Proof

What Proof does

Proof (legally Notarize, Inc., dba Proof.com) is a Boston-based identity-assured transaction management platform founded in 2015 that secures digital transactions through cryptographic identity verification, biometric authentication, remote online notarization, and real-time fraud detection. The platform is anchored by the Proof Engine and organized around core products (Identify, Notarize, Verify, Sign, Certify, Close, Defend, Command Center) and platform capabilities (Digital ID/Persistent Identity, OmniTrust fraud model, EasyLinks), which together compose the Identity Authorization Network — a hybrid system combining 1,800+ live identity agents with an AI-driven fraud model analyzing 100+ network signals. Proof has secured more than $643 billion in cumulative real estate transactions, including $151 billion in 2025 alone, and serves enterprise customers including First American Title, United Wholesale Mortgage, TIAA, Rippling, Liberty Mutual, USAA, Root Insurance, Lightspark, and Florida Agency Network.

The company monetizes through subscription plans, per-transaction fees on Notarize, Sign, Identify, Verify, and Certify services, plus enterprise API-based licensing and integration services. Pricing is quote-based across Business, Title, and Lender tiers with multi-year enterprise contracts, supplemented by a free Trial Access for evaluation. Proof pursues a vertical go-to-market with enterprise field sales targeting real estate, financial services, insurance, hiring and onboarding, legal services, wealth management, and emerging use cases such as AI agent authentication (Know Your Agent). The company has raised approximately $130 million across disclosed funding rounds, including strategic investments from State Farm Ventures (February 2025) and Visa Ventures (November 2025), and holds stacked regulatory certifications (NIST IAL2 by Kantara Initiative, SOC 2, MISMO, WCAG AA, WebTrust) plus FIDO Alliance Sponsor membership.

Geographically, Proof is U.S.-domestic only — services are explicitly limited to U.S.-based transactions requiring a U.S. Social Security Number — though partnerships with Visa and IDEMIA Public Security position the company for future international expansion via partner networks. Leadership is anchored by founder-CEO Pat Kinsel, with Gary Weingarden joining as Chief Privacy Officer in November 2025 to lead global privacy, GRC, and identity standards governance as the company expands into payments and AI-agent authentication standards.

Core offering

Proof sells an identity-centric security platform that combines identity verification, remote online notarization, electronic signature, and AI-driven fraud detection into a single authorization infrastructure for digital transactions. The platform is built on the Proof Engine and serves enterprise customers (title companies, mortgage lenders, banks, credit unions, insurance carriers) that need to cryptographically verify signer identity, prevent deepfake-driven fraud, and produce auditable records. Revenue is generated through subscription plans and per-transaction fees across named products (Identify, Notarize, Verify, Sign, Certify, Close, Defend, Command Center).

Product overview

Proof (operated by Notarize, Inc. dba Proof.com) offers a single unified identity-centric security platform — the Proof℠ platform — built around its Proof Engine and augmented by a suite of core products: Identify (confirm user identity), Notarize (digitally notarize documents), Verify (validate identity over video with deepfake detection), Sign (send documents for signature), Certify (create cryptographically verifiable records), Close (bring real estate closings online), Defend (catch fraud in real time), and Command Center (manage Proof across teams). Platform capabilities layer on top of these products, including Digital ID (verify once, carry identity everywhere), OmniTrust (Proof's fraud detection model), and EasyLinks (one-to-many transaction links). Together the products compose the Identity Authorization Network that secures $200B+ in transactions annually across real estate, financial services, insurance, credit unions, and other regulated industries.
