What P95 does
P95 is a Belgium-headquartered, full-service Contract Research Organization (CRO) specializing in clinical trials and epidemiological research for vaccines and infectious diseases. Founded in 2011 by Thomas Verstraeten (former VP of vaccines at GSK), the company operates across five continents with regional hubs in Europe (Belgium, France, Austria, Netherlands), Africa (South Africa, Kenya, Ghana, Morocco), Latin America (Colombia), North America (North Carolina), and Southeast Asia (Thailand). The service portfolio spans four core areas: Phase I-IV clinical trial delivery, epidemiology and real-world evidence (RWE) studies, specialized Africa and LMIC clinical research, and data management/biostatistics/safety/medical writing. Proprietary and partnered platforms include the id.DRIVE platform (used for COVID-19 vaccine effectiveness studies against variants including JN.1) and the DRIVE influenza vaccine effectiveness framework, which underpins the COVIDRIVE public-private consortium.
The business model is professional services B2B, generating revenue through project-based contracts with pharmaceutical and biotech companies, international health organizations (WHO, Gates Foundation, CEPI), and public health agencies. Pricing is project-specific and quote-based with no public disclosure. Customer concentration is spread across major vaccine manufacturers (AstraZeneca, GSK, Janssen, Sanofi-Pasteur, CureVac), international funders, and government research bodies. Distribution is via direct enterprise sales, supplemented by thought leadership through scientific publications, webinars, the Contagious Thinking podcast, and presence at conferences such as the World Vaccine Congress.
Since May 2023, P95 has been backed by healthcare-focused private equity firm Ampersand Capital Partners. Under PE ownership the company has executed a roll-up strategy: acquiring Pallas Health Research (Netherlands, 2021), merging with OnQ Research (South Africa, 2023), acquiring 4Clinics (Belgium/France, 2024) and Assign DMB (Austria, 2024), and merging with Julius Clinical (Netherlands, November 2025). The Julius Clinical merger transformed P95 from a ~300-person vaccine/infectious disease specialist into a 500+ person global full-service CRO spanning vaccines, infectious diseases, neuroscience, and cardio-renal-metabolic diseases. The combined organization is led by CEO Bassem Saleh, with founder Thomas Verstraeten transitioning to Board Member and Senior Advisor.
