Quantum Space is developing Ranger and Scout spacecraft for multi-orbit operations, on-orbit refueling, and propellant transfer to satellites in GEO.
Darker bar: ahead of the other company on that measure.
Quantum Space — co-founded by former acting NASA administrator Steve Jurczyk with Kam Ghaffarian IBX orbit — builds Ranger, a large maneuverable spacecraft platform for orbital mobility and space-defense missions, with a first flight targeted mid-2026 and explicit positioning toward cislunar operations and the Golden Dome-era defense market. It acquired electric-propulsion maker Phase Four (September 2025), bringing thrusters in-house, and announced in June 2026 it is going public via SPAC at a ~$1.2B valuation — capital and visibility well ahead of flight heritage. It is the most firepower-heavy pre-flight company in this batch.

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).
