About SWISSto12
SWISSto12 is an EPFL spin-off (founded 2011 by Emile de Rijk with Alessandro Macor and Jean-Philippe Ansermet) that designs and manufactures additively manufactured RF antenna, waveguide and filter products and complete small geostationary satellites. Its HummingSat compact GEO telecom satellite, developed with ESA, targets lower manufacturing and launch costs for regional and sovereign communications, with first launch planned for 2027 and customers including Intelsat and Viasat/Inmarsat. In July 2026 SWISSto12 closed a US$70 million Series C to meet growing multi-orbit demand for its RF products and satellite systems, following earlier Series B equity, UBS working-capital debt and ESA programme support.
