Case Study: Money Forward achieves faster development and one-day onboarding with Claude Code

Money Forward builds an AI-native engineering organization with Claude Code

Money Forward, one of Japan's largest cloud-based financial software companies, faced limitations with existing AI coding tools that could not understand the full context across their diverse code repositories and languages. Their challenge was to boost engineering productivity at scale, which led them to launch an internal initiative to find a superior solution, ultimately evaluating the vendor Claude and its product, Claude Code.

By implementing Claude Code, Money Forward achieved remarkable results. The solution saw over 80% engineer adoption and saved an average of seven hours per engineer per week. Specific measurable impacts included reducing API endpoint implementation time by 70% and compressing new developer onboarding from a week to a single day. Claude provided the foundational tool that enabled these significant productivity gains across the engineering organization.
