Also, Michael some of the players in this broad space will deliver anything from any restaurant, so the idea that the food being delivered doesn't compare to what restaurants offer doesn't apply to everyone.
As Hoofar alluded to we need to focus on one model before we can effectively discuss what we think the key differentiator is in that space.
Sadie - What is your focus?
Personally, I'm most interested in companies like Doordash, Postmates, etc. who are focused on delivering anything. UberEATS is interesting in that they partner w/restaurants and offer a limited number of on-demand options.
I think the key for consumers will be customer service, which encapsulates quite a bit but making it easy to order, delivering the food in good shape (temp, not smashed, etc.), communicating via the app or directly w/driver and having a generally positive experience is critical.
If I can order the same pizza from Joe's Pizza Shack from Doordash or Postmates whoever delivers faster and makes the experience more fun and/or easy probably wins.
The other half is the relationships with the restaurants and making sure they are willing and happy partners. That appears to be a challenge Doordash and Postmates are still trying to figure out as if they are truly going to delivery anything it is impossible to establish relationships w/every restaurant up front, but how do you react when an angry, confused restaurant calls you up and asks why you're using their logo, an old menu and sending in people to pick up food for other people and nobody is tipping their waitstaff?
