Lucas GC is a China-based online human capital management platform that connects HR professionals, recruiters, job seekers, and corporate clients across recruitment, outsourcing, and other services. The company operates two platforms — Columbus and Star Career — and uses what it calls an "agent-centric" model built on private professional social networks, where users (primarily HR professionals and independent talent scouts) source and refer candidates within their personal networks. Blockchain technology tracks and monetizes these referrals, while AI and machine learning power candidate-job matching. Lucas GC operates three segments: outsourcing services, recruitment services, and other services. Outsourcing, now roughly 86% of revenue, is the dominant and only growing segment — Lucas GC acts as a turnkey provider, managing technology-related project delivery end-to-end for corporate clients through a network of freelancers and subcontractors, with milestone-based payments tied to project KPIs. The recruitment segment, which handles both permanent placements and flexible/contract staffing, has declined sharply in recent years. In flexible staffing, Lucas GC acts as the employer of record, collecting the full salary package from the corporate client and remitting pay to the candidate. The company also offers IT lead generation for insurance and healthcare clients, and training programs including its own CCRP certification. Lucas GC earns revenue primarily through service fees charged to corporate clients, with a largely variable cost structure driven by subcontractor costs.
