The integration of external data offers enormous potential for new and expanded value propositions for companies. However, organizations often refrain from sharing data as they expect detrimental consequences from it. This study provides insights into how organizations decide to share data within the ecosystem and what organizations can do to motivate other organizations within the ecosystem to share data with them. Using privacy calculus and ecosystems theory to sensitize a qualitative case study of the German orthopedic market, we derive three risks (weakening one’s position in the ecosystem, IT alignment investments, and penalties for data protection violations) as well as three benefits (increased value creation of the ecosystem, competitive advantage over other ecosystems, and gaining additional transactions) perceived by organizations considering to share data. Further, three strategies for obtaining data from other organizations are derived: mitigating the risks, emphasizing the benefits, and bypassing the calculus.
