"Accelerator programs are an increasingly important part of entrepreneurial ecosystems. While accelerators have core defining features—fixed-term, cohort-based educational and mentorship programs for startups— there is also significant variation amongst them. In this paper, we relate key variation in the antecedents, organizational design and operation of these programs to theories of firm-level entrepreneurial performance. We then document descriptive correlations between these design elements and the performance of the startups that attend these programs. In doing so, we probe the connections between design and performance in ways that integrate previously disparate research on accelerators and expand our understanding of startup intermediaries. Our findings delineate the building blocks as well as an agenda for future researchers to build upon not only our understanding of accelerators, but also our understanding of what new ventures need to survive and flourish."

"A fundamental challenge for new ventures is overcoming liabilities of newness - particularly, lack of relevant knowledge. Accelerators, intense, time-compressed entrepreneurial programs, attempt to alleviate these liabilities by providing ventures with intensive learning. While accelerators have rapidly emerged as prominent players in the entrepreneurial ecosystem, entrepreneurs, policy makers, and other practitioners have continued to raise questions about their efficacy. Mirroring such concerns, extant organizational theories offer competing predictions about whether and for which ventures accelerator participation might be beneficial. Drawing on hybrid empirical methods that triangulate across multiple quantitative and qualitative analyses, we consistently find evidence that many accelerators do indeed aid and accelerate venture development and that their effects are neither due purely to selection or credentialing. Intriguingly, our results also indicate that accelerator participation complements rather than substitutes for many forms of prior founder experience (e.g., having worked for a company that produces a lot of startups). Overall, we contribute by pioneering work on the nature and outcomes of accelerators, offering insight into the fundamental value of intensive indirect learning (vs direct learning) in new ventures and extending understanding of how organizations may speed products and services to market."

"We examine and discuss the seed accelerator phenomenon which has recently received much attention both in the US and across the globe. While accelerators appear to be proliferating quickly, little is known regarding the value of these programs; how to define accelerator programs; the differences between accelerators, incubators, angel investors and co-working environments; and the importance of the various aspects of these programs to the ultimate success of their graduates, the local entrepreneurship ecosystems and the broader U.S. economy."

"What do accelerators do? Broadly speaking, they help ventures define and build their initial products, identify promising customer segments, and secure resources, including capital and employees. More specifically, accelerator programs are programs of limited-duration—lasting about three months—that help cohorts of startups with the new venture process. They usually provide a small amount of seed capital, plus working space. They also offer a plethora of networking opportunities, with both peer ventures and mentors, who might be successful entrepreneurs, program graduates, venture capitalists, angel investors, or even corporate executives. Finally, most programs end with a grand event, a “demo day” where ventures pitch to a large audience of qualified investors."
