Darker bar: ahead of the other company on that measure.
Impulse Space is a US in-space-mobility company (founded by SpaceX's Tom Mueller) whose Mira orbital transfer vehicles have flown commercially since 2023, with a Helios high-energy kick stage (GEO-direct) in development, and it supplies Vast's Haven-1 propulsion. It was admitted to NSSL Phase 3 Lane 1 in July 2026 (a first for orbital transportation), making it the in-space mobility category leader. Revenue is estimated at 10-100m (a $500M raise in 2026).

Starfish Space builds autonomous spacecraft tugs for in-orbit docking, satellite servicing and life extension, flown on U.S. Space Force missions.
Darker bar: ahead of the other company on that measure.
Starfish Space is a US satellite-servicing company (ex-Blue Origin founders) with three demonstration missions flown (Otter Pup 1 and 2 RPO, and Remora with Impulse, a December 2025 autonomous approach to ~1,250m with no human in the loop), and its first operational Otters launching in 2026 for SES, NASA, and the US Space Force. It holds the servicing category's contract stack: a $52.5M SDA award (January 2026, the first-ever contracted end-of-life disposal for a LEO constellation), a $54.5M USSF GEO vehicle, and an Intelsat life-extension contract, though it has not yet performed a commercial docking. It raised a $110M Series B (April 2026, Point72-led, >$150M total).
