Zocdoc Tech Stack

Healthcare marketplace connecting patients to doctors with instant booking

Internet Publishing New York, NY 501–1,000 employees Founded 2007 Privately Held

Zocdoc operates a two-sided healthcare marketplace—patients searching for appointments, providers managing capacity and patient flow. The tech stack reveals a data-first organization: Databricks + Delta Lake + Iceberg for the lakehouse layer, Looker for analytics, Amplitude for behavioral instrumentation, and orchestration tools (Celigo, Workato, Boomi, MuleSoft) to sync with fragmented provider EMR systems. Active projects signal heavy investment in AI (voice assistant), data infrastructure modernization, and provider conversion optimization—core friction points that directly impact both sides of the marketplace.
