The story

Fidel API (legal entity Enigmatic Smile Ltd) launched in 2018 as a card-linking infrastructure company giving developers a single API to connect Visa, Mastercard, and Amex transactions to loyalty and rewards experiences. After raising $86M+ through 2022 and expanding to power Google Pay, British Airways, RBC and others, the company has narrowed its product surface to two offerings: the Select Transactions API and Offers as a Service (OaaS), a turnkey card-linked offers platform. LinkedIn data shows headcount contracting to ~16 people (from 35+ at peak), suggesting the business has been restructured under Enigmatic Smile leadership (Bishara Smeir as CEO) into a more focused card-linked-offers infrastructure play.
