Originally founded as Wright Express in 1983 as a fleet fuel card company, WEX expanded its core card-issuing and payment-processing capabilities via a series of acquisitions into three distinct verticals: fleet/mobility, travel B2B payments (via eNett/Optal), and employee benefits (HSA/FSA). The company operates WEX Bank (Utah industrial bank charter) to self-fund portions of its credit and card programs. The strategic arc is from closed-loop fleet cards toward a multi-vertical embedded payments infrastructure company providing virtual card issuance, corporate payment processing, and benefits administration to enterprise and SMB customers globally.
