It's a great idea, in theory. But who's the target market? Wealthy professionals have a wife to bring them stuff or have personal assistants (hard to believe in the world of dual income households, but I have friends that do just this). Young, less wealthy professionals just go pick up the items themselves or have friends pick them up for them. College kids aren't going to pay for such a service, they enjoy taking a break from studying to go pick up something. And yes, I know, I'm sure there are stay at home husbands that do errands for their wealthy professional wives, I just don't know of any.

I had an interview with a YC company. They were going to bring me on board with a low salary, lots of equity, and a seven day work week, with what seemed to be 8-10 hours a day. But hey, they have a cool office and free food!

While I realize that the plural of anecdote isn't data, this is pretty much my point exactly. The venture capitalists take a large position for a small amount of money... minimizing the risk and maximizing their potential profit. the founders try to play a similar game with their highly skilled employees. Welcome to capitalism.
