CesiumAstro was never built for quiet rooms. Founded in 2017 in Austin, Texas by Shey Sabripour, this company came out of the kind of aerospace background where mistakes cost satellites, careers, and sometimes national patience. After more than two decades designing spacecraft at Lockheed Martin and running billion-dollar programs, Shey Sabripour did not start CesiumAstro to chase hype. He started it to industrialize communications in space, to make signals behave when gravity, latency, and geopolitics are all working against you.
That context matters today because on February 1, 2026, CesiumAstro closed a $470 million Series C, and the structure tells the real story. This was not just $270 million in equity led by Trousdale Ventures with Woven Capital, Janus Henderson Investors, Airbus Ventures, Development Bank of Japan Inc., MESH, EDBI, NewSpace Capital, and others leaning in. It also included $200 million in non-dilutive financing anchored by $185 million from the Export-Import Bank of the United States under its Make More in America Initiative, plus a $15 million J.P. Morgan revolving credit facility. Capital like that does not show up for experiments. It shows up for execution.
CesiumAstro builds the nervous system of modern space. Active electronically scanned array communications, software-defined radios, and fully integrated satellite platforms designed, manufactured, and tested in-house. Element, their 700-kilogram integrated satellite platform, is built to move fast and adapt in orbit. Vireo pushes multi-beam Ka-band payloads beyond legacy constraints. Skylark takes phased-array precision into the air and onto the ground. No moving parts, no mechanical hesitation, just software steering physics like a disciplined DJ riding the mix instead of fighting it.
The traction backs it up. More than $100 million in revenue and bookings over a 24-month window, with roughly ninety percent tied to government missions. NASA lunar navigation. Space Development Agency transport layers. Rocket Lab payload selection for eighteen spacecraft. Defense programs that do not tolerate dropped packets or missed deadlines. This is why the company is scaling from roughly 400 employees today toward more than 1,000 globally, with a 270,000-square-foot advanced manufacturing headquarters coming online in Bee Cave, Texas in 2027.
Leadership has stayed technical and tight. Kenneth Smith stepped into the Chief Financial Officer role in 2025 to steer capital with discipline. James Carwell drives engineering with RF depth that spans UHF through Ka-band. Michael Cheung brings product rigor shaped at Raytheon and Northrop Grumman. Chris Trey Pappas III carries revenue with the calm of a Marine who understands consequences. This is not theater. It is signal control.
