It's definitely not Kozmo.com, although trying to solve the similar problem of same day delivery. They are aware of Kozmo's shortcomings and have designed their system without the main pitfall of Kozmo: holding inventory. I am friends with the founders and in their office they have a Kozmo.com Delivery bag as a reminder... The main difference is that they use brick-and-mortar stores' existing inventory and connect it with their network of "helpers" and add in their customer service.
Why can't they then just offer their network of "helpers" as a service to any brick-and-mortar store for in-town delivery.
Rather than waiting for a consumer to say they want something from store X -- go to store-x and have them whitelabel the personal delivery service right in their website.
So I go to store X, buy product Y and wunwun is the glue that gets it to me.
I don't even need to know who wunwun is... but then when I get my thing from Store X delivered to me, a little card says "Want your own personal delivery service? Call WUNWUN and we will get you what you need, whenever and wherever you need it, all starting at just $10!"
Good documentary, definitely recommend giving it a watch.
