But come to think of it, this is more or less exactly how many dotcoms worked back in the day.
I worked in a startup that was supposed to automate restaurant orders with food and other suppliers over the web to create a b2b market.
The software behind the market website was supposed to entirely automated, but it was just startup employees looking at incoming restaurant orders, and manually matching them to suppliers.
Needless to say, this startup folded quickly, because neither the restaurants or suppliers were willing to pay the startup a cut for the "convenience".
