John Doerr of Kleiner Perkins on missing a $14 Billion Dollar Investment A Kleiner Perkins partner since 1980, Doerr has backed companies like Symantec, Netscape, Sun Microsystems, Intuit, Amazon, Google and Twitter. Doerr has also gone on to become a big supporter, spokesman and evangelist for reform (and innovation) in education, health and greentech (among others). And, as he showed today at Fortune’s Brainstorm Tech Conference in Aspen, the dude is eminently quotable no matter the subject — success or failure.
