Swiss satellite and payload producer SWISSto12 has raised $70 million from undisclosed investors. The fresh Series C round follows $84.8 million in funding raised in January from European Space Agency (ESA) member states.
- Founded in 2011 and headquartered in Renens, SWISSto12 uses technologies, including 3D printing, to manufacture satellite payloads and antenna systems.
- The company's offering includes two product lines: HummingSat, a compact geostationary satellite platform, and HummingLink, a range of antennas and payload solutions designed for missions across multiple orbits.
- SWISSto12 technologies are being used across direct-to-device connectivity, media broadcasting, intersatellite data relays, and sovereign communications infrastructure.
- To date, the firm has signed seven contracts for HummingSat satellites with operators, including SES and Viasat. Its HummingLink business has also expanded into low Earth orbit constellation programmes and other missions across Europe and the Asia-Pacific region, with more than 2,000 of its solutions currently deployed in orbit.
- SWISSto12 says it has recorded a 110% compound annual growth rate since 2022, generated $140 million in revenue in 2025, and secured contracts worth more than $500 million.
- The fresh capital will allow the company to expand its manufacturing and integration capacity amid growing demand from commercial operators and government customers.
