Parachute delivery after mobile payment
David McDonald and Adam Grant wanted to serve sandwiches from the 7th floor of a building, one of the reasons was the lack of affordable retail spaces on street level. They chose to use parachutes and started the Jafflechute company. The customers have to pay via a smartphone and can pick-up their order at a mark near the building.
