Amusingly, they don't even do things other startups don't already cover. At the LAUNCH hackathon everyone had a free $25 from Postmates: http://postmates.com/ http://postmates.com/ Where you can just order delivery from any store, bakeries included. The Postmates implementation is much better too, with an app where you can watch exactly on a map when someone takes you order (happened in seconds when I tried) and their progress as they go to the store and get you your stuff. Then there's even more general purpose apps like Exec. Anyway, this is what you are told to do at Startup Weekend and the like. Perform customer validation and try your idea out any way possible even before you have an app, but the idea is just something we already have in spades in SF, like you said.
