Prove started out life as Payfone
Prove
The 2015 pivot turned a hard consumer payments problem into a cleaner enterprise data business. Instead of trying to get people and merchants to adopt a new way to pay, Prove used the same core asset, a phone number linked identity graph built with carrier, bureau, and third party data, to help banks and fintechs fill forms, check fraud risk, and verify returning users inside existing onboarding flows.

The key carryover from Payfone was not payments volume, it was mobile identity infrastructure. By 2015, the company was already positioning itself around mobile identity authentication, and later described the business as charging companies for access to a phone keyed identity database and related authentication APIs.

The pivot also changed the revenue model. Payments is transaction and acceptance driven, while Prove sells software and data into regulated onboarding workflows. Customers use Pre-Fill to auto complete sign up fields, Identity Manager to refresh CRM records, and MFA tools to verify logins, which creates more predictable recurring revenue.

This put Prove in a different competitive set. Instead of fighting Stripe, card networks, and wallets for checkout share, it now competes with identity and fraud vendors like Socure, Trulioo, Kount, TeleSign, and ID.me, each with different strengths in documents, consortium data, government assurance, or phone based signals.
The next phase is building from phone based verification into a broader trust layer for digital transactions. Newer products like Unified Authentication, Verified Agent, and ProveX extend the original pivot, moving Prove from helping fill out forms and send OTPs toward continuously recognizing users, verifying software agents, and brokering trusted identity data across partners.
