Scores of top-tier entrepreneurs worked for established corporations before they struck out on their own and became self-made billionaires. People like Mark Cuban, John Paul DeJoria, Sara Blakely, and T. Boone Pickens all built businesses—in some cases, multiple businesses—that are among today’s most iconic brands. This fact raises two profound questions: Why couldn’t their former employers hang on to to these extraordinarily talented people? And why are most big companies unable to create as much new value as the world’s roughly 800 self-made billionaires?
John Sviokla and Mitch Cohen decided to look more closely at self-made billionaires because creating $1 billion or more in value is an incredible feat. Drawing on extensive research and interviews, the authors concluded that many of the myths perpetuated about billionaires are simply not true. These billionaires aren’t necessarily smarter, harder working, or luckier than their peers. They aren’t all prodigies, crossing the billionaire finish line in their twenties. Nor, most of the time, do they create something brand-new: More than 80 percent of the billionaires in the research sample earned their billions in highly competitive industries.
