Long-established family firms are endowed with a bundle of beliefs and practices that constitute their tradition. However, to remain competitive, they need to renew their products and production processes. Such forces pulling toward the past and the future, antithetically calling for continuity and change, seem paradoxical. In an abductive analysis of eight long-established family firms in Turkey, we identify four equifinal strategies to manage this paradox. Adopting a family imprinting perspective, we theorize how the long-lasting legacy of previous family generations shapes different approaches to innovation and tradition depending on the content imprinted on the current family generation. Contributing to family business, imprinting and innovation research, we identify the new construct of temporal symbiosis as a firm’s simultaneous adoption of retrospective and prospective approaches to using its resources to concurrently perpetuate tradition and achieve innovation, highlighting its crucial role as a shield of the past and engine for the future.
