Founded in 2013 and headquartered in San Francisco, DoorDash is an online food order demand aggregator. Consumers can use its app to order food on-demand for pickup or delivery from merchants mainly in the US. Through the acquisition of Wolt in 2022, the firm also provides this service in Europe. DoorDash provides a marketplace for the merchants to create a presence online, market their offerings, and meet demand by making the offerings available for pickup or delivery. The firm provides similar service to businesses in addition to restaurants, such as grocery, retail, pet supplies, and flowers.
