OpenEvidence has rapidly grown to become the most widely used medical AI among verified U.S. clinicians and the fastest-growing clinical decision support platform in the United States. As of January 2026, the privately held company was valued at $12 billion following a $250 million Series D funding round, bringing its total funding to approximately $700 million. Co-founder and CEO Daniel Nadler was recognized on the TIME100 Health list in 2025. In April 2026, OpenEvidence withdrew its AI medical app from the EU and UK markets, citing regulatory uncertainty. The company has established numerous content licensing partnerships with leading medical organizations and journals, including The New England Journal of Medicine, JAMA Network, National Comprehensive Cancer Network (NCCN), and the American Urological Association (AUA).
