[ ABOUT · XE4 ]

We're keeping orbit navigable.

Xe4 builds the autonomous traffic layer for the new orbital economy. Photon - our flagship product - turns the manual, stressful scramble of collision avoidance into a calm, automated workflow any operator can afford.

[ OUR MISSION ]

Low Earth orbit is getting crowded. Fast.

Tens of thousands of satellites are launching this decade. The math of keeping them from colliding has, until now, meant overnight analysts, bespoke ground software, and budgets only the largest operators could carry.

We started Xe4 to change that. Photon runs the entire conjunction-assessment loop - ingest, analyze, alert, maneuver - as software, so a two-person cubesat team and a national constellation operator get the same protection. Safety in orbit shouldn't be a luxury good.

[ WHAT WE BELIEVE ]

Principles we fly by

Humans stay in the loop

Photon does the analysis and proposes the burn - an operator always approves before anything is commanded. Automation that earns trust, not replaces judgment.

Built on open data

Public catalogs and commercial feeds, fused and reconciled - no proprietary lock-in, no new hardware on the ground or in the sky.

$

Accessible to everyone

Pricing that scales with the fleet you fly. The smallest mission deserves the same collision avoidance as the largest constellation.

Fly with us.

Whether you're launching your first cubesat or operating a constellation, Photon has your back. Let's keep orbit safe together.
