Do Older Entrepreneurs have an Advantage to their Younger Counterparts?

Matty-Sways

Pierre Azoulay and a team of researchers from MIT studied the relationship between age and high-growth entrepreneurship.

Mark Zuckerberg. Evan Spiegel. Elon Musk. Larry Page. Sergey Brin. Steve Jobs. All of these individuals achieved success before turning 30. But is it really the case that young people are more likely to succeed in entrepreneurial ventures?

Current research from the American Economic Review casts doubt on the idea that youth is advantageous when it comes to entrepreneurial success, especially in the case of high-growth entrepreneurship. A team of researchers led by Pierre Azoulay of the Massachusetts Institute of Technology studied the relationship between age and high-growth entrepreneurship.

“Our primary finding is that successful entrepreneurs are middle-aged, not young,” state the researchers. “We find no evidence to suggest that founders in their 20’s are especially likely to succeed. Rather, all data points to founders being successful when starting businesses in middle age or beyond, while young founders appear disadvantaged.” To come to this contrary conclusion, Azoulay and his team pieced together data from records for over 2.5 million entrepreneurs who founded businesses in the United States while excluding sole proprietorships since the 1970’s. The data came from sources including the U.S. Census Bureau’s Longitudinal Business Database (LBD), tax forms, and data from the U.S. Census Annual Survey of Entrepreneurs.

Interestingly, across all ventures, they found the average entrepreneurial age to be 42. Next, they observed founders who were active in growth-oriented entrepreneurship such as biotechnology, social media, and high growth tech. The researchers found that for firms operating in the high tech sector, the average founder age was 43.

The researchers then experimented on whether entrepreneurial age was predictive of success. To do this, they separated out the founders of the most successful entrepreneurial ventures and compared their ages against the broader set. Contrary to the few mega-successful young entrepreneurs such as Zuckerberg, Musk, and Cuban that control the headlines for entreprenuership, they found that more successful startups had slightly older founders. This was the case when the authors defined success in various ways, including whether the founders achieved a successful “exit” (that is, by acquisition or IPO) or by measuring employment growth.

The authors conclude, “The 1,700 founders of the fastest-growing new ventures in our universe of U.S. firms had an average age at founding of 45.0 (compared to 43.7 for the top 1% and 42.1 for the top 5%). Regardless of the measure of technology-intensiveness chosen, we see older founders as we move toward upper-tail performance, especially for the top 1 in 100 or top 1 in 1,000 firms, as well as for founders with successful exits. This evidence is at odds with the conventional wisdom that successful founders skew younger.”
