Mediahouse Holdings has likewise been certified as a "Platinum Partner," the highest partner tier as an officially certified advertising sales agency for "Indeed."

With Mediahouse Holdings joining the Group, both companies will drive initiatives to embody the collaboration philosophy of "By combining the potential of talent and solutions of both companies, and by jointly taking on the challenge of creating further business value, we will lead a period of transformation in the HR market and the digital marketing market, thereby inspiring Japan."

Specifically, by bringing together the digital marketing expertise and their operational know-how as "Platinum Partners" of "Indeed" that both companies have cultivated, as well as interconnecting our respective client networks, we will broadly address the resolution of challenges in marketing and recruitment activities for an even more diverse range of companies. Simultaneously, by utilizing the data infrastructure uniquely developed by the Group along with our speedy and agile production and operational framework, we will optimize business processes and improve productivity.

Moving forward, through these initiatives, we will aim to further enhance our presence in the HR and digital marketing markets as a unified Group.
