## What is RPO (Recruitment Process Outsourcing)?
RPO (Recruitment Process Outsourcing) is a service where a company entrusts part or all of its recruitment operations to an external specialized firm. In Japanese, it is also called "saiyou daiko" (recruitment agency) or "saiyou outsourcing," and it supports a wide range of employment types, including mid-career, new graduate, and part-time hiring.
The scope of work undertaken by RPO is diverse, and a key feature is the flexibility to choose services according to the company's challenges and objectives, from recruitment strategy planning to job description creation, scout messaging, candidate management, interview coordination, and follow-up with successful candidates. A major difference from simple task delegation is that it improves and manages the entire recruitment process.
Note that "RPO" also has another meaning in the IT/systems field: "Recovery Point Objective." This article focuses on RPO as recruitment outsourcing.
"**Saiyou Boost**," operated by **Stella Talent Partners Inc.**, is a specialized RPO recruitment support service that cross-optimizes major platforms such as Indeed, Kyujin Box, Engage, and Stanby to support "asset-based recruiting" that does not depend on recruitment agencies.
## Background: Why is RPO in demand now?
### The Recruitment Market Accelerated by Labor Shortages and AI Proliferation
In the 2026 recruitment support industry, "collaboration with AI" that goes beyond simple automation is required against the backdrop of a serious labor shortage. In addition, there is progress in improving the CX (Candidate Experience) through highly transparent information disclosure, a shift to skills-based hiring, and the diversification of channels.
Amid these changes, the demand for "strategic RPO" linked to management strategy is rapidly increasing. However, there are many RPO services, and the key to success is choosing based on "whether it fits our company's issues" rather than "which company is better."
### Structural Recruitment Difficulties in the Building Maintenance and Cleaning Industry
The building maintenance and cleaning industry is a typical labor-intensive industry where labor shortages are chronic. The reality is that many companies see high recruitment costs because they fail to attract applicants even after spending money on job boards. It is precisely in such industries that a shift to data-driven recruitment through the introduction of RPO is effective.
