Services like DoorDash and Postmates Flinstoned by showing a large selection of restaurants, regardless of whether those restaurants had actually signed up. When customers ordered, the apps would send couriers to pick up the food, unbeknownst to the small, local businesses! They would just act as customers, grab the food, and deliver to the users who ordered it. Later on, once the demand had been proven the food apps would form direct relationships with restaurants.
