Marqeta (MQ)

The company’s open API model is central to its business. Customers can use Marqeta’s tools to design card programs with customized authorization rules, real-time transaction controls, funding options, and data features. This makes the platform attractive to technology-led companies that need flexible payment products, including on-demand delivery platforms, buy-now-pay-later providers, expense management firms, digital banks, and embedded finance applications.

Marqeta does not operate like a traditional bank. Instead, it connects its customers to issuing banks, card networks, processors, and compliance infrastructure through a programmable platform. This position in the payments value chain allows companies such as fintechs and marketplaces to launch card-based products more quickly than they could through legacy systems. Examples of use cases include instant expense cards for workers, virtual cards for supplier payments, and consumer payment cards linked to app-based accounts.

The company generates most of its revenue from activity on cards issued through its platform, including processing-related fees and ATM-related fees. Its performance depends on payment volume, customer concentration, client growth, and the broader adoption of embedded finance. Marqeta operates in a competitive market that includes legacy processors, issuer processors, banking-as-a-service providers, and large payments technology companies.
