Finix is a San Francisco-based payments infrastructure company that gives software platforms, marketplaces, and retailers the tools to own their payments end-to-end. Built around a no-code/low-code PayFac-as-a-Service model and a developer-friendly API, Finix lets SaaS companies monetize payments, manage merchants, and route money across cards, ACH, and wallets without becoming a registered payment facilitator themselves.
Richie Serna is the CEO and co-founder of Finix, a full-stack payments infrastructure company he built from the ground up in San Francisco. A Harvard-educated son of Mexican immigrant parents from Santa Ana, California, Serna left management consulting at Booz & Company, taught himself to code, and joined Balanced - the first payments API for marketplaces - before founding Finix in 2015. Today, Finix has raised $205.5M in total funding (including a $75M Series C in October 2024) and has become a direct-connection payment processor competing with Stripe, Adyen, and Braintree, serving software platforms and marketplaces processing billions of dollars annually.
