One Inc

One Inc is a Folsom, California-based digital payments network built exclusively for the insurance industry. Founded in 2012 by former insurance executives Christopher Ewing and Tim Tyannikov, the company unifies premium collection (PremiumPay) and claims disbursement (ClaimsPay) on a single platform purpose-built for carrier workflows.

Footprint. One Inc reports serving 290+ insurance carriers and processing approximately $120 billion in annual premium and claims volume according to its current marketing materials. Named customers drawn from One Inc's own press releases include Arbella Insurance Group (Massachusetts P&C, running both PremiumPay and ClaimsPay), GoAuto Insurance (non-standard auto), Mutual Benefit Group (Pennsylvania P&C, ClaimsPay for outbound disbursements), and The Philadelphia Contributionship — the oldest US property insurer, founded in 1752. The customer base skews toward regional and mid-market P&C carriers rather than the top-tier nationals; we did not find sourced confirmation of Liberty Mutual, AIG, or Farmers as named One Inc carriers in public announcements.

Ownership. Great Hill Partners completed a recapitalization of One Inc in February 2020; financial terms were not disclosed. The frequently-cited "Thomas H. Lee Partners 2022 ~$1B acquisition" narrative is not supported by public sources — the PE sponsor is Great Hill, not THL. In March 2024, Nordic Capital announced a strategic investment joining Great Hill as co-investor, with Great Hill retaining an equal stake and management continuing to hold a significant position; deal value was not disclosed. Earlier venture backers included AXA Venture Partners, MassMutual Ventures, and American Family Ventures, with total pre-Great Hill funding reported above $50M.

Product positioning — the carrier-specific wedge. One Inc's defensible position is insurance-specific workflow depth, not payment processing economics. The platform ships with pre-built integrations to Guidewire, Duck Creek, Majesco, Verisk's FAST life platform, LIDP, and Finys — the policy admin and claims cores carriers already run. ClaimsPay supports push-to-debit, EFT, ACH, Venmo, PayPal, Apple Pay, Google Pay, and paper check fallback, which matters because carriers must disburse to any claimant regardless of technical sophistication, not just opt-in consumers. PremiumPay handles recurring premium billing, installment plans, and NSF/chargeback workflows that generic gateways treat as edge cases.

Competition with Stripe and Adyen. Stripe and Adyen are materially cheaper per-transaction and offer better developer experience, but they treat insurance as a generic merchant category. They do not natively handle claims disbursement (an outbound flow that requires KYC on payees, not payers), they do not integrate with policy admin and claims core systems, and they do not ship with the carrier-specific compliance tooling (state-level unclaimed property rules, check issuance fallback, lien-holder multi-party payee handling) that insurance requires. One Inc's bet is that carriers will pay a premium for vertical depth — and its PE sponsors are betting the same.

Analyst posture. One Inc has commissioned Celent research (most recently the 2025 "Behind the Wheel of Trust" auto claims loyalty study), and Celent maintains a vendor profile on ClaimsPay. One Inc does not yet appear as a ranked vendor in the major Gartner or Forrester payments quadrants, which cover horizontal payment processors rather than insurance-vertical payment networks.

What buyers should expect. Procurement is direct-sales, not self-serve. The platform is US-only with no documented European or UK footprint. Carriers inherit One Inc's banking partner stack (J.P. Morgan Payments, U.S. Bank) rather than running direct processor relationships, and pricing is not publicly disclosed — expect negotiated enterprise contracts tied to volume tiers.
