Stable Foundations.

We love building products from scratch. Who doesn’t? The excitement of seeing something grow that once was only a rough idea is incomparable. Transforming ideas into stable foundations is what drives us.

Together with our clients and their teams, we work on defining, structuring and building the organizational and technical capabilities necessary to grow into a cutting-edge digital business.

Reinforced Foundations.

We’re not only building products from scratch but also enjoy jumping into legacy systems and crying about how awful the code looks and how terrible the software behaves, in a typical software engineering manner.

But eventually we will improve what needs to be improved and find a solution for any challenge that you can solve with technology. We help make your existing product even better. Always.

WHY 21?

Well, we are nine. And we don’t want to grow larger than 30 people. Why 30? There’s probably a good scientific explanation somewhere. But to be fair, the idea of a thirty man team started with an experiment at Crytek. Since then, 30 was always the magic number for people in one company. We believe that it’s the perfect size to continue to run the company the way we do. Lean, transparent, with purpose while empowering the people in it.

30
