Drawing on the family-embeddedness perspective on entrepreneurship and the resource-based-view of the firm, we investigate how the promotion of family-based brand identity influences competitive orientation (customer versus product) and firm performance in family businesses. Applying structural equation modeling to survey data collected from leaders of 218 family businesses, we demonstrate that developing a family-based brand identity positively contributes to firm performance (growth and profitability) indirectly, via a customer-centric orientation. In contrast, attempts to leverage family-based brand identity via a product-centric orientation do not impact firm performance. Our results suggest that family-based brand identity enhances the family business' ability to persuade customers to make purchasing decisions based on the perceived attributes of the seller. As a result, we contribute to the discussions centered on how to optimize the intricate synergy between family and business.
