From Human Capital to Social Capital: A Longitudinal Study of Technology–Based Academic Entrepreneurs

This article develops theory relating to how differences in the human capital of academic entrepreneurs influence their ability to develop social capital that can address the barriers to venture development. We examine the development of social capital by three types of academic entrepreneurs with differing levels of entrepreneurship experience: nascent, novice, and habitual entrepreneurs. Using a longitudinal study, critical differences are observed between the structure, content, and governance of their social networks. We propose that entrepreneurs with prior business ownership experience have broader social networks and are more effective in developing network ties. Less experienced entrepreneurs likely encounter structural holes between their scientific research networks and industry networks. Support initiatives help attract industry partners for novice entrepreneurs from engineering and the material sciences but academics based within biological sciences encounter greater difficulties building such ties. Regardless of academic discipline, business ownership experience appears essential to learn to build relationships with experienced managers and potential equity investors.
