WCG
WCG provides clinical trial services (IRB review, site enablement) and AI-powered trial software to pharma, biotech, CROs, research sites and institutions.
WCG sells regulatory and ethical (IRB) review, clinical trial consulting and site-enablement services, plus technology such as the ClinSphere AI platform. ClinSphere includes Trial IntelX, launched in January 2026 for predictive trial design and site feasibility, and Syneos Health was its first customer. In 2026 WCG acquired The Contract Network to add AI for contract and study start-up work. In October 2026 it launched Activation Intelligence. The company is private equity-backed, having been acquired by Leonard Green & Partners in 2019, and has roughly 1,400–1,500 employees (Tracxn and PitchBook).
