Listen up if you run a Fortune 500 company or a startup. Steve Case says the world is moving into a “third wave,” and you’ll need a new playbook if you want to be successful.

He knows a lot about leadership. After all, he’s the tech-savvy entrepreneur who founded AOL (America Online) and made the Internet part of everyday life, long before Google ”GOOG” or Facebook ”FB” came along. He’s out with a new book, The Third Wave: An Entrepreneur’s Vision of the Future, which lays out his view of what the next chapter of the Internet means for business leaders.

Case tells Fortune’s Susie Gharib that the smart companies will be the ones that recognize that if they don’t innovate, take risks, or experiment, they will lose their way. “The biggest risk is doing nothing,” he says.

His biggest tip for future leaders? Partnerships are important. Case encourages leaders to follow the wisdom of an African proverb: “If you want to go quickly, go alone. If you want to go far, go together.”
