Why we invested

Why mx51,
and why then.

Payments infrastructure in Australia is largely controlled by the Big Four. mx51 was spun out of Westpac with a different mandate: to build payments-as-a-service for the rest of the market – banks, fintechs, vertical SaaS.

The team had built the original Westpac merchant platform. The spinout was a once-a-decade opportunity to take that operational muscle to the open market.

We co-led the seed in 2020. mx51 has since become critical payments infrastructure for dozens of Australian fintechs.
