I see Uber, Lyft, Amazon Fresh, Instacart, etc and I can't understand why they take the market by storm like that. They are not the first to ever think about that, their service isn't super great (except for Amazon, I'd say) and still, in the US, it seems like the market just sits and waits for them. Then a majority of people jumps in and the thing skyrockets.
Meanwhile, in other countries, small to medium-sized companies have had online groceries ordering for many years, local taxi unions have had websites and recently apps, and still... it's like OMG so much innovation from US companies let's give them crazy valuations.
What gives? Is it market size?
