Integrated Space Systems
Satellite platforms and subsystems built as one controlled stack.
Hexeia develops bus architecture, ADCS, power, RF, onboard computing, structures, and integration together from day one.
Satellite Subsystems
Subsystems designed for tighter control in orbit.

Execution Model
From mission definition to orbit, We’ve got you covered.
Hexeia carries the program from concept through design, build, launch readiness, and on-orbit operations without breaking the engineering chain.
Mission Definition
Payload, orbit, lifetime, and data goals are defined together.
Design
Platform and subsystems are architected as one controlled stack.
Build
Hardware, software, and interfaces converge against the same plan.
Test & Clear
Verification, compliance, and launch readiness are closed systematically.
Launch
The satellite is integrated for deployment with operations already in view.
Orbit Ops
Commissioning and sustained operations drive the mission toward usable data.
Operational Data
The output is an active satellite system delivering mission value in orbit.
Project
Under Development
GRIFFIN
Built for intervention in orbit.
Autonomous. Orbital. Built for physical interaction in space. Rendezvous. Capture. Stabilisation. Intervention. All without a cooperative target.
When a satellite loses control, drifts off station, or fails mid-mission, there is currently no way to reach it. GRIFFIN is being built to change that.
GRF-01 // LEO-OPS // STATUS: DEVELOPMENT
GRIFFIN. COMING SOON.
Why Hexeia
Space missions need builders, not another reseller.
We build what we sell. Every subsystem, including power, RF, compute, and structure, is designed in-house, owned by us, and understood end to end. No opaque black boxes. No critical dependencies you cannot see, validate, or control.
01
Owned IP
Every schematic, firmware stack, and structural analysis is developed under our control. What we ship, we own.
02
End-to-End Capability
From individual subsystems to a complete satellite bus. We understand how everything integrates, because we built all of it.
03
Built For Real Missions
Our team brings years of hands-on small satellite development experience. We know what it takes to reach orbit — and what it costs when things fail.
