How OpenEvidence Became a $12 Billion AI Healthcare Giant | Full Breakdown
OpenEvidence just hit a $12 billion valuation — here's the full story of how it happened. Daniel Nadler sold his first company, Kensho, to S&P Global for $550 million. Then he turned his attention to one of the most broken systems in the world — medical information. Hosts Roupen Odabashian, MD and Osama Hyder break down the full story of OpenEvidence — the AI-powered clinical decision support platform now used by 40% of US physicians, handling 358,000 queries per day. We cover Daniel's origin story from Toronto to Harvard PhD, the Federal Reserve, and the founding of Kensho in 2013. We explore the $550M S&P acquisition, his parallel career as a published poet and MoMA PS1 board member, co-founder Zachary Ziegler's background, the Mayo Clinic partnership, domain-specific AI architecture, the USMLE 100% score debate, and the explosive growth that followed. The second half dives into the funding roadmap (Series A–D), product expansion into AI Scribe and DeepConsult, the direct-to-physician business model, monetization strategy, competitive analysis, network effects, and bear case risks. Whether you're a physician, a health tech founder, or an AI investor — this is the most in-depth breakdown of OpenEvidence you'll find anywhere.
