Our mission at Fidel API is to unlock the full potential of payment cards. We offer a suite of financial infrastructure APIs that enable developers to build programmable experiences connected to purchases made in real-time using a card. Our tools are transforming how merchants and users interact by powering real-time, event-driven engagements, best-in-class loyalty and rewards programs and revolutionizing processes from reimbursements to expense management.
Our APIs are used by start-ups through global enterprises including Google, British Airways, TopCashback, Perkbox, Royal Bank of Canada, and Blackhawk Networks, and are supported by the world’s largest card networks, including Visa, Mastercard and American Express.
Launched in 2018, Fidel is headquartered in London, with offices in Lisbon, New York, and remote employees globally. Fidel is backed by investors including Nyca Partners, QED Investors, Citi Ventures, RBC Capital and Commerce Ventures.
