About The Company
Astranis builds low-cost satellites for high orbits.
Our first product, MicroGEO, offers the world’s lowest-cost satellite broadband. Operating in geostationary orbit, each MicroGEO satellite can provide dedicated satellites to small and medium-sized countries, Fortune 1000 companies, and other commercial customers. Astranis has built a $1 billion backlog for 12+ MicroGEO satellites launching over the next two years.
Astranis also offers services across orbits and use cases. With contracts in place with Space Force, NASA, and other government partners, Astranis is working across MEO and GEO to support government science, PNT, and communications missions.
Astranis has raised $750 million from top global investors and employs a team of over 400 engineers and builders, headquartered at Historic Pier 70 in San Francisco, California.
