Maybe this was different per region, but I used GrubHub when it first launched in Chicago and even back then they had "their own drivers" (contractors same as Uber/DoorDash). However, I wouldn't be surprised if their roll out involved capturing businesses that already offered delivery drivers until they had a critical mass of drivers in the region or something.
