Zocdoc
Zocdoc is a New York-based healthcare marketplace that lets patients find in-network doctors and dentists, read verified reviews, and book in-person or telehealth appointments in real time - free for patients, paid for by providers who advertise their open slots. Founded in 2007 after a co-founder's burst eardrum exposed how hard it is to get a timely appointment, Zocdoc now serves millions of patients monthly across all 50 states, hundreds of specialties, and thousands of insurance plans, and in 2025 added Zo, an AI voice agent that answers scheduling calls 24/7.
