Unit processes over $100B in annual transaction volume, serves 2M+ accounts, and handles 11M+ API calls daily for category-defining companies including Wix, Highbeam, Wayflyer and Relay.

Today, leading technology companies use Unit to create smarter money experiences, deepen customer relationships, and unlock new revenue. We’re building the infrastructure that will make financial products a native part of software, and we’re looking for people who want to help shape what comes next.
