<i>I think the main reason Uber &quot;won&quot; is because starting off with the black cars was a much more effective launch approach. As everyone knows, 2 sided marketplaces are very difficult to build. Uber solved this by stocking one side with a pre-existing, semi-organized group of providers.</i><p>That&#x27;s a very astute observation.<p>Anyone have any ideas of other markets(or potential markets) where such an approach could be translated?
