Satellite firm Swissto12 has secured new funding for its microGEO satellites.

The company this week announced the close of its $70 million Series C funding round.

The funding will be used to scale manufacturing and integration capacity to “meet accelerating demand from commercial and sovereign government customers.”

Emile de Rijk, CEO and founder of Swissto12, said: “Space is increasingly recognized as essential infrastructure for the global economy. In this expanding market, our solutions across payload and satellite lines are creating significant new opportunities for customers. Our products are supporting exciting new customer missions – from direct-to-device connectivity to media broadcasting, intersatellite data relays or sovereign communications infrastructure – many of which span multiple orbits. This Series C funding round accelerates our ability to execute on this growing demand across any payload, any platform and any orbit.”

MicroGeo satellites are craft in geostationary orbits that are much smaller than traditional machines at such high orbits. Comparable microGEO solutions include Boeing’s 702X and ESA’s SGEO missions with Hispasat 36W-1, as well as Astranis’ satellite offerings.

A spin-out from the Swiss Federal Institute of Technology in Lausanne (EPFL) founded in 2011, Swissto12 claims its HummingSat can be up to ten times cheaper than other GEO satellites. The machines measure around 1.5 cubic meters (52.9 cubic feet), loosely half the size of a small car, with 1,000kg (2,204 pounds) of launch mass and able to support 200kg (440.9 pounds) of payload capacity, supplied with 2kW of power with a predicted operational life of 15 years.

Swissto12 has secured seven contracts for its HummingSat geostationary (GEO) satellites, with customers including SES and Viasat, as well as Astrium and Space Compass.

The company said it posted revenues of $140 million (€121 million) for 2025 and total contract values now exceeding $500 million (€432 million), driving positive EBITDA in 2026.

The company has raised more than $200 million to date. Investors include Swisscom Ventures, UBS, Zürcher Kantonal Bank, Venture Kick, and the European Space Agency.
