We started in Melbourne in 2015 to build the infrastructure global commerce runs on. We're the regulated backbone behind global payments: not by accident, but by design. A decade plus, 85+ licenses, and a financial infrastructure spanning North America, Europe, the Middle East, and Asia-Pacific. We're co-headquartered in San Francisco and Singapore, with more than 2,700 people across 27 offices.

We're reimagining how businesses interact with finance from the ground up, AI- and agent-native by default, think agent wallets, agentic bookkeepers, and spend-management autopilots, with APIs designed for agents as first-class users. The hard part is trust: building agent-native systems precise enough to move real money autonomously, on top of a decade of real infrastructure. This is a team for engineers who'd rather own an unsolved problem than inherit a mature one.
