We are pleased that you are interested in us.

We are also interested in you.

In the work we do, we seek to offer every single customer a solution that is perfect for them – and we’ve been been doing this for 20 years. The will to blaze new trails is in our DNA: we started off as a University of Stuttgart venture that was spun off. To this very day, we continue to work successfully and independently with key players from various market areas as well as with smaller smart pioneers in the industry. Our software is constantly being enhanced and upgraded so that it keeps pace with the fast-changing technology environment and the dynamic energy market. However, our passion remains the same: to find precisely the right solution to meet the needs of every customer – including you, if you would like. It’s a promise!
