   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.

[…] This was huge shift, suddenly the physical walls of medical library that Sam was just talking about came down. In a state of going into a basement, in a library, and flipping through the dusty cart catalogs, or heavy volumes of index medics, you could sit at the desk, tap a few keywords or mesh words, and instantly pull up millions of articles. It was revolutionary at that time, like within few years, PubMed was filling millions of searches every single day. Doctors finally had the words medical knowledge at their fingertip. But there was a catch. Search is not synthesis. And I can tell you from my end, if I'm seeing a patient, I can just call, read an article and expect that this article is going to teach me or tell me how to treat my patients. […]
