It is often assumed that family ownership, which consists of individuals who share a common history and values, is homogenous. However, family owners exhibit varied patterns of engagements toward ownership because of differences in their roles, goals, needs and expectations within the family and the business. The research gap lies in the limited understanding of the heterogeneity among family members in relation to ownership. To address this research gap, this article adopts a configurative approach to develop a typology of family owner styles grounded in a psychological perspective and to validate it empirically. The proposed classification model combines two psychological states—agency stewardship intention and harvesting-creation motivation—which identify four distinct family owner styles: Active, Intra-Entrepreneurial, Entrepreneurial, and Detached owners. Additionally, by bridging the gap between academia and practice, this study presents a free access self-assessment online application, enabling family owners to identify their own ownership style.
