ELI - 549 | Building Medical AI That Says "I Don't Know" | Pranav Reddy (ZenMD)
Ask ChatGPT a medical question and it will almost always agree with you. Pranav Reddy thinks that is exactly what makes general-purpose AI dangerous in a clinic, so he built one that stops and says "I cannot verify this" instead of guessing.Pranav is the Co-Founder and Chief Marketing Officer of ZenMD, an India-focused clinical AI platform he built with his sister Rithika Reddy, the company's Founder and CEO. He spent his career in marketing in the US, from an agency internship to director to running his own shop, drawn the whole time to human behaviour and data. She came from a decade in fintech. The idea arrived on a family trip to India, when a friend who had been told for years in the US that they were lactose intolerant was diagnosed by an Indian doctor, almost instantly, with a worm. Different hemisphere, different symptoms, different training data. ZenMD launched in India in May 2026 with four workflows - ZenScribe for voice-to-clinical documentation, ZenNotes for automated OPD notes, ZenConsult for evidence-based decision support, and ZenScan for medical imaging - and a proprietary hallucination correction layer sitting underneath all of it.A grounded conversation about trust, data privacy, and why the hard part of healthcare AI is not the answer, it is knowing when to refuse to give one.Chapters:00:00 - Introduction00:43 - From marketing to human behaviour01:45 - Leaving the agency to build his own02:07 - The inception of ZenMD with his sister Rithika03:34 - The friend who was not lactose intolerant04:17 - The light bulb: connecting both hemispheres05:00 - Why western-trained AI misses Indian conditions06:34 - Why they built ground-up instead of adapting07:41 - Training the models and validating with doctors09:04 - Multi-layer verification: how the algorithm works09:57 - Why ChatGPT will never tell you that you are wrong10:44 - Selling to doctors when you are not one12:08 - Why a marketer and a fintech builder can do this13:01 - Adoption in a pen-and-paper culture13:38 - Repeat users and earning trust14:22 - Why a doctor's time is the real constraint15:07 - ZenScribe and the burden of OPD notes15:19 - The surprise use case: drug dosage16:04 - The supplement that binds to your morning coffee17:07 - The four workflows explained18:33 - Why they are workflows, not products19:25 - The hallucination problem in healthcare20:17 - How ZenMD refuses to guess21:47 - Live testing at medical colleges22:35 - Healthcare data security in India vs the US24:00 - Building for HIPAA, DPDP and ABDM from day one24:54 - Separating who you are from what you have26:40 - Future plans27:10 - Equalizing medical information globally29:02 - NEET prep and medical students on the platform29:32 - Making ZenMD second nature for clinicians30:26 - Closing thoughts---About ELI Podcast:ELI (Entrepreneur's Live Interviews) brings you inspiring stories from India's startup ecosystem.
