The urgent need that the private sector generate positive social and environmental impacts in order to cope with the grand challenges faced by humanity and contribute to sustainable development, has ignited the need to understand the country conditions that could promote such an endeavor, especially for small firms who may have more difficulties and, among them, those that try to generate positive impacts for multiple stakeholders, such as Certified B Corporations (CBCs). To contribute to such understanding, we use fsQCA to identify the combinations of presence/absence of four entrepreneurial framework conditions (EFCs)—financing for entrepreneurs, taxes and bureaucracy, R&D transfer, and commercial and legal infrastructure—that are sufficient for the presence/absence of a high average impact score of small-size CBCs in the country. The analysis reveals that two combinations of the presence/absence of the considered EFCs are sufficient for the presence and another two are sufficient for the absence of that outcome. General patterns, specific combinations and the implications for policymakers, CBCs managers and future research are discussed.
