Verifiable Agent Execution.
One question decides whether an enterprise can deploy an AI agent: can you reproduce what it did, prove it cryptographically, and block any unverified change — in your own perimeter, across any model? That standard has a name, and Runback is built to it.
The six properties.
Re-run any decision exactly — offline, byte-exact, no model calls.
A signed record whose digest the run must reproduce. Verify it, don't just read it.
Any agent, any language, one base-URL change. No SDK, no support.
Block any agent change that doesn't reproduce the audited baseline, in CI.
Self-host. Data and prompts never leave your environment.
Governs whatever you run — GPT, Claude, Gemini, or your own.
We don't compete on models. We own the layer above them.
The model labs win on models — and ship evals and tracing. None ship the verification layer, and they're structurally disincentivized to: it commoditizes the model and keeps your data out of their cloud.
Honest by design — the labs get every ✓ they've earned. The bottom rows are the standard, and only one column holds them.
Hold your agents to the standard.
