Purpose: The article presents business models developed in organizations of the “new cooperativism” trend, whose application leads to a bottom-up solution of important social problems at the local level and, in a broader perspective, stimulation of sustainable development.

Methodology: The adopted methodology uses a qualitative approach. The research was conducted in the form of case studies of four organizations following “new cooperativism,” based on in-depth interviews, observations, and analyses of organizational documents and various types of publicly available materials.

Findings: The study showed that “new cooperativism” organizations use in their business models the old practices developed by classical cooperatives, which work well in today’s conditions and have the potential to provide a positive impact on important socioeconomic dysfunctions, which can be fully implemented through modern technologies.

Research Limitations: The limitations typical of the case study method entail the uncertainty of results replication, which disallows their broad generalization. However, the obtained results indicate the need to conduct a scientific diagnosis of emerging collaborative grassroots organizations and the importance of their participation in the three-sector economic concept of the state.

Originality: The article and its conclusions are based on empirical research of the practical effectiveness of business models used in organizations of the “new cooperativism” trend.
