Cologne, Düsseldorf and Wuppertal. Solingen has been a craft city for centuries — blades, tools, precision. We carry that into software: well-made, long-lasting, with clear origin.

We work remote-first, but we’re also there in person for clients in Cologne, Düsseldorf, Wuppertal and across the Ruhr region. Meet in person? Happy to. A phone call? Even better.

If that sounds right — write to us.

We’re not the right fit for every project. But if you have an idea that doesn’t slot into a cookie-cutter template, or if you care about software that really belongs to you — then we might be worth a shot. Software development from Solingen, with our own hardware and German hosting — straight from the Bergisches Land.
