Mangopay is a wallet-based payment infrastructure built specifically for organisations with complex, multi-party fund flows. A pioneer in multi-party payments.
Our solution optimises fund flows on behalf of the organisations we work with using wallets as programmable, composable building blocks.
Mangopay’s regulated platform collects payments, secures transactions and holds funds, splits money between the various parties in the funds flow, and ultimately manages the payout to service providers, sellers, and consumers.
Platforms and fintechs using Mangopay regain control and transparency over multi-party payment flows, generate additional revenue, and improve operational efficiency. They can stay compliant while innovating and scaling.
