The best components & subsystems space startups
8 components & subsystems companies in the directory, ranked by disclosed funding ($62.6M raised between them), spanning 3 countries.
Nothing flies without the parts. Deployable structures, radiation-hardened processors, shielding, precision timing and the antennas that go on top. These are the suppliers whose names never make the mission patch, but whose hardware is aboard a good share of the spacecraft in this directory.

State of the sector
As of 27 September 2026
The companies here make the parts that are hard to buy. Oxford Space Systems makes antennas that unfold in orbit. Akash Systems builds chips cooled with diamond. TimeTag.Space makes timing hardware for lidar and altimetry, and Ramon.Space makes processors for spacecraft.
Oxford Space Systems' Wrapped Rib antenna deployed in orbit for the first time in January 2026, on SSTL's CarbSAR mission. Akash's diamond cooling also sells on the ground: in February 2026 it delivered its first diamond-cooled Nvidia GPU servers. Beyond Reach Labs unveiled its Flarewing solar arrays in August 2026.
Space Talos, which worked on shielding satellite electronics from radiation, was dissolved in 2024.
