Sign-off-ready repair decisions for FAA-regulated parts.
A cobot scans the damaged part. The digital twin simulates the repair. Side by side, in real time.
Sign-off-ready repair decisions for FAA-regulated parts.
Aerospace and defense shops scrap hundreds of millions of dollars in repairable parts every year — not because the physics doesn't work, but because a senior engineer's signature is the bottleneck. reFAB scans the damaged part, decides whether and how to repair it, simulates the result on a digital twin, and outputs a regulator-ready audit package. We start with engine airfoils on commercial aero engines.
A trillion-dollar asset base, repaired by hand and by memory.
Today, whether a damaged turbine blade, structural casting or rotating component comes back into service depends almost entirely on the judgment of a small number of senior repair engineers. They look at the part. They decide. They sign. The institutional knowledge lives in their heads — and it is walking out the door.
The decision layer between the scan and the robot.
reFAB takes a 3D scan of a damaged part and outputs the full repair package: the recommended approach, a simulated repair on the digital twin, the toolpath ready to run on the robot, and an audit-ready report keyed to OEM, FAA and DoD repair standards.
It is not a CAM tool, a vision system, or an inspection platform — it is the adjudication and documentation layer that ties them together, so shops can confidently say yes, this can be repaired, here is how, and here is the evidence.
From damaged part to signed repair package — end to end.
A cobot equipped with an Intel RealSense camera scans a mock damaged part. reFAB generates the repair toolpath, simulates the result on the digital twin, and the cobot executes the repair. No human in the loop, no narration — just the pipeline running.

The cost curves crossed.
Repair is the wedge. Re-fabricate is the platform.
The same decision engine that signs off a repair also signs off a re-fabricate, then a new-part build, and eventually any high-value geometry produced by an automated process. Repair earns us the regulatory primitives, the part-class libraries, and the shop relationships. The rest is distribution.
Aerospace MRO first, by part class — not by customer.
We focus on part classes where a single repair decision is worth six figures and a single mistake is worth a grounded fleet. Adjacent markets unlock once the decision engine is validated.

We're raising pre-seed and signing design partners.
If you fund deep-tech or physical-AI at the pre-seed stage — or if you run repair operations at an aerospace, defense or energy shop — we'd like to meet. Pick whichever surface works for you.
