OpenEvidence, a medical AI startup, has achieved a $12 billion valuation following a $250 million funding round led by Thrive Capital and DST. The company, known as "ChatGPT for doctors," has seen rapid adoption, with its AI tool used by 40% of U.S. doctors and generating over $100 million in annual revenue. Founded in 2022 by Daniel Nadler, OpenEvidence primarily relies on advertising for revenue, targeting small clinics. Despite competition from larger AI firms, Nadler believes OpenEvidence's real-world usage gives it a competitive edge.
