For teams
Records that hold up in an audit.
Stamp contracts, deliverables and evidence with the details your process requires. Build your own stamp types on top of ours, require fields by file type or vault, and connect your systems through the API.
Stamp types you define
Start from the compliance baseline and add requirements: a matter number on every PDF, a client field in one vault, an external ID from the API.
Versioned rules
Every change to a stamp type is a new version. Receipts name the versions they were held to, so old records keep their meaning.
Issue and revoke
Issue a stamped file to a named recipient with its own signed statement, and revoke it with a reason when needed.
API, webhooks and an audit trail
Scoped API keys with idempotent stamping, signed webhooks, and an append-only log of every action.
Questions
- Can we use single sign-on?
- Yes. Sign in with your identity provider through SSO; magic links remain available for guests.
- How do auditors check a record?
- Send the receipt link or the evidence pack. It verifies with OpenSSL and our published public keys.
Your first stamp takes a minute.
