Interest in entrepreneurship has grown exponentially in the recent decades. While governments have designed a set of enabling policies that are beneficial to startups and firm growth (Gilbert, Audretsch & McDougall, 2004), and universities established mechanisms to spinoff companies (Shane, 2004), dedicated forms of support such as business have emerged (Hackett & Dilts, 2004). Despite today’s ubiquity of entrepreneurship support initiatives, researchers have found little evidence of its benefits. For instance, the impact of business incubators in firm survival is mixed (Amezcua, Grimes, Bradley, & Wiklund, 2013; Schwartz, 2008) which be explained by a multitude of support strategies (Clarysse et al, 2005) not necessarily sharing the same outcome (Bergek & Norrman, 2008).

Against this backdrop, it is legitimate to ask: what do we know about supporting entrepreneurs? After decades of public and private investment poured into entrepreneurship support initiatives, what is the rationale of the many sources and types of support? More importantly, what do we know about the efficacy of each of these initiatives? And how do different sources and types of support fare when compared to one another?
