Accelerator Programs are a growing player in the entrepreneurial landscape that intend to reduce startups’ failure rates and foster entrepreneurial ecosystems. They are important in speeding up the learning process of startup teams at a lower cost (S. L. Cohen & Bingham, 2013; Leatherbee, 2014). One of their objectives is to increase the chances of receiving subsequent funding through angels and VCs (Gonzalez-Uribe & Leatherbee, 2015; Radojevich-Kelley & Hoffman, 2012, S. G. Cohen, 2014; Winston-Smith, Gasiorowski, & Hanningan, n.d.). A critical function of the accelerator is to enhance the social capital of founder teams (S. G. Cohen, 2014; Leatherbee, 2014; Radojevich- Kelley & Hoffman, 2012). Given that social capital is key to the entrepreneurial phenomenon, it is important to analyze its impact on Accelerator Programs participation, and on their relative efficacy on enhancing subsequent startups’ performance.
