Miami-based AI startup OpenEvidence has secured a $250 million funding round at a $15 billion valuation, led by Andreessen Horowitz and hospital systems. The company, which provides AI-driven clinical search for physicians, is expanding into drug development and global healthcare access.
NBC News reports that OpenEvidence, a free AI-powered medical search tool, is now used by about 65% of U.S. doctors and roughly 1.2 million clinicians worldwide, handling tens of millions of queries to aid clinical decisions, exam prep, and note-taking. It aims to supplement clinicians’ judgment with rapid, licensed evidence from top journals and organizations. While widely praised for speed and access to high-quality sources, experts warn of potential hallucinations, gaps in patient-outcome research, privacy concerns, and the risk of overreliance among trainees. Hospitals vary in privacy practices and some are integrating it with electronic health records, as competition with UpToDate and other AI tools grows; OpenEvidence is ad-supported, free for users, and undergoing ongoing studies to assess its impact on care.
OpenEvidence, a rapidly growing medical AI platform used by over 40% of U.S. physicians, announced a $210 million Series B funding round at a $3.5 billion valuation, and launched OpenEvidence DeepConsult™, an AI agent designed to assist physicians with advanced medical research, aiming to improve clinical decision-making and patient outcomes.
Daniel Nadler, a Harvard Ph.D. and former billionaire founder, built OpenEvidence, an AI-powered platform that helps doctors quickly access and analyze the vast and growing body of medical research, raising $210 million at a $3.5 billion valuation, and signing up over 430,000 U.S. doctors, with the potential to revolutionize healthcare information access.
Artificial intelligence is transforming how doctors access medical knowledge by providing faster, more focused search capabilities. Traditional methods like PubMed and UpToDate are being enhanced with AI-powered tools such as OpenEvidence and Consensus, which offer direct answers to medical queries by synthesizing information from peer-reviewed sources. While these AI tools improve efficiency, they also raise concerns about automation bias and the need for clinicians to critically evaluate AI-generated information. The integration of AI in medical practice aims to balance speed and accuracy, ultimately enhancing patient care.
OpenEvidence, a health AI startup founded by Daniel Nadler, aims to address the knowledge cutoff problem faced by large language models in the medical field. By marrying language models with real-time clinical documents, OpenEvidence's AI chatbot can provide up-to-date information from the latest research and scientific studies. The startup, valued at $425 million, is competing with the incumbent database UpToDate and aims to offer interactive and tailored answers to healthcare professionals, saving them time and improving patient care. OpenEvidence has raised $32 million in funding and is currently free for licensed medical professionals to use.
