New research shows that size of social network matters for entrepreneurs.
The authors found that firms whose managers have more social relationships with peers at other software start-ups have a better chance of surviving external shocks, such as the burst of the dot-com bubble earlier in the decade. This result suggests that cultivation of strong and relevant social networks among a firm's managers can be an important determinant of the success of a startup venture.
The research is based on a multi-year study of 100 software start-ups in Israel. Original data was collected from start-ups during the dot-com economic growth. Eight years later, the authors examined new information about the ability to survive the bubble's burst.
So I guess those emails that keep getting flagged in my spam filter were actually trying to educate me about entrepreneurship.
