Founders David McDonald and Adam Grant started Jafflechutes not as a joke, but as a new way to serve hungry urbanites in high density urban cores. And although the concept looks quite funny, the idea of an airborne sandwich bar is not that strange. Smartphone-supported payment systems make serving food accessible for all, even for people living on the 7th floor of an apartment building.
Using gravity to do the serving is relatively cheap compared to hiring a staff of waiters. Also from a real estate point-of-view this idea has potential. Retail spaces are often very expensive on street level, and the prices logically drop when you’re higher up in the building.
