founder Jeff Bezos and Salesforce CEO Marc Benioff also invested in Zocdoc in 2008, helping the company expand the service into other cities and healthcare providers. In early 2008, the company received an initial round of $3 million in funding from Khosla Ventures.

It began as a service for dentists in Manhattan, and expanded nationwide to include doctors in over 100 specialties. The service was launched during the TechCrunch40 conference (now called TechCrunch Disrupt) in September 2007. Massoumi had experienced a burst eardrum while traveling and struggled to find available appointments of local doctors and that is where the idea for their business started. Cofounders Kharraz and Massoumi met while working as consultants at McKinsey. Zocdoc was founded in New York City in 2007 by Oliver Kharraz, Nick Ganju, and Cyrus Massoumi, who served as the company's first CEO. Established in 2007, the private company had a $1.8 billion valuation by August 2015, the third-highest for a startup in New York at the time.

The service is free for patients, and doctors pay to advertise their appointment slots. The platform also functions as a physician and dentist rating and comparison database. Zocdoc is a New York City-based company offering an online service that allows people to find and book in-person or telemedicine appointments for medical or dental care.
