The "MoneyForward Cloud" is the core business of MoneyForward, which is a B2B SaaS.
"Cloud Accounting," the first product in this cloud series, has been released for over a decade and currently boasts hundreds of thousands of users.

As a result of this extended period, there has been an accumulation of technical debt, and certain areas of the architecture remain unsettled. To address these challenges, the Architect department was established in July 2023.

The mission of the Architect department is to improve the architecture of the product, smooth the development process, and enhance the developer's development experience.
