Connect the autonomy stack you already run. Fathom watches the work, clears bounded impasses, and hands judgment to a person when evidence runs out.
Real-time control on the robot. Fathom reasoning in the cloud.




A dropped item, blocked path, or ambiguous scene can stall otherwise capable autonomy.
One human per robot destroys the economics of a growing fleet.
Without decisions, rejections, and outcomes in one record, the same failure returns.
Install the thin Factor Bridge, map your evidence and high-level skills once, and activate one Fathom Instance per robot.
Factor Bridge uses outbound TLS and one credential per robot.
Choose Observe, Assist, or Operate and pin the allowed evidence and skills.
The Bridge reports active work. Factor creates the Shift automatically.
Verity checks the decision contract. Your stack still accepts or rejects every skill.
Reads configured evidence, reasons over impasses, proposes bounded skills, and asks a person when evidence is weak.
Identifies the robot, sends configured evidence, enforces mode and allowlists, invokes approved high-level skills, and reports outcomes.
The Bridge sends evidence. Fathom reasons. No skill is authorized.
Fathom proposes an allowed skill. A person or customer application approves it.
Verity approves the contract. The Bridge and customer stack still validate locally.
Evidence is weak, confidence is low, or the approved recovery set is exhausted.
A person accepts the Handoff. Factor pauses the meter while the person owns it.
The outcome is recorded and responsibility returns to the same pinned Instance revision.
Record Fathom decisions, Verity results, Bridge acceptance, local rejection, and outcomes.
See where multiple robots encountered the same bounded failure pattern.
New instructions or permissions create a new Instance revision. Active Shifts never change silently.
The meter runs while an automatic Shift is active. It pauses while a human owns a Handoff.
Use the signed container or small binary, or implement the same public protocol in your own client.
One robot type and up to five robots. Includes adapter work, skill contracts, Handoff rules, and evidence review.
Fathom stays available. The Bridge opens Shifts automatically when robot work begins.
