Proof

Proof is an identity-centric security platform where every action, from documents signed to actions an AI agent takes, is tied to a verified identity and sealed at the moment it happens.

Making identity the foundation rather than the signature is the meaningful architectural choice. A signature proves a document was signed; it does not prove who signed it, and the fraud in remote transactions happens at the identity step rather than the signing step. Binding the signature to a verified signer and then sealing it means the signing cannot be repudiated afterwards.

The scope extends well past notarization. Account openings, payments and logins are tied to a real human rather than a stolen or synthetic credential, and synthetic identity is now the fastest growing fraud category precisely because it defeats systems checking documents rather than people.

The most forward looking capability addresses AI agents: every action an agent takes on someone's behalf is authorized and traceable straight back to that person. As agents begin transacting autonomously, the question of who authorised a given action becomes both a legal and a practical problem, and almost nobody else in this category has addressed it yet. A cloud wallet recognises users who have already verified, giving repeat signers a frictionless experience rather than repeating identity checks. Pricing is published from 4 dollars.
