DoorDash tested its idea with a fake website before building anything.
In 2013, Andy Fang and his co-founders put up a page, paloaltodelivery.com, listing local restaurant menus. There were no drivers, no software, no infrastructure, so when orders came in, the founders drove the food themselves. When DoorDash went public in 2020, three of them became billionaires.
