That said, I can't help but wonder whether the company will find a business model with sustainable economics. A lot of really smart people have tried and failed to accomplish this sort of thing before. For example, Amazon invested $60 million in Kozmo.com back in the late 90's, and they couldn't make it work. (Kozmo.com ended up raising a quarter billion dollars before shutting down.)[1]
The main challenge is that same-day, point-to-point delivery is very expensive -- a complex problem. (Most delivery systems in use today rely on some kind of hub-and-spoke design.) Perhaps the wide adoption of smart phones will make point-to-point delivery economically viable for Instacart -- e.g., by giving the company cost-effective access to underused delivery vehicles as needed to satisfy the ebbs and flows of consumer demand.
I'm curious to see if and how Instacart can pull it off.
