In this chapter, living labs are perceived as open networks through which new innovations can be developed. The study deals with innovation in the public sector and examines renewal of well-being services for citizens in a regional context, such as establishment of a social enterprise for mental and addiction rehabilitees; use of a service robot in public elderly care; new ways for dentists to increase participation of teenagers in dental care. Using a multiple case study design, a cross-section of 14 living lab initiatives in Lahti (Finland) is analysed and the outcomes presented. Four different outcome categories are identified and analysed: access, windows, new solutions and new capabilities. Specific attention is given to outcomes for utilisers. Furthermore, the results contribute to an improved understanding of regional living lab activities and key conditions for their success, as well as the success of public sector health services, often as an institutional innovation.
