Modern card issuing platform for building customized payment cards. Oakland CA, publicly traded (MQ), processes $170B+ in payment volume annually for Block, DoorDash, and Affirm.
Marqeta is a modern card issuing platform that enables companies to create, issue, and manage customized payment card programs. Founded in 2010 and headquartered in Oakland, California, Marqeta went public on NASDAQ in 2021 under the ticker MQ. The company processes more than $170 billion in total payment volume annually and counts major technology and fintech companies including Block (formerly Square), DoorDash, Affirm, and Goldman Sachs among its customers.\n\nMarqeta's open API platform gives customers fine-grained control over card authorization logic — a capability it pioneered called Just-in-Time (JIT) funding. Rather than pre-loading a fixed balance onto a card, JIT funding allows the card issuer to make a real-time decision about whether to approve each transaction and how much to fund at the moment of authorization. This capability enables use cases like expense management cards that only work at approved merchants, installment payment cards that draw from loan credit in real time, and delivery driver cards that fund only when a courier has a specific delivery in progress.\n\nMarqeta serves a diverse range of card issuing use cases including buy now pay later card programs, corporate expense cards, disbursement cards, and digital wallets. The company's global issuing capabilities cover multiple currencies and payment networks across North America, Europe, and Asia-Pacific. Post-IPO, Marqeta has continued expanding its platform with token management, fraud controls, and card lifecycle management tools that enterprise issuers need for large-scale card programs.
