INREVO Co., Ltd. (Headquarters: Hakata-ku, Fukuoka City, Fukuoka Prefecture; Representative Director: Haruhito Minami) announced that in February 2026, "Hitotore Saiyo," its RPO (Recruitment Process Outsourcing) service that provides end-to-end support for the entire recruitment process, has surpassed a cumulative total of 250 client companies.
"Hitotore Saiyo" is a recruitment outsourcing service that not only delegates recruitment activities externally but also aims to enable companies to conduct their own recruitment by consistently supporting the sharing of necessary know-how and the establishment of reproducible recruitment processes. To date, it has contributed to stable talent acquisition by optimizing recruitment processes and improving the overall operational quality of recruitment activities across more than 30 industries* and over 30 job categories*.
"Hitotore Saiyo" surpassed 200 client companies in 1 year and 11 months since its launch, and then exceeded 250 companies in just two more months. We believe that this achievement of 250 companies is a result of the reproducibility and effectiveness of our support, tailored to each company's challenges and regional characteristics, being highly evaluated across a wide range of industries and job categories.
*Based on our company's classification and aggregation results.
■ Background to Surpassing 250 Companies | A System Capable of Broad Recruitment Support and Expanding Continuous Use
The background to "Hitotore Saiyo" surpassing 250 client companies lies in its support system capable of covering a wide range of recruitment-related business areas. In traditional recruitment outsourcing, it is common for one person to support multiple companies in parallel, which can limit the scope of support and lead to variations in quality and response speed for different tasks.
In contrast, "Hitotore Saiyo" provides extensive support for recruitment activities, from designing recruitment strategies, selecting job boards, creating job descriptions, sending out scouts, candidate communication, progress management, to proposing improvements. Its distinctive feature is that it does not merely act as a single-task recruitment agent but consistently supports the necessary steps while overseeing the entire recruitment process.
This extensive support is made possible by a division of labor system where roles are separated by function. Teams with expertise in each area collaborate to provide support, thereby maintaining high standards of quality and response speed throughout the recruitment process and achieving results-driven assistance.
Furthermore, for companies using recruitment outsourcing for the first time, we offer a fixed-rate trial course at 100,000 yen per month, catering to the need to "first see the capabilities of Hitotore Saiyo." In addition, we provide a full-commitment course starting from 300,000 yen per month for organizational expansion and planned recruitment, offering options tailored to each company's recruitment phase and challenges.
In addition to its comprehensive support system and easy-to-introduce plan design, "Hitotore Saiyo" maintains a recruitment success rate of over 90%*, and based on this track record, the number of companies continuously using our monthly contract services is increasing. This expansion of continuous use is a testament to the high level of satisfaction with the service, and this accumulation has led to the current result of surpassing 250 client companies in just two months after reaching 200.
*: Recruitment success rate is based on our company's research (based on recruitment results up to February 2025).
Moving forward, through "Hitotore Saiyo," we will continue to strengthen our support tailored to the diverse recruitment challenges of our client companies, aim for further improvements in recruitment success rates, and contribute to their sustainable growth in a market environment where competition for talent acquisition is intensifying.
