OpenEvidence raises $200 million at $6 billion valuation, NYT reports

Investing.com -- Medical AI startup OpenEvidence announced Monday it has raised $200 million at a $6 billion valuation, according to a NYT Dealbook report on Monday, nearly doubling its value since July.

The Miami-based company, which offers a ChatGPT-like tool for medical professionals, has seen rapid adoption with its platform now supporting approximately 15 million clinical consultations monthly, up from 8.5 million in July.

Founded in 2022 by Daniel Nadler and Zachary Ziegler, OpenEvidence has designed its AI chatbot to help doctors and nurses reach diagnoses more quickly. The system is trained on medical journals from JAMA and the New England Journal of Medicine, which Nadler described as "blue-chip stuff."

The company’s free-to-use model for verified medical professionals, supported by advertising revenue, has enabled it to expand to more than 10,000 medical centers. Nadler indicated this approach has proven more effective for rapid growth than charging individual health systems.

This latest funding round follows a $210 million investment in July at a $3.5 billion valuation. In total, OpenEvidence has now raised approximately half a billion dollars from investors including Sequoia Capital, Kleiner Perkins, Blackstone, Thrive Capital, Coatue Management, BOND and Craft.

Nadler previously founded an AI startup that was acquired by S&P Global for $550 million.
