This article investigates data-related tensions and their corresponding coping strategies arising from inter-firm collaboration in digital servitization ecosystems. We conducted a systematic literature review based on thematic and network analyses, covering a sample of 191 articles on digital servitization. The findings offer a set of 11 tensions organized into six dimensions: (i) data strategy, (ii) data partnership governance, (iii) data reliability, (iv) data security and privacy, (v) data interoperability, and (vi) data lifecycle. Additionally, we identify seven coping strategies to address these tensions, which we categorized into three approaches: (i) governance, (ii) technology, and (iii) organization. These tensions and their corresponding coping strategies are arranged and presented in a conceptual framework, leading into five propositions. We also provide a research agenda outlining future research opportunities to expand knowledge on the tensions arising from inter-organizational relationships when creating and providing data-driven services. For practitioners, we offer insights into how to manage ecosystem relationships by suggesting strategies to cope with these tensions, and for policy makers we shed light on crucial matters for future data governance policies and laws.
