High Automatisation

We aim for the highest possible automation of our products right from the start. This means that they can not only be operated with little effort, but are also efficiently scalable.

Agile Implementation

We rely on iterative implementation of the products. Solutions are launched as MVP (Minimal Viable Product), in order to have customer feedback flow directly into the further development.

Skin in the Game

We not only invest our time, but also our own capital to implement ideas and products. We are willing to share the risk and success.

Lean Approach

We do not want to reinvent the wheel. We rely on standard solutions and only focus on custom developments once it is justified by the potential.

Focus on internationalisation

We attach great importance to building up our products from the very beginning in such a way that they can be easily ported to new markets. We take into account not only linguistic, but also commercial and legal aspects.

Ready for the API economy

We put the API (interface) at the center of our products. This way, they profit from the collaboration with other exciting products that developers and software providers connect using the API.
