With a 56% market share, DoorDash is the largest food delivery company in the United States. It also has a 60% market share in the convenience delivery category. As of December 31, 2020, the platform was used by 450,000 merchants, 20,000,000 consumers, and one million deliverers.

In the fall of 2012, Stanford University students Tony Xu, Stanley Tang, Andy Fang and Evan Moore were getting feedback on a mobile app for small business owners when a macaroon store owner told them of her challenges meeting demand for deliveries. In January 2013, they launched PaloAltoDelivery.com in Palo Alto, California. It incorporated as DoorDash in June 2013.

In December 2018, DoorDash overtook Uber Eats to hold the second position in total US food delivery sales, behind GrubHub. By March 2019, it had exceeded GrubHub in total sales, at 27.6% of the on-demand delivery market. By early 2019, DoorDash was the largest food delivery provider in the U.S., as measured by consumer spending. It maintained that market position in 2019.

DoorDash began expanding into international markets in 2015, launching in Toronto, Canada. The company started operating in markets outside North America in 2019, officially launching in Melbourne, Australia, in September and later expanding further into the country. In 2021, the company expanded its service area to Sendai, Japan in June and Stuttgart, Germany in November. In June 2022, the company expanded into the Wellington Region of New Zealand.

The company expanded its service offerings in 2020, adding grocery delivery initially in California and the Midwest in August 2020. DoorDash expanded the service offerings in 2021 to include DoubleDash, which allows for orders from multiple merchants, and alcohol delivery in 20 U.S. states, the District of Columbia, Canada, and Australia.
