Ansa
Ansa is a San Francisco fintech that builds API-first, white-labeled stored-value wallet infrastructure for merchants. It lets brands launch their own branded digital wallet - the Starbucks-app model - where customers pre-load funds and pay in-app, online, or in-store. By batching many small purchases into one funded balance, Ansa cuts card processing fees on low-ticket transactions while adding incentives, loyalty, and analytics on top. Founded in 2022 by Adyen and Affirm alumni Sophia Goldberg and JT Cho, Ansa raised a $14M Series A in April 2024 (about 95% of it from female investors), bringing total funding to roughly $19.4M.
InterPayments
InterPayments is a San Francisco-based fintech that runs surcharging as a managed service. Merchants who accept credit cards get hit with interchange fees; passing those fees back to customers is legal in most of the US and Canada but governed by a patchwork of 70+ jurisdictions and card-network rules. InterPayments handles the calculation, application, and reporting of compliant surcharges, and contractually indemnifies its clients against penalties. It sells through embedded products (PayLink virtual terminal, hosted payment pages), an API, and integrations with platforms like NetSuite and Stripe, serving Fortune 1000 merchants, major banks, and payment processors.
