Overview
Astranis Space Technologies Corp. designs, manufactures, and operates small geostationary (GEO) communications satellites, branded MicroGEO, aimed at delivering dedicated broadband connectivity, government communications, and positioning/navigation/timing services from high orbit at a fraction of the size and cost of traditional GEO spacecraft.
Founded in San Francisco in October 2015 by John Gedmark and Ryan McLinko and incubated through Y Combinator's Winter 2016 cohort, the company has since launched five GEO satellites -- including the Arcturus/Aurora 4A MicroGEO in 2023 and a four-satellite Block 2 constellation in December 2024 -- with more than ten additional satellites under contract, which the company says represents over $1 billion in satellite services sold.
Commercial customers include Pacific Dataport (Alaska), Anuvu (maritime and aviation connectivity), Apco Networks (Mexico), Thaicom (Thailand), Orbith (Argentina), Chunghwa Telecom (Taiwan), and stc group (Saudi Arabia); Astranis has also expanded into U.S. national-security work, including a Resilient GPS satellite development contract and, as of August 2025, selection as prime contractor for the U.S. Space Force's Protected Tactical SATCOM Global (PTS-G) program.
Astranis has disclosed at least four equity financing events: a $13.5 million Series A in March 2018, a $250 million growth round in April 2021 led by BlackRock with participation from Venrock and Andreessen Horowitz, a $200 million Series D in June 2024 led by a16z Growth Fund and BAM Elevate (which the company said brought its total capital raised to $750 million), and a $300 million Series E in May 2026 co-led by Snowpoint Ventures and Franklin Templeton. That Series E was announced alongside a separate Trinity Capital delayed-draw debt facility of up to $155 million to support new manufacturing capacity -- bringing the combined announcement to $450 million, though only $300M of that is new primary equity. The company's own May 2026 announcement states cumulative funding to date exceeds $1.2 billion, modestly higher than the roughly $763.5 million in individually itemized equity rounds above -- indicating one or more additional financing events (or a larger, undisclosed portion of an existing round) that could not be individually verified via the sources available this session.
Private securities are speculative, illiquid, and involve risk of complete loss of principal. You should be prepared to hold private securities for an extended period; there is no assurance of a secondary market, an IPO, or other liquidity event. You are fully responsible for conducting your own due diligence. Pricing is indicative — nothing here is an offer of securities.
