Chris Kuenne, entrepreneurship lecturer at Princeton, and John Danner, senior fellow at the Lester Center for Entrepreneurship at UC Berkeley’s Haas School of Business talk about one of the least understood factors that leads to success at scale: the personality of the company founder. Their research describes four distinct types of highly successful entrepreneurial personalities: the Driver, the Explorer, the Crusader, and the Captain. While popular culture currently celebrates big-ego personalities in the mold of Steve Jobs, the interview guests show how different kinds of people succeed at that level. Kuenne and Danner are co-authors of the new book, “Built for Growth: How Builder Personality Shapes Your Business, Your Team, and Your Ability to Win.”
