Notarize

Notarize, Inc. operates as Proof, a Boston-based identity verification and digital transaction platform founded in 2015 by Pat Kinsel. The company pioneered remote online notarization - connecting signers to commissioned notaries over live video - and has since expanded into a broader identity network covering eSignature, identity verification, verifiable records, and fraud detection. Proof says its platform secures more than $200 billion in transactions annually across real estate, financial services, insurance, and legal workflows.

Every transaction is bound to a cryptographically verified identity rather than just a signature, producing an identity-assured audit trail; the company issues reusable digital credentials and layers on fraud detection built from 100+ network signals across the transactions it already secures.
