"Recent years have seen the emergence of a new institutional form in the entrepreneurial ecosystem: the seed accelerator. These fixed-term, cohort-based “boot camps” for start-ups offer educational and mentorship programs for start-up founders, exposing them to a wide variety of mentors, including former entrepreneurs, venture capitalists (VCs), angel investors, and corporate executives, and culminate in a public pitch event, or “demo day,” during which the graduating cohort of start-up companies pitch their businesses to a large group of potential investors. In practice, accelerator programs are a combination of previously distinct services or functions that were each individually costly for an entrepreneur to find and obtain. The accelerator approach has been widely adopted by private groups, public and government efforts, and by corporations. While proliferation of accelerators is clearly evident, with worldwide estimates of 3000+ programs in existence, research on the role and efficacy of these programs has been limited. In this article, I provide an introduction to the accelerator model and summarize recent evidence on its effects on the regional entrepreneurial environment."

"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."

"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."

"Recent years have seen the rapid emergence of a new type of program aimed at seeding startup companies. These programs, often referred to as accelerators, differ from previously known seed-stage institutions such as incubators and angel groups. While proliferation of such accelerators is evident, evidence on efficacy and role of these programs is scant. Nonetheless, local governments and founders of such programs often cite the motivation for their establishment and funding as the desire to transform their local economies through the establishment of a startup technology cluster in their region. In this paper, we attempt to assess the impact that such programs can have on the entrepreneurial ecosystem of the regions in which they are established, by exploring the effects of accelerators on the availability and provision of seed and early stage venture capital funding in the local region."
