Monstarlab Inc.

Hiroki Inagawa founded Monstarlab in 2006 in Tokyo, starting as a digital agency focused on web and mobile product development. The firm has since expanded into an AI & Digital Partners consultancy, with services spanning product development, payment solutions, and process automation. Its stated mission is empowering transformation through AI and digital technologies, operating under the tagline "AI & Digital Partners." Monstarlab invests in building proprietary platforms alongside client work, including Monstar.ch, Monstar Academia, APPSTARS, and RAX Automation Suite. The firm serves enterprises across multiple sectors — financial services, healthcare, and industrial automation — with confirmed product work in payment systems and AI agent development. Geographically, the firm operates in 12 countries across Asia, Europe, and the Middle East, with additional offices in the Americas. Client delivery is structured through regional offices, each led by a Regional Managing Director. The company maintains multiple entities under Monstarlab HD, including the main Monstarlab entity and separate subsidiaries for specific products. Team size and AUM are not publicly disclosed. Hiroki Inagawa remains Group CEO and Representative Director as of 2026. The firm has a sustainability page and a corporate blog tracking industry trends. Monstarlab's structural differentiator is its dual identity as both a custom software builder and a consulting partner — it designs and deploys products, then often supports internalization for client teams. The firm also offers AI agent development and introduction as a distinct service line, positioning itself as an operating partner rather than a pure advisory firm.
