Introducing identity-assured transactions

When trust matters, get Proof
With Proof, we’re introducing a new way to transact. Sign legally binding agreements with strong identification and evidence. Protect your signature from forgery.
When speed matters, sign it
If risk is low, a basic eSignature with Proof is the fastest way to sign on the dotted line.

Lock in Proof, unlock trust
Proof is the only signature platform with Enhanced Signer Identification. It provides evidence about the identity, not just the transaction. It’s enriched with data about a person’s identity, device and location so that you can fully trust their signature.
Block fraud before it starts
Whether a document requires a basic signature or a notarization, Proof monitors fraud risk in every transaction. When a transaction looks suspicious, it’s flagged for your review. With Proof, we’re protecting every transaction from potential forgery.


Smart execution engine
Navigate the ever expanding sea of rules including state laws, regulatory requirements, industry standards, or company policy. Proof simplifies the complexity so you can sign with confidence knowing that it will be accepted. Finally, there’s a platform that does not require you to be an expert in the law.
Signatures that can’t be forged
Proof fuses a verified identity to every signature with a cryptographic seal. This creates a digital signature on every document which can’t be tampered with. Now you can verify who has signed, not only by the signature on the face of the document, but by verifying the unique set of cryptographic bytes for every signature.


Rise to a new standard of trust
Proof is the first organization, approved by the Kantara Initiative to combine IAL2 identity verification with an electronic signature all on one platform. Use Proof for highly regulated use cases where strong identity assurance is required.
