A recent study by three professors at Purdue’s Krannert School of Management is part of a growing mountain of evidence of the superior and more lasting performance of companies where the founder still plays a significant role as CEO, chairman, board member, or owner or adviser. Specifically, the study found that S&P 500 companies where the founder is still CEO are more innovative, generate 31% more patents, create patents that are more valuable, and are more likely to make bold investments to renew and adapt the business model — demonstrating a willingness to take risk to invent the future.
