What Clariness does

Clariness is a privately held clinical trial patient recruitment and enrollment intelligence company founded in 2005 in Hamburg, Germany. The company operates an integrated enrollment ecosystem called the Clariness Hub, which combines three platforms: ClinSight for enrollment feasibility benchmarking and protocol burden scoring, ClinLife for global patient engagement and recruitment across 60+ countries and 35+ languages, and ClinStudio for collaborative development and deployment of study materials. Clariness has supported more than 2,500 studies over 20 years, randomized over 42,000 patients across 400+ indications, and partners with 12,500+ research sites and 300+ patient organizations.

The company serves four primary customer segments: pharmaceutical sponsors (including 22 of 25 leading sponsors), contract research organizations (CROs), research sites, and patients. Revenue is generated through multi-year outcome-based contracts with three commercial components — setup and systems, outreach and media, and performance delivery — with reported forecast cost accuracy of approximately 90% for patient referral, consent, and randomization. Go-to-market combines direct enterprise sales to sponsors and CROs, CRO channel partnerships (more than 50% of studies are rescue engagements), and a patient- and community-led acquisition motion through the 15M+ ClinLife community. Distribution is supported by offices in Princeton, Austin, Hamburg, Berlin, London, Baar, Cape Town, Shanghai, and Belgrade.

Following its January 2026 merger with SubjectWell, Clariness operates as a combined entity under CEO Jim Corrigan, integrating SubjectWell's US patient infrastructure with Clariness' EMEA and APAC enrollment ecosystem. The leadership team includes a President and Chief Commercial Officer, Chief Operating and Compliance Officer, Chief Technology Officer, Chief Financial Officer, and Chief Scientific Officer, supported by an Enrollment Enablement Team of more than 80 specialists covering 35+ languages. Reported customer satisfaction metrics are 9.4/10 (client), 8.8/10 (patient), and 8/10 (site), with documented performance upside such as 245% of randomization target in a COVID-19 study and 166% in an Alzheimer's study.
