Satoshi Usami Takes Charge of Supporterz Holdings

In a significant leadership move, Satoshi Usami, the former President and CEO of CARTA Holdings, has reached an agreement to acquire all shares of Supporterz, a prominent HR tech company focused on career support for new engineers. This transition will take effect on April 10, 2026, through the newly established Supporterz Holdings, headquartered in Shibuya, Tokyo.

Supporterz has carved a niche for itself in the HR tech realm by providing high-value matching services tailored specifically for new graduates and engineers. Since its inception, the company has strived to fulfill the vision of "Increasing Cool Adults," building an overwhelming community brand that resonates strongly among engineering students. With a solid foundation to support the burgeoning market of young IT talent, Supporterz is poised for continued growth in today’s digital economy.

With this acquisition, Supporterz will operate independently from CARTA Holdings, allowing for more agile and bold business strategies. Usami, leveraging his extensive experience in business development, is fully committed to facilitating this independence and will work vigorously to enhance the long-term growth of Supporterz.

Usami's Background

Hailing from Aichi Prefecture and born in 1972, Satoshi Usami graduated from Waseda University’s Faculty of Commerce. He began his career at Tohmatsu Consulting (now Deloitte Tohmatsu LLC) and co-founded AccuV.com (now part of VOYAGE GROUP) in 1999 with friends. Under his guidance, AccuV.com successfully went public on the Tokyo Stock Exchange in 2014, transitioning to a First Section listing in 2015. Following a merger with CCI, a subsidiary of Dentsu, in 2019, Usami ascended to the role of chairman at CARTA Holdings. He stepped down from this position in December 2025 after a tender offer from NTT Docomo.

Usami reflects on his journey, stating, "Throughout my tenure at VOYAGE GROUP and CARTA HD, I've driven various business developments. Among these, the vision of 'Increasing Cool Adults' remains steadfast. Supporterz has upheld this exceptional culture since its founding, and there’s ample room for growth in utilizing AI and expanding into new business areas within the HR sector. I look forward to working closely with the management team at Supporterz to enhance long-term corporate value."

Hiroaki Kaede's Perspective

The current CEO of Supporterz, Hiroaki Kaede, adds, "Since our establishment in 2012, we've not only developed matching services for new graduates but also introduced growth projects aimed at career development—services unique to Supporterz that facilitate the realization of our vision. Today, one in three aspiring engineers uses our services, and we have recently launched initiatives for working professionals.
