About Us

Spaceium is the missing link in the space industry

We are building a network of fully automated refueling stations in orbit and OpenPort™, the open standard interface that connects them to every spacecraft.

Spaceium Inc. is a Y Combinator company (S24).

MISSION

Make fuel available wherever spacecraft need it, so missions are not limited by the size of the fuel tank.

How we work

Bold mission
We are building infrastructure the industry has never had, and setting the standard others will build on.
Relentless innovation
We design and build our own hardware in house, from the port to the robotic arms that operate it.
Fast execution
We iterate quickly, test early, and fly.

Team

Our founders are aerospace and mechanical engineers who have designed rocket engines, developed recovery systems, and managed payload integrations.
