Satellites
We build the brain that goes on any satellite — onboard AI that spots a non-cooperative approach, and propulsion that manoeuvres away. Decided in orbit, in seconds.
The brain leads.
The legs follow.
Buddy
The onboard AI engine that makes autonomous decisions and delivers real-time intelligence from orbit — no ground loop. It commands propulsion through a safety-bounded interface: our own thruster, or any third-party thruster a satellite already carries.

A water-electrolysis pulsed micro-arcjet — the first thruster designed for Buddy's command interface. Non-toxic, launch-safe, and ten times the thrust of electric thrusters in the same 1U volume.

Two uncrowded niches.
The window is open in 2026.
Edge AI is flight-ready
Radiation-tolerant edge compute now runs live AI on orbit. The hardware risk is retired — autonomy is a software problem now.
Propulsion is breaking
Xenon demand outpaces supply and hydrazine is being phased out. Operators need a safe, scalable alternative. Water is it.
Orbit is contested
Adversarial proximity operations are rising and most satellites cannot see or move. The window to solve both is open now.
