IIRC PayPal was very similar - it was sold for $1.5B, but Max Levchin's share was only about $30M, and Elon Musk's was only about $100M. By comparison, many early Web 2.0 darlings (Del.icio.us, Blogger, Flickr) sold for only $20-40M, but their founders had only taken small seed rounds, and so the vast majority of the purchase price went to the founders. 75% of a $40M acquisition = 3% of a $1B acquisition.<p>Something for founders to think about when they're taking funding. If you look at the gigantic tech fortunes - Gates, Page/Brin, Omidyar, Bezos, Zuckerburg, Hewlett/Packard - they usually came from having a company that was already profitable or was already well down the hockey-stick user growth curve and had a clear path to monetization by the time they sought investment. Companies that fight tooth & nail for customers and need lots of outside capital to do it usually have much worse financial outcomes.
