PandoDaily founder and editor-in-chief Sarah Lacy chats with Ben Horowitz, co-founder of Andreessen-Horowitz, Netscape, and Opsware, to discuss his early years in Silicon Valley, the Loudcloud "IPO from Hell," sexism in Silicon Valley, his partnership with Marc Andreessen, and his list of top five Silicon Valley founders of all time. His discussion of why courage is the most important virtue for founders is one of the best moments in PandoMonthly history.
