Last week was Jeff Bezos' last day in the office, as he's stepping down after almost 3 decades running Amazon. That leaves Facebook, now over $1 trillion market cap, as the largest (by far) of companies that is still led by its founder. If you haven't read Bezos' shareholder letters, I recommend them, his final one is here. The company has grown from a $300m market cap at IPO (when he raised $54m) in 1997 to a market cap of $1.7 trillion. The number of employees has grown from 158 mentioned in the first shareholder letter to 1.3m this year.
