Innovate,
don’t imitate.
We develop custom tools that can be tightly integrated into your existing tool chains. That’s why you came here, but how we do it is why our customers stay for the long term.
Advising.
Shaping.
Integrating.
Pioneering is our default
What drives us is our curiosity about unknown territory. Thatʼs why weʼre not satisfied with merely staying up to date about technologies in our field. We also develop tomorrowʼs solutions ourselves.

Our code is open source
All of our tools and frameworks are open source. For us, this means that we can proactively pursue exciting topics and we also benefit from the contributions of the community. For you this means: Bye bye license fees and hello, full transparency!

We don’t believe in one-size-fits-all solutions
Ironically, thatʼs why all our projects start the same way: with listening. What we like best is to get a thorough insight into the problems and challenges that brought you to us.
Bullshit is not part of our vocabulary

This saves us time, which we are happy to invest in making our cooperation with you as pleasant as possible. And speaking of honesty: We hope you see it the same way.
