Over the past decade, accelerators have demonstrated their pivotal contribution to the economic and entrepreneurial ecosystem growth. In recent years, a large number of businesses and organizations use corporate accelerators to internalize opportunities provided by startups and idea generators outside the organization. Although this phenomenon has received much attention, especially in Iran, there are still many unclear points regarding the structure, processes, and acceleration programs. In this article, we did a systematic review of 49 articles out of 486 articles published in different journals in the last 5 years. Then, through the PRISMA method, the reviewed data was converted into a structured format in Excel software. At the end, we examined the findings of this study by presenting a conceptual framework detailing the antecedents and consequences of corporate accelerators. Also, in this research, we found that the five main success factors of corporate accelerators are the acceleration program, the creation of a large and committed external communication network, mentoring, the determination of accurate evaluation criteria and the competitive process in selecting startups.
