DoorDash 

DoorDash is an online delivery demand aggregator. Consumers can use its app to order food on demand for delivery or in-store pickup from participating merchants. DoorDash creates a marketplace that lets merchants build an online presence, market their offerings, and meet demand through delivery. The firm provides similar services to non-restaurant businesses, such as grocery, retail, and pet supplies. DoorDash is also rolling out emerging technologies, such as drone delivery, to continually innovate and deliver the best possible service to both supply-side and demand-side participants in its marketplace. The acquisition of Instacart, announced in October 2026, will deepen DoorDash's presence in grocery and local commerce delivery.
