Its core products include rakumo for Google Workspace, a cloud-based platform enabling calendar and address book sharing, electronic approval systems, electronic bulletin boards, expense settlement systems, and time attendance management. The company also provides rakumo for Salesforce, which synchronizes and links Salesforce calendars while connecting client and sales data.

In recent major developments, rakumo completed the acquisition of Agent Share Corporation in July 2025 to strengthen its human resources domain. It also acquired Startre Co., Ltd., a web service provider, as a subsidiary in mid-2025, expanding its service offerings. Furthermore, the company initiated co-development of a new product, rakumo Board, designed for Microsoft 365 integration, promoting extended cooperation with major cloud platforms. These strategic moves align with its mid-term management plan focused on high growth in SaaS and broadening its cloud business ecosystem.
rakumo operates within the IT services and cloud software industry, targeting corporate customers seeking to enhance operational efficiency through cloud collaboration tools and integrated business platforms. Its geographic operations are primarily centered in Japan, offering products that seamlessly integrate with global platforms such as Google Workspace, Salesforce, and Microsoft 365.
