Purpose This paper examines how interorganizational strategy processes unfold by analyzing cross-level decision-making challenges that recur when organizations jointly develop strategy while remaining embedded in their own organizational contexts. Design/methodology/approach We conducted a longitudinal qualitative case study of an interorganizational strategy process focused on a collective bridge inventory in a Dutch region. We followed an initiative for approximately one year, starting from its early formation. Using a layered analytical approach that distinguishes interpretation, structure and relations, we traced how the initiative transformed over time across organizational boundaries. Findings The study identifies three cross-level strategizing challenges: joint goal setting, shared ownership and pacing. These challenges did not appear as linear stages or discrete obstacles but repeatedly re-emerged. Joint goal setting was complicated by divergent organizational rationales, shared ownership emerged unevenly across actors and pacing reflected persistent temporal misalignments between interorganizational ambitions and intraorganizational capacities. Together, these cross-level dynamics shaped the trajectory of the strategy process. Practical implications For practitioners, we propose viewing these challenges as interpretive lenses to make sense of re-emerging tensions and diagnose when the strategy process may require temporary stabilization. Rather than designing “linking pins”, strategizing requires a continuous balancing effort between inter- and intraorganizational rationales. Originality/value The paper contributes to interorganizational strategizing research by conceptualizing cross-level challenges as dynamic and constitutive elements of strategy processes rather than background conditions. It offers a rare, in-depth, processual account of informal and horizontal interorganizational strategizing in response to complex societal challenges, extending open strategy research beyond the focal organization.
