You often hear about great CEO’s and their successful companies, but not all CEOs were nearly as impressive when they first began their careers. In fact, like most things, it takes a lot of experience, work, coaching, mentoring, and guidance before anyone gets good.

A CEO coach may not be a profession, but, this week we featured five amazing entrepreneurs in Silicon Valley who have helped countless CEOs to figure out the best way to run their companies. We featured former Ask.com CEO and advisor to Netflix, LinkedIn and Expedia (to name a few) Skip Battle, advisor for Y Combinator Harjeet Taggar, founder of The Funded and The Founder Institute Adeo Ressi, Ben Horowitz of Andreessen Horowitz, and founder of Power Presentations Jerry Weissman.
