Zocdoc is the healthcare access infrastructure that connects patients to great care. By powering seamless scheduling wherever patients are seeking care, Zocdoc helps them move from being stuck to being seen. Each month, millions of patients find and book appointments with providers, powered by Zocdoc—on the company’s website and app, and across online search, insurance directories, providers’ websites, practice phone lines, AI platforms, and more—with the typical appointment happening within 24 to 72 hours from booking. With nearly two decades of experience unifying healthcare’s fragmentation, Zocdoc is uniquely positioned to power access across insurance plans, EHRs and PMS systems, specialties, visit types, and provider organizations of every size. By fixing healthcare at the start, Zocdoc empowers patients to get the care they need, when they need it, while delivering scaled patient growth providers can count on.
