Learning is central to entrepreneurship and of immense interest in explaining successful venturing (Corbett, 2007). However, little is known about how the source of knowledge acquisition during venture creation affects desirable venture outcomes. We draw on learning and social network theories as well as the knowledge-based view and examine the learning of technology entrepreneurs operating in university-affiliated incubators. We explore questions regarding how 1) the extent of founders’ knowledge acquisition, 2) founders’ reliance on network learning, and 3) the interactive effect of the two, impact both the innovativeness of the initial product or service and first-year sales.
