"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."

"Spring Impact's new report, generously supported by the Argidius Foundation, shares recommendations on creating effective mentoring programs for micro, small, and medium sized enterprises (MSMEs). This report is designed to provide immediate support to practitioners, funders and other champions of mentoring by sharing essential good practices to strengthen or build effective programs."

"This report investigates the role of SGBs in economic growth and the key success factors of business networks for SGBs. It also spotlights the impact of two organizations - Enablis Senegal and CEED Moldova - on SGB growth. Finally, the report outlines implications for funders, ecosystem builders, SGB-support organizations and SGBs."

"What is the effect of exposing motivated youth to firm management in practice? To answer this question, we place young professionals for one month in established firms to shadow middle managers. Using random assignment into program participation, we find positive average effects on wage employment, but no average effect on the likelihood of self-employment. Within the treatment group, we match individuals and firms in batches using a deferred-acceptance algorithm. We show how this allows us to identify heterogeneous treatment effects by firm and intern. We find striking heterogeneity in self-employment effects, but almost no heterogeneity in wage employment. Estimates of marginal treatment effects (MTE) are then used to simulate counterfactual mechanism design. We find that some assignment mechanisms substantially outperform random matching in generating employment and income effects. These results demonstrate the importance of treatment heterogeneity for the design of field experiments and the role of matching algorithms in intervention design."

"We organized business associations for the owner-managers of young Chinese firms to study the effect of business networks on firm performance. We randomized 2,820 firms into small groups whose managers held monthly meetings for one year, and into a "no-meetings" control group. We find the following. (i) The meetings increased firm revenue by 8.1%, and also significantly increased profit, factors, inputs, the number of partners, borrowing, and a management score. (ii) These effects persisted one year after the conclusion of the meetings. (iii) Firms randomized to have better peers exhibited higher growth. We exploit additional interventions to document concrete channels. (iv) Managers shared exogenous business-relevant information, particularly when they were not competitors, showing that the meetings facilitated learning from peers. (v) Managers created more business partnerships in the regular than in other one-time meetings, showing that the meetings improved supplier-client matching."

"This document contains recommendations on creating effective micro, small, and medium sized enterprise (MSME) mentoring programs for practitioners and supporters. A key driver for reducing global poverty and unemployment is increasing the growth and sustainability of MSMEs. While technical assistance, financing, and other initiatives can help MSMEs to achieve growth and sustainability, mentoring can also have high returns on investment. This is unsurprising, given mentoring’s historic origins in the areas of knowledge sharing and social networks. Yet there is a lack of consensus on what defines effective mentoring, evidence on good practices, and guidance on implementation. This publication addresses these gaps."

"This study is a randomized controlled trial (RCT) on the effects of mentoring on SMEs in Norway. We aim to get a better understanding of firm development and dynamics in the presence of public interventions. Does mentoring affect firm performance and firm-survival? Does it matter what type of state aid a firm is granted; mentoring versus the financial equivalent of the service?"
