How a Small Team Built the Fastest-Growing Clinician App Ever | OpenEvidence Co-founder & CTO Zack Ziegler

OpenEvidence functions as an AI-powered co-pilot for physicians, designed to synthesize vast amounts of medical literature to support high-stakes clinical decision-making. By prioritizing a bottom-up approach, the platform grounds its generative responses in peer-reviewed publications, FDA labels, and society guidelines, ensuring transparency and accuracy through verifiable citations. Unlike traditional medical software that targets hospital systems, the company focuses on direct clinician adoption, achieving rapid growth among U.S. practitioners. The business model relies on display advertising during the system's research and retrieval process. While currently restricted to clinicians to avoid increasing their administrative burden, the technology demonstrates significant potential for improving patient outcomes through better-informed care. As an elite applied AI team, the company emphasizes human-in-the-loop systems, keeping doctors in the driver’s seat while providing powerful, agentic tools to enhance productivity and bridge the gap between complex medical knowledge and point-of-care practice.
