Special attention was paid to their business models, the structure of ownership, succession, and the specificities of the development stages that family businesses go through. This paper also explored several innovative business approaches that could support the sustainable growth and development of family businesses, and pointed out the vital role they play in the strengthening of their economic structure and competitive advantages on the market. The paper focused on the concept of connecting family businesses into clusters as a strategy for achieving competitive advantages. The aim of this paper was to analyse in detail the strategy of family business clusters and explore how this kind of organization can boost the productivity and innovation capacities of family businesses. The research will be carried out on the example of family businesses operating through a business model of interconnection, using the method of semi-structured interviews with company owners and managers. The survey showed that linking family businesses into clusters improves their sustainable development and competitive advantages. By connecting in this way, family businesses have an opportunity to harness their full business potential, bolster their business for the future and ensure long-term success. For a family business cluster to achieve these goals, it is important to identify potential associates, define common goals at the beginning, and establish clear operating conditions.
