What if the biggest lever for improving U.S. healthcare isn’t clinical, but operational? In this episode, recorded live at New York Tech Week, a16z General Partner David Haber speaks with Trey Holterman (Tennr) and Christophe Rimann (Camber), two founders tackling the core infrastructure problems that slow down healthcare, from broken referral handoffs to denied insurance claims. They discuss building trust in high-stakes workflows, how better incentives (not just better tech) drive adoption, and why the most defensible products aren’t just smart - they work 97%+ of the time. Plus: advice for founders, the cultural edge of New York startups, and what they’d fix first if they ran HHS.
