"This report examines the performance of early-stage ventures applying to accelerator programs using various growth metrics before, during, and after acceleration. Based on a unique sample of 2,599 ventures applying to 212 accelerator programs, we compare the trajectories of those that ultimately did and did not participate in these programs to learn more about changes in revenue and financing over time. We also compare outcomes across programs and synthesize insights from interviews with high-performing entrepreneurs and accelerator program managers to understand how acceleration can drive longer-term venture development."
