  • History

    de Cavis was founded in January 2009 by Dr. Gonzenbach and Prof. Gauckler as a spin-off of ETH Zurich. Until July 2013, de Cavis was located at the Institute of Non-Metallic Inorganic Materials of ETH Zurich, which enabled a close link between science and practice.

    At the end of June 2013, the company relocated from the laboratories of ETH Zurich to the company’s own technical center in the business incubator glaTec of Empa Dübendorf.

    Today, we still work closely with various institutes of ETH Zurich, EPFL Lausanne and Empa Dübendorf and thus always stay on the pulse of research and development.
