Abstract
The paradox that unifies cooperation and competition may be at the root of several tensions (Gnyawali and Park, 2009). The multiplication of partners enhances both coopetition complexity and the tensions related to that multiplication. Consequently, the management of tensions is essential for coopetition to evolve over time. Our exploratory study investigates a case of horizontal multiple-firm coopetition to understand the evolution of tensions and their management. In this article, we identify the paradoxical tensions of coopetition as they develop over time and the related risks. The coopetitors multiply their coopetition strategies to overcome tensions. Additionally, we note that the management of paradoxical tensions contributes to the evolution of coopetitive relationships and allows partners to benefit from coopetition opportunities. Last, the case reveals the existence of a coopetitive portfolio for coopetitive managers.
