Rakumo

Established in December 2004 as Nihon Gigei Inc., Rakumo Inc. is a publicly-traded company on the Growth market of the Tokyo Stock Exchange (4060). The company specializes in providing cloud-based software-as-a-service (SaaS) solutions designed to enhance business productivity. Rakumo's core business revolves around developing and selling its proprietary suite of tools that seamlessly integrate with major platforms like Google Workspace and Salesforce, addressing functionalities that the standard versions of these services might lack. This focus allows them to serve a client base of medium to large enterprises looking to optimize their operational efficiency and internal collaboration.

Rakumo generates revenue through a subscription-based model for its SaaS products. In addition to software licensing, the company's business activities include the resale of Google Cloud products, providing installation and customer support, and offering IT offshore development services through its Vietnamese subsidiary, RAKUMO COMPANY LIMITED. This multi-faceted approach provides diverse income streams and a comprehensive service offering. The company has demonstrated consistent growth, reporting a 13.8% increase in net sales for the first quarter of 2025. As of December 2023, the company reported sales of JPY 1,295 million.

The company's history includes several key milestones. Originally founded in Shibuya, Tokyo, it changed its name to Rakumo Inc. in 2015. A significant step in its expansion was the 2018 acquisition of AOI Systems Vietnam Co., Ltd., which was subsequently renamed RAKUMO COMPANY LIMITED, bolstering its offshore development capabilities. Rakumo Inc. went public with an initial public offering on the Tokyo Stock Exchange Mothers market in September 2020. The leadership team includes Chairman Daisuke Mitarai and President Group CEO Koji Shimizu.

The Rakumo product suite is a key differentiator, offering a range of tools designed to fill the gaps in standard groupware. These include features such as a customizable organizational hierarchy calendar and an advanced internal bulletin board with access control, which are particularly valuable for larger organizations with complex structures. The platform also provides comprehensive attendance management solutions. This focus on practical, user-friendly enhancements has resulted in a high customer retention rate, reported to be over 99%.
