About us


FRIENDSHIP SYSTEMS is a German software company with the core team being based in Potsdam, Germany. Our passionate team develops the software CAESES® and CAESES® Free, which target simulation engineers (mainly CFD) but also anyone who is interested in intelligent surface design for automated design explorations and shape optimization. The core competence of the company is simulation-ready and variable CAD for complex free form surfaces.

FRIENDSHIP SYSTEMS is managed by Claus Abt and Dr. Stefan Harries, both are founders of the company. The company was founded in 2001 as a spin-off from the Technische Universität Berlin (Technical University Berlin, TUB) and its division Naval Architecture and Ocean Engineering at the Institute of Land and Sea Transport Systems (ILS). Offering software solutions and design consultancy, the company transformed from the German legal entity GbR to GmbH in 2003. In 2007 the consultancy branch was excluded and became FRIENDSHIP CONSULTING (now part of DNV GL Maritime Advisory). Software development and support services remained core businesses of FRIENDSHIP SYSTEMS. The company merged with GL Group, now DNV GL, in 2009, and had been part of DNV GL until beginning of 2015. As of 29th of January 2015, the company is an independent stock corporation, called FRIENDSHIP SYSTEMS AG.
