Atena Corp. Joins Kubell Group as a Fully Owned Subsidiary

Kubell and Atena Agreement: A New Chapter Begins

In a significant development in the business landscape, Atena Corporation, headquartered in Chiyoda, Tokyo, has officially reached an agreement with Kubell Inc., based in Minato, Tokyo, regarding the acquisition of all issued shares of Atena by Kubell. This strategic move will lead to Atena becoming a wholly owned subsidiary of Kubell. The acquisition is anticipated to be completed on April 30, 2026, after fulfilling the necessary procedural steps. This inclusion is set to bolster Kubell's group, further diversifying its services in the realm of cloud postal solutions.

Atena Corporation, under the leadership of CEO Naoki Shirahige, primarily delivers cloud-based postal services. Despite the transition into Kubell's corporate family, Atena assures that there will be no alterations to the current service provision structure. The company remains committed to upholding the quality of service and ensuring customer satisfaction as it embarks on this new journey.

Kubell, which was formerly known as Chatwork Inc., has boldly positioned itself with a mission to make work more enjoyable and creative. Known for running one of Japan's largest business chat platforms, Chatwork, Kubell also offers various services that enable companies to outsource back-office functions, including accounting and HR services, via its innovative BPaaS platform called 'Takushita.' This evolution from a business chat provider to a comprehensive work transformation platform illustrates Kubell’s commitment to enhancing the work experience for businesses across Japan.

In light of this acquisition, Kubell seeks to innovate and expand its service offerings while ensuring that Atena's cloud postal services seamlessly integrate into its existing ecosystem. Customers can continue to rely on Atena's services without disruption during this transition phase.

For a deeper understanding of this agreement and what it means for the future of both companies, please refer to the press release published by Kubell: "Kubell Acquires Atena Corporation, Operator of Cloud Postal Service 'Atena' as a Group Company."
