The compliance gap
Regulators & buyers are asking. Most teams can't answer.
Three things break the second an auditor asks to see the evidence.
Proof is non-portable
Compliance claims live in PDFs + Notion pages. Buyers can't verify without your security team on the call.
Frameworks don't align
EU AI Act Article 9, NIST MAP-1.1, and ISO 42001 Clause 6.1 describe the same control. Answering four times doesn't scale.
Audit trails are missing
When a model retrains, the compliance posture moves too. Most teams can't reconstruct what changed, when.
What you get
A full compliance stack. Not a checklist app.
Everything you need to move fast in regulated markets and prove it later.
How it works
Three steps. No spreadsheets.
1
Register your system
Fingerprint your model (SHA-256), declare its intended purpose, and map it to the frameworks it touches. Takes 60 seconds.
2
Issue an attestation
Attestry signs a compliance claim against your evidence bundle. Ed25519 keys. Verifiable independently.
3
Anyone can verify
Share a URL or QR code. Buyers + auditors + regulators check signature validity + revocation status in real time.
Frameworks + security
Covers the rulebook, signs the proof.

For developers
Ship an attestation in six lines.
TypeScript + Python SDKs. An MCP server for Claude Desktop + Cursor. A REST API that returns Ed25519-signed proofs.

No CI plumbing. No compliance-team hand-off. Your deploy pipeline signs the attestation; your registry publishes it; your buyers verify it themselves.

Free plan includes fingerprinting, unverified attestations, and a public registry listing. Upgrade when you need signed proofs or SLA-backed verification.
