However, besides mastering technical challenges, achieving economic viability and broad market success has so far proven to be difficult for these initiatives. Based on a publicly funded research project, this study focuses on the business model design for an open digital ecosystem for privacy friendly and trustworthy intelligent assistants. We present how the agent-based modelling technique can be employed to evaluate how business models perform in various constellations of an open digital ecosystem. Thus, our work relates to the strategic choice of suitable business models as an important success factor for privacy and security-relevant technologies.enagent-based modellingbusiness modelssmart assistantsecosystemdiffusionText/Conference Paper10.18420/ois2020_091617-5468
