OpenEvidence

AI medical information platform that answers clinical questions with citation-backed summaries of published evidence.

OpenEvidence, founded in 2022 and headquartered in Miami, Florida, provides an AI platform that answers clinical questions with summaries grounded in and cited to published medical literature, used by clinicians at the point of care and free for verified U.S. clinicians. OpenEvidence documents HIPAA compliance and SOC 2 Type II certification. For pharma and biotech teams its relevance is primarily in medical affairs and evidence engagement; it is not a validated GxP system. OpenEvidence raised a $250 million Series D in January 2026, bringing total funding to roughly $700 million.
