From Harvard Business Review
It’s widely believed that the most successful entrepreneurs are young. Bill Gates, Steve Jobs, and Mark Zuckerberg were in their early twenties when they launched what would become world-changing companies. Do these famous cases reflect a generalizable pattern? VC and media accounts seem to suggest so. When we analyzed founders who have won TechCrunch awards over the last decade, the average age at the time of founding was just 31. For the people selected by Inc. magazine as the founders of the fastest-growing startups in 2015, the average age at founding was only 29. Consistent with these findings, Paul Graham, a cofounder of Y Combinator, once quipped that “the cutoff in investors’ heads is 32… After 32, they start to be a little skeptical.” But is this view correct?
Our team analyzed the age of all business founders in the U.S. in recent years by leveraging confidential administrative data sets from the U.S. Census Bureau. We found that the average age of entrepreneurs at the time they founded their companies is 42. But the vast majority of these new businesses are likely small businesses with no intentions to grow large (for example, dry cleaners and restaurants). To focus on businesses that are closer in spirit to the prototypical high-tech startup, we used a variety of indicators: whether the firm was granted a patent, received VC investment, or operated in an industry that employs a high fraction of STEM workers. We also focused on the location of the firm, in particular whether it was in an entrepreneurial hub such as Silicon Valley. In general, these finer-grained analyses do not modify the main conclusion: The average age of high-tech founders falls in the early forties.
These averages, however, hide a large amount of variation across industries. In software startups, the average age is 40, and younger founders aren’t uncommon. However, young people are less common in other industries such as oil and gas or biotechnology, where the average age is closer to 47. The preeminent place of young founders in the popular imagination may therefore reflect disproportionate exposure to a handful of consumer-facing IT industries, such as social media, rather than equally consequential pursuits in heavy industry or business-to-business sectors.
