How to Build a 50 Billion Dollar Startup?

What i started noticing is that the compani's most likely to be worth a billion or two, regardless of found or quality, were those who had market poll. What you needed in order to go from,. let's say, a billion to 50 billion was a killer team, or a team that became killer overtime. So when i'm investing in a founding team, i'm not looking for a team that's necessarily capable of building a 50 billion dollar company to day. I'm looking for a growth just like youre betting on a start up with the growth curve - where is the founder's ability to keep learning?
