CAIN-42 CLAWXThe company
FIRME AI CORPORATION
FIRME AI CORPORATION is a technology company based in San Francisco, California. We build CAIN-42, a Byzantine trust fabric for autonomous AI: the layer that decides what AI agents may do, proves what they actually did, and lets anyone verify that proof without trusting us.
What we build
- CAIN-42: the execution boundary for AI agents. Every consequential action (a payment, a database write, a shell command, an MCP tool call) is checked before it runs, and every decision is signed and co-signed by an independent 4-node Byzantine validator quorum.
- PROOFLOOP: finds security bugs in AI-written code, proves each one by running the attack in a sandbox, and proves that a fix holds.
- FALSEWORK: finds fabricated code ("AI slop"): results that are never computed and checks that cannot fail.
- MCPGate: the self-hosted gateway that puts the CAIN-42 boundary in front of your own tools.
How we work
Proof, not promises. Our records are Ed25519-signed, hash-chained and verifiable offline with tools that contain none of our code. Our detection and verification tools are open source under Apache-2.0. Every public claim we make is listed with its evidence on the claims vs evidence page, including what we do not do yet.
