FRIENDSHIP SYSTEMS is a German software company that started as a spin-off from the Technical University Berlin in 2001. The core team is based in Potsdam, close to Berlin, Germany. Our passionate computer scientists, mathematicians and engineers develop the software system CAESES® and advise and support our customers in creating high-performance products. CAESES® is made for simulation engineers, designers and anyone who is interested in intelligent surface modeling for automated shape optimization. FRIENDSHIP SYSTEMS AG is a stock corporation managed by the company’s founders, Claus Abt and Dr. Stefan Harries.


Our Focus

We help our customers in the field of complex parametric geometry and simulation-driven design processes. In particular, we focus on efficient geometry models and the automation of the geometry generation for design explorations and shape optimization. With many years of experience in the field of flow-related shape optimization and on the basis of our proven software platform CAESES®, we are able to provide solutions to our customers for virtually every challenge that engineers and designers encounter when setting up an optimization process.

We are your partner for variable geometry, CFD process automation and optimization of flow-exposed products.


What Drives Us

Neighbors, friends and family often ask what we do at FRIENDSHIP SYSTEMS. When we say things like “we develop software so that our customers can model and optimize functional surfaces such as ship hulls, turbine blades, turbochargers and piston bowls” we typically get an irritated look.

When we boil it down then to a statement such as “we develop software that is used to cut down emissions and improve energy efficiency” the faces light up a lot.

At FRIENDSHIP SYSTEMS we naturally have asked ourselves what impact our daily effort may have. Hence, we have come up with a conservative estimate of how much CO2 we are saving every year just to get a feeling if it is worthwhile to get up every morning and to spend so many long hours at work.

Well, taking into consideration the maritime industry only, our CAESES® users manage to reduce CO2-emissions by much more than 1 000 000 tons annually. And it is increasing steadily year after year. We think that’s a pretty good outcome, and gives us a strong reason for getting up everyday.

“Our CAESES® users manage to reduce CO2-emissions by much more than 1 000 000 tons annually. This is why we do what we do and this makes me extremely proud of our team and company.”
