Successful Founders Average 45, Study Finds
New research indicates that the average age of founders of the fastest-growing new companies in the U.S. is 45, challenging the common narrative of young entrepreneurs.

Contrary to the popular image of young founders, new research suggests that age and experience are significant assets in entrepreneurship.
A study by MIT Sloan professor Pierre Azoulay and his colleagues analyzed the fastest-growing 0.1 percent of new American companies based on employment growth over their first five years. The findings reveal that the average founder is 45 years old.
This average holds true across the economy, with the average U.S. founder being 42. Even in the software industry, often associated with youthful founders, the average age at incorporation is 40.
The researchers attribute this age advantage to accumulated human capital, social capital, and financial capital. The study also suggests that industry mastery, which takes years to develop, is crucial for identifying market opportunities.
The research provides a data-driven perspective, highlighting that maturity and experience can be key factors in building successful, high-growth companies.
