SUMTEQ- Historie


SUMTEQ GmbH is a high-tech start-up from Cologne founded in 2014 with the purpose of manufacturing and distributing SUMFOAM® – an innovative, nanoporous high-performance material.

Two of the managing partners of the GmbH are Alexander and Roland. Both founders decided to not only leave the know-how for the production of SUMFOAM® and the underlying promising technology, which they had acquired during their doctorate at the Physical-Chemical Institute of the University of Cologne, as written words in their dissertations, but to develop it further and bring it to market maturity. They were supported by their PhD supervisor and co-founder Prof. Strey. Michael was integrated from day one and complements the founding team with his several years of professional experience in consulting and industry, especially in the areas of finance, strategy and organizational development.

The SUMTEQ team thus consists of goal-oriented, conscientious yet spontaneous lateral thinkers for whom “problems” mean “challenges” and for whom the goal, the solution of the customer’s needs, is the most important thing.
