What WCG does
WCG (WCG Clinical Services) is a privately-held clinical research solutions provider founded in 1969 as the first independent Institutional Review Board and headquartered in Cary, North Carolina. The company supports over 4,000 active trials across 130+ countries and is the trusted partner for 94% of all FDA-approved therapeutic agents in the last five years. WCG employs 1,700+ staff across 18 countries and serves pharmaceutical companies, biotechnology firms, contract research organizations (CROs), and research sites through a horizontally-segmented portfolio spanning IRB and IBC ethical review, endpoint adjudication and data monitoring committees, site enablement, clinical trial training, participant recruitment and retention, and benchmarking services.
The company's core technology asset is the ClinSphere platform, a unified cloud environment built on four architectural pillars (Interoperability, Collaboration, Agility, and Continuity) that connects sites, sponsors, CROs, and participants under a single login. ClinSphere integrates purpose-built AI/ML modules including eReview Manager for IRB workflows, Total Feasibility for site selection (with proprietary investigator match scores across 80+ countries), Total Enrollment for participant recruitment, Trial IntelX for AI-powered trial design, AIMS for endpoint adjudication, and CTMS solutions. Supporting infrastructure includes InvestigatorSpace (525K+ active users), SafetyVigilance (250+ country distribution), and the Avoca Quality Consortium's library of 1,500+ tools and templates. The WCG Site Network of 470-500+ site locations and 1,000+ investigators, combined with the 200+ member Avoca Quality Consortium, creates a multi-sided network spanning the clinical research ecosystem.
WCG generates revenue through a hybrid model combining subscription-based SaaS licensing of ClinSphere modules, professional services (IRB and IBC review, endpoint adjudication, statistical consulting, training, and recruitment), and consortium or site network membership fees. Pricing is custom-negotiated under a quote-based enterprise sales motion delivered through field representatives, with multi-year contracts typical. The company has executed a sustained acquisition strategy under PE sponsorship (Leonard Green & Partners, Arsenal Capital Partners, Novo Holdings since 2019), including Intrinsic Imaging (2021), The Avoca Group (2021), VeraSci (2021), Array (2024), and The Contract Network (2026), while divesting its eCOA business to Clario in 2025 to refocus on its core ethical review and AI-enabled platform.
