Mambu's role

Cloud banking platform

Founded in 2015, Stash offers easy and affordable access to a suite of investing and banking services, as well as education and advice on building wealth. The company is headquartered in New York City and has nearly 500 employees.

Stash recently launched its new Stash Core, a new, proprietary infrastructure platform that underpins its services for Americans who bank like investors. This new banking account experience includes access to an upgraded debit card - the first and only of its kind that allows customers to earn stock and invest when they shop.*

Stash selected Mambu's cloud-native banking platform for Stash Core to ensure scalability in the future as it sees increasing demand. Leveraging Mambu's composable architecture approach, the fintech pioneer can build the modern financial products to suit Stash customers' evolving needs.
