>"Uber for X" does not mean "on-demand for X" Agree. "Uber for X" should really mean "Supply and Demand clearing house/exchange for x". Uber: the x is persona

>"Uber for X" does not mean "on-demand for X" Agree. "Uber for X" should really mean "Supply and Demand clearing house/exchange for x". Uber: the x is personal transportation. Demand = people that need to be transported, Supply = people that have room to transport people. Uber provides a technology based solution - a clearinghouse that pairs the demand to the supply for a fee. AirBnB: the x is short to mid term rooming/housing. Demand = people that need housing, Supply = people that have extra rooms / houses. AirBnB provides a technology based solution - a clearinghouse that pairs the demand to the supply for a fee. If you find a market that has excess supply and excess demand, but no modern software / technology based clearinghouse that VC hasn't tried, you should go for it - chances are you'll be able to corner the market and become very successful. (Just how much will depend on the size of the market...)
