Kevin O’Connor has built and sold companies that reshaped the internet. He co-founded DoubleClick, the advertising technology giant acquired by Google for $3.1 billion, and later launched Graphiq, acquired by Amazon, which made accessing knowledge dramatically easier. And that’s just part of his story.

In this episode, Kevin shares his journey from leaving a PhD program to launching his first startup, navigating the early days of digital advertising, and spotting trends before they become mainstream. He reveals the frameworks that have guided him: how to identify meaningful problems, distinguish fleeting fads from lasting trends, stay adaptable in shifting markets, and persist through the inevitable challenges of building and scaling companies.

For founders, innovators, and anyone curious about long-term impact, Kevin’s story is proof that success comes not from a single breakthrough, but from reinvention, learning, and relentless execution.
