We believe that businesses of all sizes deserve better financial and payment products and services. Traditionally, businesses of all sizes are let down by slow applications, protracted onboarding, opaque pricing, restrictive contracts and forced to use outdated solutions that no longer meet the innovative requirements of modern business.

We started our journey four years ago, and have since helped tens of thousands of Australian businesses reduce the complexity and time taken to take and make payments, manage complex fleets of payment hardware, store and save money and lead the conversation in business-to-business fintech. We’re now taking our next steps in expanding our industry and world leading capabilities into the United Kingdom.

Our company is backed by leading global VCs, and brings together experienced payment and tech industry professionals who are aiming to redefine business banking and the way businesses get paid by their customers.
