"While management styles and practices have been found to be important determinants of firm performance, there is far less evidence on the extent to which management matters for entrepreneurial ventures and whether founders can learn to be more effective managers. Using a randomized field experiment with 100 high-growth technology firms, we show that founders who received advice from other founders with more "hands-on" management styles were more likely to reorient their own management activity, and subsequently experience lower employee attrition and higher rates of firm survival eight months after the intervention. For founders who already had a more hands-on management style themselves, these interactions also increased their rate of hiring. Our study demonstrates management skill can be learned by young firms via networks and subsequently influence performance."
