Humanage, Provider of i-web, the #1 Recruiting Management System, Announces Business Partnership with Earth hacks

Humanage Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President & CEO: Ryozo Saito; hereinafter 'Humanage'), a company supporting talent from 'hiring' to 'retention' and beyond to 'success,' announced the start of a business partnership with Earth hacks Inc. (Headquarters: Shibuya-ku, Tokyo; President & CEO: Sumito Sekine; hereinafter 'Earth hacks').

Creating new connections between Gen Z and companies centered on decarbonization.

The recruiting management system 'i-web' serves as the platform enabling student-company encounters.

In the new graduate recruitment market, the job-to-applicant ratio for university graduates has reached 1.62*1, indicating that companies continue to face a challenging hiring environment. Amid this, Gen Z students conducting job searches are increasingly prioritizing values alignment, social impact, transparency, and trustworthiness as key criteria in career decisions.

Earth hacks, jointly established by Hakuhodo Inc. and Mitsui & Co., Ltd., offers diverse environmental solutions focused on decarbonization, such as the 'DecaBoscore,' which quantifies CO2 reduction rates of products and actions. The company also promotes human resources and career initiatives, including 'DecaBo Challenge'—a 5-day joint internship program where Gen Z students co-create solutions to real societal challenges with companies and local governments—and 'DecaBo,' a content platform helping students discover corporate sustainability efforts and reflect on their own careers.

Humanage deeply resonates with Earth hacks' mission to 'effortlessly and enjoyably expand decarbonization choices' and its initiatives offering young generations new career pathways. As part of this partnership, Humanage will provide its recruiting management system 'i-web,' which boasts over 2,800 corporate implementations and holds the #1 market share in the industry*2, as the foundational platform for applicant management across various projects. This enables centralized management of student data and communication from application through selection, supporting the expansion and operational efficiency of Earth hacks' career programs.

Moving forward, Humanage will continue to contribute to corporate hiring success through its 'i-web' recruiting management system and various solutions addressing recruitment challenges.
