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.

Preventing Dialysis Access Failure: How Auvi Labs is Building a Wearable Ultrasound Device

Preventing Dialysis Access Failure: How Auvi Labs is Building a Wearable Ultrasound Device | Rishab Veldur & Kevin Volkema In this episode, I sit down with Rishab Veldur (CEO) and Kevin Volkema (COO) from Auvi Labs to discuss how they're tackling a critical problem in dialysis care. 40% of dialysis patients experience fistula or graft failure within their first year—leading to endless hospitalizations and life-threatening situations. Auvi Labs is building "Beacon," a wearable ultrasound patch that patients can use for just 10 minutes a day to detect early signs of access failure. We dive deep into their journey from a university capstone project to launching clinical pilots, the challenges of building a healthcare startup, and their unique approach to networking and building clinical partnerships. Whether you're a healthcare founder, engineer, or just interested in medtech innovation, this episode is packed with actionable insights.
