From what I can tell, AirBnB has a brand and a web application. Technically, I can't imagine the latter is more complicated than the average e-commerce site delivered at scale. I am having trouble understanding how big data can create an advantage (maybe to help owners price their rentals?). If a competitor pops up, there's no reason owners can't list on multiple sites without facing any penalties.
AirBnB is not a company I'd invest in for the long term, while I would invest in Uber/Lyft. So, what am I missing?
