Safety case evidence that replays the same way twice.
We're a small, senior team building the deterministic evidence layer for autonomous fleet safety cases. FieldSpace populates the behavioral acceptance criteria in the industry-standard safety case framework with per-event evidence that operators, auditors, and underwriters can re-run identically.
What we believe
Sell to the entities carrying the safety liability
AV operators publish safety cases. Insurers underwrite the resulting fleets. Both are budget-owners with a real problem. Tier-1 suppliers offload liability through contracts, which is why a third-party evidence layer was never their budget line.
Determinism is useful because it is reviewable
A safety team, an auditor, and an underwriter should all be able to re-run the same evidence and get the same output. Sampled neural runs cannot. Exact-number-theory determinism can.
Map into the framework that already exists
The Favaro 2023 paper invited third-party evaluative methodologies to populate the behavioral acceptance criteria space. FieldSpace is one of those methodologies, not a replacement for the operator's existing portfolio.
Source review should be available when it matters
For serious safety review, customers need more than a demo. Under NDA, the safety path should be inspectable enough for engineers to challenge assumptions and reproduce results.
Where we came from
FieldSpace started as an internal research programme inside StarDrive, a deep-tech company building physics-grounded infrastructure for space situational awareness and defence autonomy. The same mathematical primitives (partial differential equations solved at wire-speed on commodity silicon) that let us propagate satellite uncertainty turn out to work remarkably well for propagating traffic risk in a driving scene.
We took that kernel and wrapped it in a safety observer, benchmark harnesses, and a closed-loop planner wrapper called FieldSpace. Today the focus is public benchmark evidence, log replay, and narrow partner-selected edge cases.
The team is senior, small, and technical. We've built satellites, fighter-jet avionics, and production driving stacks at companies whose names we can't put on a marketing page. We'd rather ship than brand.
The facts that fit on one page
Short calls. Bring the safety case.
If you're authoring an AV safety case, underwriting an autonomous fleet, or running a safety-case program inside an OEM or Tier-1, we'd like 30 minutes.
