University spin-offs have increasingly received attention from academia, governments and policy-makers. However, there are only a limited number of studies within the university spin-off context which fully understand the contribution made by the founding team to fundraising, specifically how they use their social networks and capabilities. Employing resource-based theory and social networks approach, this paper examines whether a founding team exploits its social networks and capabilities to signal the value of a university spinoff. Capabilities are analysed through a set of constructs -technology, strategy, human capital, organizational viability and commercial resource -that have been derived from previous literature. The contribution made by social networks is evaluated using three dimensions -structure, governance and content -which form the construct of relationships within a network. Based on data from 181 university spin-offs in Spain, this paper empirically demonstrates that by exploiting social networks a founding team can improve its capabilities which, in turn, enhance its fundraising ability.
