Identity-bound

Tie every signature to a verified human via Certivus. Passport, liveness and AML screening, recorded as proof.

Audit trail as a feature

A timeline you can read, share by URL and export as a signed PDF. The proof is a surface, not a buried download.

Embed in minutes

One component inherits your app's tokens and signs in place. No redirects, no Pactivo branding unless you want it.

For developers

Seven endpoints. One afternoon.

Create an envelope, add signers, capture the signature, receive a webhook. The whole SES surface is a small, predictable REST API.

A small, portable credential — like Apple Pay's badge, but for who signed.

The moat

Most e-signatures prove a click. Pactivo proves a person.

A typed name is easy to dispute. An identity-bound signature carries a verified credential — passport, liveness, AML screen — into the audit trail, where it holds up under scrutiny.
