Empowers acquirers and payment providers to connect seamlessly with merchants and their customers MoreLess
Mx51 operates as a fintech firm specializing in providing a white-label Payments-as-a-Service (PaaS) platform. The company's primary clients are banks and acquirers who are seeking to offer modern payment solutions to their merchant customers without the heavy investment in building their own infrastructure from scratch. Mx51's business model is centered on empowering these financial institutions to better compete with new fintech players by offering a more advanced and integrated payment experience to merchants. The company generates revenue by partnering with these banks and acquirers, effectively providing the technology backbone for their merchant payment services.
The company's journey began as an internal project within Assembly Payments, which was later rebranded as Zai. In 2020, Mx51 was spun out as a separate entity, securing a significant A$25 million Series A funding round led by Acorn Capital, with participation from other investors including Westpac's venture capital arm, Reinventure. This strategic move allowed Mx51 to focus exclusively on its PaaS offering. The company was founded by a team with extensive experience in the payments industry, including Victor Zheng, who serves as the CEO. The founding team's background stems from their work at Assembly Payments, where they identified the need for a dedicated platform to help traditional banks bridge the technology gap with nimble fintech startups.
Mx51's core offering is a bank-grade, end-to-end payment platform that seamlessly integrates with merchants' point-of-sale (POS) systems. A key feature is its ability to combine payment solutions with value-added services such as data analytics and customer loyalty programs, which merchants can access directly through their payment terminals. This creates a more holistic business management tool for merchants, going beyond simple transaction processing. For the banks and acquirers, the platform is delivered as a white-label solution, meaning they can brand it as their own. This allows them to maintain their customer relationships while leveraging Mx51's underlying technology. The platform is designed for scalability and aims to provide a more stable and feature-rich alternative to the fragmented solutions that merchants often have to piece together.
