Mambu, a global cloud banking firm, has launched Mambu Payments, a composable banking platform designed to help financial institutions modernize their core infrastructure and accelerate innovation across the entire banking stack. The platform, which integrates seamlessly with any core banking ecosystem, is designed to help financial institutions face regulatory pressure, the rise of instant payments, industry-wide shifts like ISO 20022, and increasing customer expectations for speed and reliability. Mambu connects institutions to a growing network of pre-integrated clearing systems, partner banks, and payment schemes, enabling end-to-end automation through a modern payments hub. The service is gaining traction, with Western Union, INDEXO Bank, and BCB Group all expanding their partnerships with Mambu to modernize their payment systems. Mambu Payments will be officially unveiled at Money20/20 Europe, where the company will showcase its expanded platform and meet with banks, fintechs, and partners shaping the future of finance.
