Marqeta, Inc.

A card-issuing and payment platform that lets other companies build and run their own payment cards through open software interfaces, rather than going through traditional banks. Its technology powers everyday products like the Square business debit card, DoorDash's Dasher card, and Klarna's virtual cards, letting businesses control exactly where, when, and how much a card can be used. Founded in 2010 by Jason Gardner in Oakland, California, it is widely credited as the first open-API card-issuing platform, and its name is a stylized take on "Marqueta," a name with roots meaning "borderland" or "pearl."
