Startup accelerators, which began emerging in 2005 with the launch of Y-Combinator, generally share three characteristics: they tend to be limited in duration; work with cohorts of early stage entrepreneurs; and, aim to facilitate connections with potential investors. In July 2015, the Aspen Network of Development Entrepreneurs (ANDE) and Emory University’s Social Enterprise @ Goizueta (SE@G) program announced the launch of the Global Accelerator Learning Initiative (GALI), a $2.3 million effort aimed toward assessing and analyzing the impacts of these accelerators. In collaboration with Village Capital, GALI released its first report last month, focusing on the effectiveness of accelerator programs, best practices in the space, and estimated impacts. Ultimately, the authors find support that the quality of partners and applicants has a positive impact on accelerator performance, while there is limited support that mentor quality or cohort networking played as strong a role.
