This paper investigates post investment cooperation between new venture teams and venture capitalists a propos the longevity of the relationship. Due to the structure of venture capital funds, the authors of this piece argue that the joint effect of the history of interaction between the parties, and time horizon of the relationship, is an especially important determinant of the cooperation within venture-capitalist/new-venture team relationships. The hypotheses were developed and tested empirically on a sample consisting of 70 venture capital backed companies. Both history of interaction and the time horizon of the relationship are found to significantly affect the new venture team’s confidence in cooperation.
