<p>Despite widespread recognition that an enterprise’s critical resources may extend beyond its traditional boundaries, a thin layer of empirical research has investigated the dynamics of international new ventures (INVs) in leveraging network strategies for rapid international growth. This study addresses this gap by elucidating the evolution of operational value networks that firms construct and manage during their internationalization processes. Data were collected from five nascent European INVs via a qualitative exploratory case-study methodology. The paper’s main contribution lies in gauging network evolution during the internationalization process and offering insights into the structure and interactions of INV network management. It contributes to informing our understanding of the information and knowledge flows that play a special role in the strategic management of the network of INVs. The structural factors were analyzed by looking at the type of ties forming the network and its size, density, or sparsity. The interactional network factors considered the type of relational exchanges INVs adopted during the internationalization strategies. This latter aspect was analyzed to reveal the impact of internal and external information and knowledge flows considering the type of activity (data-driven or human-led) and mode of expansion (explorative or exploitative). Seventeen propositions are articulated, contributing to the extant literature by shedding light upon how network management in young INVs evolves over time, aligning with their internationalization learning trajectories and growth phases. These findings underscore the dynamic nature of network strategies in facilitating the rapid international expansion of INVs and provide a nuanced understanding of the strategic management of knowledge and information flows within these networks.</p>
