An interesting counter point, VC&#x27;s as an industry average significantly lower ROI than the boring old S&amp;P 500.  One way to look at the VC industry is to realize VC&#x27;s can make millions even if there portfolios have negative ROI.  What they need is to manage lot&#x27;s of money and being in on the ground floor of the Next Twitter buy&#x27;s lot&#x27;s of credibility.<p>In that context, a company that reaches 50 billion in 30 years is far less valuable to a VC than a company that hit&#x27;s 10 billion in 3 years and then goes bust in 10 years.
