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 “account aggregation” technology to gather user data, turning it into useful insights for our customers.\nAs announced in \"Money Forward AI Vision 2026(https://www.linkedin.com/pulse/full-transcript-money-forward-announced-ai-strategy-vision-phwoc/?trackingId=sl33ZIGRFzkBJJv7wI9qsg%3D%3D),\" we view AI utilization not as an option, but as a prerequisite for sustainable enterprise growth. Guided by executive leadership, we are accelerating an all-in AI shift across the entire company.\nRather than treating AI merely as an efficiency tool for existing tasks, we fundamentally ask, \"How should this process exist in the first place?\" to reconstruct products and workflows optimized for the AI era. Powered by a rich, active user base and vast datasets, we strictly practice AI-driven development engineered backward from maximum user value. Internally, we actively integrate generative AI tools into our development environments, driving radical productivity gains and rapid product iterations.\nWe are looking for motivated engineers who want to embrace new technologies without fear of failure in this period of global trial and error-and who are truly passionate about building high-impact AI services grounded in massive real-world data.\nOverview\nAt Money Forward, we are driving company-wide business transformation through Generative AI (AX).
