Axiom Space

A privately held American company that has flown four crewed private missions to the International Space Station — Ax-1 (2022) through Ax-4 (2025) — carrying commercial and government-sponsored astronauts. Axiom is building Axiom Station, a commercial space station whose first modules attach to the ISS before it becomes free-flying, and it developed the AxEMU spacesuit selected by NASA for the Artemis III landing.

Private company — financial figures are public estimates.
