HealthTech2Care (HT2C) Podcast featuring Dr. David Langer, Founder & Chief Medical Officer of Playback Health and Chair of Neurosurgery at Lennox Hill Hospital
🎙️ In this episode, Dr. Langer shares the full arc of Playback Health—from burning QuickTime videos on CDs for patients in 2008 to building one of the only ambient AI platforms that sends visit summaries directly to patients today. He explains why patient-facing tools are often overlooked by health systems, how ambient AI changes workflows for clinicians, and what the future holds as voice interfaces, agentic AI, and hospital operations converge.
