Edoa Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director: Hiroshi Nakamura) is pleased to announce that it has become a group company of Sansan, Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director & CEO: Chikahiro Terada; hereinafter "Sansan"). In conjunction with joining the group, the company will change its name to Eight Career Inc., effective May 12, 2026.
## Background of Joining the Group
Guided by our mission to "contribute to the progress and development of society through decision-making support," we have addressed corporate challenges through management and organizational consulting, with a primary focus on recruitment. Our strength lies in a support style that accompanies corporate growth from an "organizational" perspective—ranging from defining a company’s ideal vision and designing HR systems and recruitment plans to achieve it, to supporting the recruitment of high-class and executive-level talent, who are highly sought after in the market.
In recent years, acquiring "immediately effective" talent has become an urgent priority for many companies. Against this backdrop, we have joined the Sansan Group, which provides the business card app "Eight"—used by over 4 million business professionals—and the professional recruiting platform "Eight Career Design" built upon it. By combining our expertise in "recruitment consulting from a management perspective" with Sansan’s "Eight Career Design" platform, we believe we can generate significant synergies.
Through this partnership, we will work with Sansan to create new encounters between companies and business professionals, providing even stronger support for the decision-making of both parties. Our entire team is committed to moving forward to create new options in the HR domain that transcend existing frameworks such as job boards, recruitment agencies, and direct recruiting.
