Portal Space Systems raised a $50M Series A to continue building its maneuverable spacecraft.
Geodesic Capital and Mach33 led the round, which also included participation from Booz Allen Ventures, Ark Invest, AlleyCorp, and FUSE.
Why it matters: Customers today don’t just want to get to space—they want to be able to move around once they’re there. That’s where Portal’s Supernova and Starburst spacecraft come in. These spacecraft aim to provide a critical capability for payloads catching a rideshare launch that need to get to a specific orbit—and for companies looking to be good orbital stewards and deorbit at the end of their mission.
Flashback: It’s been almost exactly a year since Portal raised its $17.5M seed round. In that time, Portal has gotten to space for the first time, launching its “Mini-Nova” payload last month aboard SpaceX’s Transporter-16 flight to test systems that will power Portal’s future spacecraft.
What’s next: The WA-based company is working on achieving several milestones, with the Series A funding, including:
- The first flight of Portal’s Starburst spacecraft, set to fly on Transporter-18 in Q4;
- The first flight of its larger Supernova spacecraft, no earlier than 2027;
- Growing Portal’s 40-person staff to 100 employees by the end of 2026. Target areas include all engineering disciplines, as well as manufacturing, sales, business development, supply chain, procurement, product management, and people operations, Portal CEO Jeff Thornburg told Payload.
- Building a 52,000 sq. ft. factory to scale and meet demand.
