In this study we explore and analyse a virtual network-centred incubator model called the Water Innovation Accelerator (WIN). The incubator model has been designed and implemented in Sweden to enable and orchestrate water-related innovative solutions by connecting different players via organized networks. Framed by theory and research on open innovation, incubation models, and entrepreneurial networks we provide an overview of the overall design, management and organization of WIN. We also analyse and assess the working and performance of WIN with respect to its purpose to aid the development and market uptake of water related innovative solutions via its entrepreneurial network. Our findings offer theoretical and empirical insights to researchers, policy makers and incubation managers that may aid current and future efforts to accelerate water innovation. Copyright © 2016, Academy of Management
