Company Overview
About Notarize
Notarize is an online notarization company founded in 2015 by Pat Kinsel and headquartered in Boston, Massachusetts. The company pioneered the Remote Online Notarization (RON) market in the United States, becoming the first company to conduct a legally valid online notarization under Virginia''s landmark RON legislation. Notarize''s platform connects signers with commissioned notaries via live video sessions, integrating digital identity verification, e-signature capture, and tamper-evident audit trails to produce notarized documents that are legally equivalent to in-person notarizations across all 50 states (all of which have now enacted RON legislation or accept out-of-state RON documents).
Business Model & Competitive Advantage
Notarize raised over $130M in total funding, including a $130M Series D in 2021 led by Canapi Ventures with participation from Polaris Partners and existing investors. At the time, the company served hundreds of thousands of users and thousands of enterprise clients across real estate, financial services, legal, and automotive sectors. In 2022, the company rebranded its parent entity to Proof — reflecting a strategic expansion from notarization alone to a broader platform encompassing eSign, digital identity verification, and document workflow automation. The Notarize brand continues to serve consumer and SMB users, while the Proof brand targets enterprise buyers seeking a full identity and document workflow platform.
Competitive Landscape 2025–2026
Proof/Notarize competes with DocuSign (for eSign and identity), Stavvy, OneNotary, and in-person notarization services. Its key advantages are its established notary network (thousands of commissioned, SOC 2-audited notaries available 24/7), its first-mover regulatory relationships (Notarize helped draft and pass RON legislation in multiple states), and the breadth of its document types supported — including real estate closings, loan signings, legal affidavits, and estate planning documents. Real estate is Notarize/Proof''s largest vertical, where the ability to close a mortgage entirely online has become standard in progressive title and lender workflows.
