Plex

What Plex does

Plex (株式会社プレックス) is a Tokyo-headquartered, founder-led private company founded in 2018 that operates a diversified services-and-software portfolio aimed at Japan's "essential industries" — logistics, construction, and manufacturing — alongside adjacent verticals such as energy and business succession/M&A. Its core offerings are: (1) Plex Job (プレックスジョブ), a recruitment and job-media platform for essential workers, described as the industry-largest registered user base in its segment; (2) PRORISE CAREER (プロライズキャリア), a professional-talent placement service for IT engineers, consultants, and licensed professionals; (3) M&A Advisory (M&A支援機構), a wholly success-fee M&A brokerage for SME succession; and (4) Sakumiru (サクミル), a SaaS application for construction-site and work-management that has reached 2,000+ enterprise customers. Underlying technology is a web-based Ruby on Rails/PostgreSQL stack with pgvector for vector search and the informers gem for local ONNX embeddings, supporting in-platform candidate/document matching without external model API dependencies.

The company runs a sales-led, field-sales-heavy go-to-market with direct enterprise sales for staffing and M&A, and a mid-market self-serve plus sales-support motion for Sakumiru. Revenue is generated through three mechanics: success-based transaction fees on placements (Plex Job, PRORISE CAREER), recurring SaaS subscriptions (Sakumiru), and success-based transaction fees on closed M&A deals. As of FY2025 (8th fiscal year), Plex reports 9.6B JPY in revenue, 780 employees, 16 office locations in Japan, and 20+ internal business units, with 7–8 consecutive years of profitable growth as a non-equity (bootstrapped) venture. Distribution is concentrated domestically in Japan; the founder, Shun Kurosaki, previously built and ran web-marketing and new-business functions at SMS Co., Ltd. (TSE Prime) before starting Plex with the stated mission of "building the mechanisms that move Japan."
