The link between new venture survival and the presence of founding teams is investigated, in particular the effect of the gender composition of teams. Furthermore, we study venture survival, gender, and institutional change. A unique longitudinal database is employed, covering a large number of Swedish ventures established during 6 specific years, 1930-2005. These data capture the initial gender diversity of start-ups. The contextualization of entrepreneurship involves situational and temporal boundaries, and we elaborate on contextual factors at different levels of analysis. Our results show that ventures founded by teams have a higher probability of surviving, but show no overall team gender homogeneity/heterogeneity effect. However, we find some support for the fact that ventures founded by all-female teams have lower survival chances. Nevertheless, the clearest negative effect is found for female solo start-ups. Furthermore, our results support the fact that institutional transformation may gradually have increased the likelihood of ventures founded by females to survive.
