<jats:title>Abstract</jats:title><jats:p>Over‐urbanization poses important challenges—both for citizen well‐being and quality of life, and for the sustainability of our planet. Traffic, accidents and pollution are just a few of the problems facing people living in cities. The need arises, then, to foster sustainable urban planning and management using, among other elements, smart solutions. In such a context, we would do well to reflect on effective economic, social, and environmental policies aimed at achieving sustainable cities and high quality of life for urban inhabitants. This article presents the most relevant aspects of the #eCity‐Sevilla project, a successful case of a sustainable public‐private innovation ecosystem. To this end, we take the Quintuple Helix Model as our reference, with a view to identify project stakeholders and better understand their relationships and objectives. Our data derives from secondary sources as well as from a set of in‐depth interviews with key informants. In the final section, the main theoretical and practical implications of our study are discussed.</jats:p>
