    I get to talk to a lot of early-stage founders, so it's a special opportunity when I chat with a founder nearing an IPO. Andrew Rubin started Illumio over a decade ago, and the company has been a major success story. In the episode, we discuss how he discovered his love of the CEO role, why he thinks the concept of an "IPO window" is ridiculous, how he prioritizes "the voice of the customer", and more. One of his lines really stuck with me: "Most great companies are built over many years. They almost always go through both good and bad markets." Thanks Andrew!
