I know I'm over simplifying this - but if I was wanted to be in this space, I'd partner with grocery stores to build their tech, and charge the groceries incremental fees off each sale without taking on inventory / capital risk.
I'm just not sure about Gobble, blue apron, hello fresh et all... how are they differentiating themselves operationally? (Besides throwing money at having their own refrigerated distribution centers)
FedEx-ing food around seems like a gigantic waste of resources and seems at odds with "changing the world" for better. But that's just me.
*I'm a "busy millennial" with a good tech job who enjoys cooking - so I guess I'm in their target market?
