When Marc and Ben first started Andreessen Horowitz, they described this founder leadership capability as “egomaniacal.” Their theory—notwithstanding the choice of words—was that to make the decision to be a founder (a job fraught with likely failure), an individual needed to be so confident in her abilities to succeed that she would border on being so self-absorbed as to be truly egomaniacal. As you might imagine, the use of that term in our fund-raising deck for our first fund struck a chord with a number of our potential investors, who worried that we would back insufferable founders. We ultimately chose to abandon our word choice, but the principle remains today: you have to be partly delusional to start a company given the prospects of success and the need to keep pushing forward in the wake of the constant stream of doubters.
