Form3 Group Limited

Form3 Group Limited is a UK-based company specializing in cloud-native payment technology that streamlines real-time account-to-account payment processing for financial institutions. Founded in 2016 in London, UK, Form3 Group Limited provides a payment technology platform that supports various payment schemes for banks and payment service providers. The firm was co-founded by David Little, Michael Mueller, and Mike Walters. Form3 offers a comprehensive payment technology platform that facilitates modern, cloud-native, real-time account-to-account payment processing.

Their core products are built on a microservices architecture, designed to provide scalability, adaptability, and resilience for financial institutions. The platform enables users to access various payment schemes, including ACH and real-time payments in the United States, SEPA connectivity in Europe, and various schemes in the UK, such as FPS and BACS. By implementing a single API integration, Form3 allows clients to benefit from a wealth of complementary payment solutions while ensuring data security through strong encryption standards. Their client base includes banks and payment service providers across multiple regions, enabling streamlined banking operations and a reduction in reliance on outdated payment infrastructures.

Form3 generates revenue through a structured model that emphasizes partnerships with financial institutions. The company’s offerings primarily involve subscription-based access to its payment technology platform, enabling clients to process transactions efficiently. For example, a bank utilizing Form3's platform would integrate their API to facilitate ACH and real-time payments for its customers, thereby enhancing its service offerings. Revenue is derived from fees associated with transaction volumes processed through the platform, as well as recurring subscription fees for access to the service.

The firm's flagship services, such as payment orchestration and verification of payee, are central to its revenue generation, providing clients with essential tools to modernize their payment capabilities. In October 2025, Form3 Group Limited raised venture funding from Nationwide Building Society Ventures, which will be used to expand into the US market, accelerate product development, and create a fully integrated payments platform. The company is also designing new products aimed at enhancing their service offerings, with plans for expansion into new geographic regions being a focal point of their growth strategy.
