This is the latest from the 'Technology-enabled Blitzscaling' classes at Stanford. When Reid Hoffman and Jeff Weiner sit down and talk about how you go about scaling a business then some every interesting things come out of it. 

Jeff Weiner joined LinkedIn when it was an interesting 350 person late-stage start-up and has turned it into a global phenomenon with thousands of people and a market cap of >$30 billion. All this in a little over 7 years. 

A lot of credit goes to him obviously, but credit also must go to Reid Hoffman and the Board who let this new guy come in and assume full leadership responsibility - even when some of the changes he made went against their instincts.
