"According to our findings, the number of accelerators serving impact enterpriseshas grown rapidly over the last five years (over 70 percent of the accelerators surveyed were founded in 2008 or later). Despite this strong growth, there is only lim-ited research and data-driven analysis of accelerators’ role in the impact invesment ecosystem. This report aims to generate a greater understanding of accelera-tors in that sector and is part of a broader strategy to analyze, evaluate, benchmark,and strengthen accelerators. It is not intended to be a comprehensive evaluation ofimpact accelerators but an initial assessment of the landscape of these organizations."
