Aerospace supplier SWISSto12 has closed a $70m Series C funding round.
SWISSto12 provides radio frequency products and sub-systems to space firms, enabled by proprietary 3D printing technology. It is said to have more than 1,000 products in orbit and more than 100 sub-systems deployed on aircraft and ships.
This latest round of venture capital funding follows the award of $84.8 million from the European Space Agency (ESA) Member States to the HummingSat ARTES partnership project. HummingSat is a Geostationary (GEO) small satellite programme, through which ESA is supporting the development and in-orbit validation.
SWISSto12 also says that the Series C fundraise follows a period of sustained commercial growth. Last year, it is said to have achieved revenues of $140 million and total contract values exceeding $500 million. EBITDA is said to be positive in 2026.
To date, SWISSto12 has secured seven contracts for its HummingSat GEO small satellite with leading global satellite operators, including SES and Viasat. The company has also expanded its HummingLink multi-orbit payload and antenna solutions business into low Earth orbit (LEO) constellation customer programs and diverse missions across Europe and APAC. Over 2,000 HummingLink solutions are now deployed in orbit across active space missions.
With this new round, the company is scaling its manufacturing and integration capacity to meet accelerating demand from commercial and sovereign government customers. This demand spans HummingLink - advanced, multi-orbit payload solutions - and HummingSat.
Fredrik Gustavsson, Chief Financial and Strategy Officer of SWISSto12, said, “The financial picture at SWISSto12 is robust and primed for global growth. $140 million in revenue for 2025, more than $500 million in customer contracts, and an 110% compound annual growth rate since 2022. These are the signals of an agile business, deploying capital efficiently, and operating at scale in a fast-growing industry. This Series C accelerates us further to meet strong demand from a space, satellite and telecommunications market that’s evolving and growing at pace.”
Emile de Rijk, CEO and founder of SWISSto12, added, “Space is increasingly recognised 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.”
