Overview At Money Forward, we are dedicated to transforming financial services using advanced technology. With over 50 services for individuals and businesses, including popular products like Money Forward ME and Money Forward Cloud, we help make managing money easier. We use cutting-edge “account aggregation” technology to gather user data, turning it into useful insights for our customers. Within the Money Forward Business Segment (MFBS), Money Forward Cloud is a component-based cloud ERP composed of multiple service groups. While these groups provide flexibility for users to choose combinations based on their needs, developing them in isolation can lead to data silos, inconsistent user experiences, and reduced development efficiency. To solve this, our Platform Product Division (PPD) builds the common foundations that unify these services and ensures their stable use across the company. Our division is responsible for developing and managing shared microservices and backend systems that power workflows and platform functionality across Money Forward Cloud. We work to standardize services, improve collaboration across products, and enhance performance and scalability. By organizing complex system logic, addressing technical debt, and documenting our knowledge, we aim to create a reliable, maintainable, and future-ready platform that delivers consistent value for both developers and end-users.
