Your new team: Moriarty

Team Moriarty cultivates a few healthy habits that even a shared weakness for stone-baked dishes can't harm! In an agile working environment, openness, a love of change and respect nourish the members just as much as nerf guns, banter and anti-stress basketball hoops. With their sleeves rolled up and a mischievous smile on their lips, Moriarty's motto is: wait and see no, drink tea yes!

Why Moriarty?

The brain in high gear, the eagle eye alert, the nose in the wind: that's how we know the master detective Sherlock Holmes. And as passionate problem solvers, we can identify with his spirit. Because we think that bulky software and tools are just as bad as unsuitable methods and outdated ways of thinking! That's why our teams - as well as Moriarty – bear names from the world of Sherlock Holmes.

We are living a specific culture. It is a prerequisite for the way we are organised and the way we work.
