What Willof Partner does

Willof Partner (株式会社ウィルオブ・パートナー), formerly Rifcamu and originally Combinator, is a Tokyo-based HR technology and services company that has operated referral recruitment platforms and RPO offerings for Japanese enterprises since launching Refcome in 2016. Its core products are two cloud platforms — Refcome, an enterprise-grade referral hiring system bundled with dedicated consulting specialists, and Refcome Teams, a startup-focused platform with Memory Palace, Collaboration, Alert, and Culture modules that enable all employees to participate in candidate sourcing. The company also operates Recpro/リクプロ, an on-demand professional HR matching RPO service that assembles recruiting teams aligned to client hiring challenges, covering strategy design, sourcing, interview scheduling, content creation, and PDCA management.

The business model combines subscription-based SaaS revenue from Refcome and Refcome Teams with project-based RPO/professional services revenue, sold primarily through a sales-led, consulting-driven motion targeting mid-to-large Japanese companies across IT, manufacturing, retail, F&B, and staffing industries. Pricing is quote-based and not publicly disclosed. Cumulative customers exceed 850 companies, with notable enterprise logos including SB C&S, Omron, Sansan, CyberAgent, DeNA, and Ebara. The company joined Willof Work Group as a subsidiary in October 2024 and rebranded to Willof Partner in April 2025, gaining distribution leverage through the parent group's HR ecosystem and a newly announced integration with BizReach's HRMOS採用 ATS in May 2026.

Broad incumbents

• Mynavi: Japan's largest traditional recruitment agency and job-media conglomerate (new-grad and mid-career). Comparable as the broad incumbent whose scale in Japanese recruitment establishes the competitive backdrop Willof Partner competes within, especially for enterprise referral programs.
• Recruit Holdings: Japan's largest HR services conglomerate operating Indeed, LinkedIn-adjacent platforms (via minority stake history), and domestic job-board brands. Comparable as the broad incumbent whose scale and product breadth set competitive context for Willof Partner's niche referral offering.

Emerging players

• SmartHR: Japanese HR cloud platform focused on employment-contract and HR-record digitization for SMB and mid-market. Comparable as a Japanese HR-tech SaaS that bundles operational workflows for HR teams, an adjacent wedge from which referral features could be added.
• Talentio: Japan-based ATS and talent management platform serving mid-market and enterprise. Comparable as a workflow-focused recruiting SaaS in the same Japanese market, with overlapping HR-prosumer buyer personas and potential referral-module overlap.
• HRBrain: Japanese HR analytics and talent-management SaaS for HR departments. Comparable as a Japan-based HR-tech platform targeting similar HR decision-makers with subscription SaaS, representing an adjacent wedge into the same buyer.

Others

• Eight (Sansan): Japan's leading business-card network app operated by Sansan, used for relationship-based sourcing and candidate discovery.

Direct peers

• Bizreach (HRMOS): Operates Japan's flagship enterprise ATS (HRMOS採用) and direct-to-candidate matching business. Comparable as the dominant Japanese HR platform where Willof Partner's referral module now integrates; competes for enterprise HR-tech wallet share and sets the bar for integration-grade functionality.
• Wantedly: Japan's leading referral- and story-driven recruitment platform for startups and mid-market companies. Directly comparable in serving Japanese employers seeking to attract candidates through employee-driven referrals and culture-first messaging, overlapping with both Refcome and Refcome Teams.
