This longitudinal study provides an investigation of the development of size and composition of entrepreneurs’ networks and explores its influence on outcome of the venture emergence process.

Entrepreneurship research has for many years examined the network dimension in the venture emergence process (Larson and Starr 1993), and the effects of networks on entrepreneurial outcome (Elfring and Hulsink 2003). However, the dynamics of the process have largely been ignored (Hoang and Antoncic 2003). This study expands previous entrepreneurship research, by using a longitudinal design and advancement in venture emergence as a process and outcome measure. It attempts to cover dynamics of the process by examining developments in the size of the activated network and the personal and professional network structure changes, through three phases of venture emergence.
