This paper seeks to understand the role of proximity to Silicon Valley and the Silicon Valley network effect on venture success. Despite the wealth of literature on the role and importance of geographic proximity in the venture capital process, no studies have specifically examined the impact of geographic proximity to Silicon Valley on venture success. I build my study on existing literature but deviate from past research in the following ways: first, I narrow the research question to the relationship between geographic proximity to Silicon Valley and successful exit; second, I consider success from the perspective of the venture rather than the venture-backing firm; third, I employ a logistical model as well as a linear probability model; fourth I control for endogeneity by isolating first rounds; lastly, I exclude syndicated deals, focusing on 1:1 venture-backing firm-to-venture deals. I use VenureXpert data for Silicon Valley-backed firms located both in and outside Silicon Valley to test hypotheses regarding geographic proximity. The results are significant and suggest that venture location in Silicon Valley is associated with greater venture success. Based on the results, it is clear that the impact of the Silicon Valley network effect is statistically meaningful and should encourage ventures to continue to strategically locate themselves in Silicon Valley.
