A teenage friend who builds a company may predict your own entrepreneurship decades later, new research finds. Formal ventures matter more than freelance work.
A teenage friend who later builds a company may do more than stay in touch. New research suggests that friendship itself could predict who becomes an entrepreneur decades later.
The study, led by researcher Seok-Woo Kwon and colleagues, tracked two American cohorts born roughly four decades apart. One was a nationally representative group surveyed in the mid-1990s and followed into participants' late 30s. The other was a Wisconsin cohort followed from 1957 through age 65.
Across both groups, people whose teenage friends later built formal, incorporated companies – registered businesses with a legal identity separate from their owners – were more likely to become entrepreneurs themselves. The relationship held for both incorporated and unincorporated self-employment.
Not every entrepreneurial friend counted. Adolescent friends who worked for themselves informally, as solo contractors or freelancers, predicted nothing at all. Not even entry into the same kind of informal work they were doing.
That distinction matters, because formal and informal self-employment are essentially different populations running different kinds of ventures with different ambitions and earnings. Prior research by the same authors found that formal, growth-oriented entrepreneurship tends to produce greater economic returns.
The relationship extended beyond whether someone started a business at all. People whose teenage friends later built incorporated companies earned more from their own ventures in midlife than people whose teenage friends did not, even after accounting for whether they themselves had incorporated their businesses. The difference persisted among people running the same type of business. Two people with similar ventures could have different earnings depending on what their teenage friends had gone on to build.
How can a friendship formed at 16 still matter at 40? Several possible explanations exist.
One is that adolescence establishes a social channel through which entrepreneurial examples can continue to travel. When a former classmate registers a company, hires staff or raises capital, that achievement may reach old friends through a reunion, a mutual acquaintance or a social media post. Research suggests people are more responsive to information from those with whom they have meaningful social connections than to information from strangers.
This could also help explain why informal self-employment did not show the same relationship. Freelance work tends to remain small and relatively invisible, so it may provide little evidence of what entrepreneurship can become.
One finding complicates a straightforward social-influence explanation: friendships that persisted into adulthood and those that faded were similarly predictive. If ongoing influence were the whole explanation, enduring ties should have mattered more, since they are the ones carrying advice, encouragement and opportunities.
There is another possibility. Teenagers do not choose friends at random. Similarity tends to foster social connection, and adolescents who share an appetite for risk, independence or autonomy may be more likely to become friends. The data cannot fully distinguish between these explanations, both point to adolescence as an important period in the development of entrepreneurial pathways.
The findings fit a broader body of research showing that entrepreneurial trajectories can take shape long before adulthood. Children of business owners are far more likely to become business owners themselves. Evidence from adoptees suggests that environment may matter roughly twice as much as genetic inheritance in explaining who becomes an entrepreneur.
The new study adds another social pathway to this picture. The influence is not only parental, it also appears to run through adolescent peers.
That has implications for how policymakers and educators think about entrepreneurship support. Rather than waiting until young people reach adulthood, schools could instead create places where students interested in building things can find one another: through school ventures, maker spaces or small cohorts. The size of those groups may matter too. The association in the study was strongest among teenagers with relatively few close friends, suggesting that a single entrepreneurial peer may be particularly visible when there are fewer competing social influences.
The findings also change how entrepreneurship programmes might be evaluated. The recent federal evaluation of youth entrepreneurship support in Canada counts loans issued and businesses launched. If entrepreneurial pathways begin taking shape in adolescence, they capture only the end of a process that may have been developing for years.
Entrepreneurship policy should pay more attention to the social environments where entrepreneurial ambitions first take shape. For some, that process may have started long before they had a business idea or even thought of themselves as entrepreneurs: around the lunch table, back in high school.
