"This report addresses the question: 'How do support programmes fulfil different roles for startups within startup ecosystems?' To put it another way, terms used for programmes supporting startups include: accelerators, coworking spaces, incubators, active seed investors, courses, competitions. But what is the difference?
In trying to answer this, this study interviewed over 30 practitioners, and undertook site visits to startup programmes operating in cities in high-income countries in Europe (Berlin, London, Munich, Cambridge), with the addition of Israel as a close neighbour."

"Humanitarian aid is insufficient to support the unprecedented numbers of fellow human beings who are struggling as refugees, migrants, or modern-day slaves. In this Social Entrepreneurship at the Margins report, Miller Center illustrates the clear and urgent need for bottom-up, enterprise level approaches, and highlights organizations that are already addressing the needs of these groups in innovative ways. This report highlights the efforts of Refugee Investment Network (RIN) and other innovators to bridge these gaps and invites other stakeholders to collaboratively build sustainable solutions for the growing global challenges facing refugees, migrants, and human trafficking survivors."

"This article addresses the specific role of programs that attempt to help social ventures scale. We utilize combined experience in the Momentum Project from ESADE Business School and the Global Social Benefit Incubator at Santa Clara University, as well as an exploratory study of 40 social incubator and accelerator programs around the world, to frame the issues. We make a comparison among different programs and classify them as social incubators and social accelerators according to targeted social ventures and portfolio of resources offered. We note opportunities for research on social entrepreneurship and discuss relevant issues for both academics and practitioners such as the structure of these programs, the variance of approaches, and the resources needed by social ventures in their scaling processes."

"We study the information-gathering role of a startup accelerator and consider the accelerator's incentives to choose a portfolio size and disclose information about participating ventures. We show that in a rational-expectations equilibrium, the resultant portfolio size is smaller than the first-best (efficient) level, consistent with some real-world observations. We further show that when some signals are uninformative and the portfolio consists of mostly high-quality ventures, the accelerator may choose to disclose only positive signals (and conceal negative signals) about its portfolio firms - a strategy we refer to as partial disclosure. Moreover, coupled with pursuing this strategy of partial disclosure, we demonstrate that the accelerator may possess incentives to exit its portfolio firms early."

"This dissertation explores the learning of social entrepreneurs in accelerators. Building on Jarvis' (2010) existential theory of learning, it conceptualises entrepreneurial learning as a process in which purposeful individuals encounter and transform experiences of disjuncture. These experiences are embedded in both human and material contexts. Learning processes and outcomes are portrayed as phenomena that are influenced by social entrepreneurs' interaction with these environments. Accelerators are depicted as non-formal contexts of learning, of relatively short duration - in which the structure and content of education is progressively adapted to the requirements of the individual."

"While business accelerators remain understudied in the academic literature, there is growing interest in understanding how accelerators work and where they provide value to entrepreneurs. In this paper, we focus exactly on this question – we examine how mentorship and investor ties, two key aspects observed across accelerators in general lead to positive accelerator outcomes and through them, to longterm firm success outcomes for the start-ups participating in accelerators. Using the full cohort (n=105) of an international accelerator, we follow the progress of the startups during the accelerated period and continue to follow these startups for 15 months. We find that startups that participate more in mentorship events have higher likelihood of achieving short-term outcomes during the accelerator, such as the release of a prototype and generating revenue for the first time. Similarly, startups that develop more investor ties during the accelerator survive and raise capital at a higher rate. Finally, we find evidence that certain short-term accelerator outcomes also increase the chances of survival and investment. On the basis of these results, we provide practical implications for start-ups as well as managers of accelerator programs, in addition to theoretical contributions to entrepreneurship research."

"This book summarizes five years of learning from data collected as part of the Global Accelerator Learning Initiative. The authors present data describing impact-oriented ventures and accelerators that operate in both high-income countries and in emerging markets. Blending survey data with insights from sector experts, their various analyses shed light on the basic structure of accelerators, showing where they are having their most promising results.

Unlike previous studies, this book does not focus on a few high-profile accelerators (like TechStars and Y Combinator) and startups (like AirBnB and Uber). Instead, it compares a range of accelerator programs that target specific impact areas, challenging regions, and marginalized entrepreneurs. Therefore, it serves as a valuable tool for scholars, policymakers, and practitioners interested in the effectiveness of accelerator programs as tools that unleash the economic potential currently trapped in entrepreneurial dead spaces."

"Organizational sponsorship mediates the relationship between new organizations and their environments by creating a resource-munificent context intended to increase survival rates among those new organizations. Existing theories are prone to treat such resource munificence as the inverse of resource dependence, indicating that the application of new resources in an entrepreneurial context should always benefit new firms. These existing theories, however, often overlook heterogeneity in both types of applied resources as well as founding environmental conditions. By attending to these nuances, we reveal that resource munificence is not necessarily predictive of organizational survival. We find that resource munificence related to sponsorship can potentially decrease or increase survival rates among new organizations and that these effects are contingent on fit of resource type with its respective geographic-based founding density. These findings confirm the need for a more-nuanced theory of sponsorship that attends to the mechanisms and conditions by which resource munificence is likely to alter new organization survival rates."

"Anecdotal evidence of successfully accelerated ventures has been followed by more rigorous studies by GALI and some emerging academic research. But as the evidence behind accelerator effectiveness expands, the question remains-at what cost? This methods brief first frames the various ways accelerators can think about value for money of their programs. Then, it explores one practical approach to calculating value for money. Finally, the brief summarizes similar evaluations conducted for other types of entrepreneur support programs. Accelerators and funders can use this guide to understand their options for assessing value for money and to consider how they could incorporate this concept into their data collection and program assessments."

"Key research objectives of this report were to evaluate the quantifiable value created by impact-focused incubator/accelerator programs and to design and pilot a framework that can be used to objectively compare and benchmark impact incubator/accelerator programs against each other. This analysis builds on ANDE's previous findings and was conceived as a means to evaluate how and where incubators/accelerators are creating tangible value. One of the initial goals of the study was to help programs develop quantifiable evidence they need to make a stronger case for charging incubees and investors for their services and the value they create."
