Fully reusable rockets — both stages — built the SpaceX-way by SpaceX alumni
HQ: Kent, WA, United States | Founded: 2019 | Employees: ~500 (est.) | Stage: Late Stage VC (~$9B reported, 2026) | Website: https://www.stokespace.com
Stoke Space was founded in 2019 in Kent, Washington by Andy Lapsa and Tom Feldman — Lapsa an 11-year SpaceX veteran who led propulsion development on the Merlin engine line and left convinced the next frontier was full reusability of both rocket stages. While every other SpaceX competitor (Rocket Lab, Relativity, Firefly) pursues partially reusable boosters, Stoke went directly at the unsolved problem: bringing the upper stage home intact. Its solution is technically audacious — a second-stage heat shield that actively cools itself by flowing cryogenic liquid hydrogen through the vehicle's skin during reentry, turning the hottest surface in rocketry into a regenerative cooling system, exhaustively ground-tested per CEO Lapsa.
The Nova rocket reflects the same first-principles thinking: li
