Despite its theoretical and practical importance, the evolution and development of entrepreneurs' networks has attracted a little attention of researchers. The emerging research literature on this topic found that the dynamics of entrepreneurial networks were contingent upon venture lifecycle, industry and region, and resource needs of the firm. In addition and contrast to the previous research, this article examines the effects of the initial network structure, and firm performance of previous years on the changes in entrepreneurs' network structure, relations, and resources over 4 years. The empirical data is composed of the face-to-face interviews with 75 Russian entrepreneurs in 1995, and the follow-up interviews with 56 original respondents in 1999. I found that the greater the initial network size, the less the increase in network size, strong and weak ties, and resources over time. Further, the findings indicate that revenue growth of previous years predicts the changes in networks in the reverse manner. Thus, I found that the greater the average revenue growth, the less the increase in network size, weak ties, and resources over time.
