Curve

Curve is a London-based fintech, founded in 2015 by Shachar Bialick, that consolidates multiple debit and credit cards into a single smart card and mobile wallet. Its "over-the-top" banking platform lets customers spend from any linked Mastercard or Visa card, switch the funding source of a past purchase up to 120 days later with "Go Back in Time", avoid foreign-exchange fees, earn cashback, and pay in instalments with Curve Flex. Premium tiers (Curve Pay X / Pro / Pro+) add insurance, lounge access, and richer rewards. Curve is backed by Seedcamp and Speedinvest among others. Curve does not publish a public developer API — it acts as an open-banking consumer to aggregate customer account balances rather than exposing a provider API.

Curve is profiled on the APIs.io network. Tagged areas include Company, Fintech, Payments, Digital Wallet, and Cards.

Curve’s developer surface includes support, engineering blog, pricing, and 5 more developer resources.
