Marqeta 

Headquartered in Oakland, California, and founded in 2010, Marqeta provides its clients with a card-issuing platform that offers the infrastructure and tools necessary to offer digital, physical, and tokenized payment options without the need for a traditional bank. The company's open APIs are designed to allow third parties like DoorDash, Klarna, and Block to rapidly develop and deploy innovative card-based products and payment services without the need to develop the underlying technology. The company generates revenue primarily through processing and ATM fees for cards issued on its platform.
