Skeptical stakeholder involvement – collaborating with stakeholders who may harbor negative attitudes - is a complex, uncertain process that poses substantial challenges for innovation project management. Developing complex innovations like those in urban spaces requires engagement with knowledge, behavioral shifts, and resources from both public and private stakeholders. As a result, these stakeholders might oppose the project's objectives, thereby exerting a significant influence on the project. However, scant attention has been directed toward investigating the role of skeptical stakeholder involvement. The goal of this research is to address this research gap by examining the underexplored impact of skeptical stakeholder involvement on the project front end, thereby underscoring the importance of innovativeness and implementation intention as outcomes during these initial project stages. The study draws on a unique combination of text mining, text analysis, and survey data derived from 107 publicly funded urban innovation projects in Germany. These projects encompass diverse innovation types and technologies that may affect nearly all stakeholders within a given city district, thus making the context an ideal empirical terrain for investigation. The study's findings reveal that (i) skeptical stakeholder involvement positively influences innovativeness and implementation intention, and (ii) a robust reservoir of project management resources, coupled with moderate levels of formal management, facilitates the integration of skeptical stakeholders. The study advances current literature on project stakeholder management and project front-end dynamics by highlighting the positive influences of skeptical stakeholder involvement. Consequently, these outcomes contribute to the broader literature on sustainable urban transformation and enhance our understanding of stakeholder management mechanisms in the realm of urban innovation projects.
