	abstract = {This paper focuses on contributions of users in early phases of radical innovation projects. In a 
multiple case study analysis in the field of medical equipment technology, we identify 
characteristics of users who contribute substantially to the development of radical innovations 
by being their inventors and (co)-developers. These innovative users have high motivation to 
seek new solutions, possess a diverse set of competencies, and are embedded in a supportive 
environment. We furthermore observe that they play an entrepreneurial role as they establish 
and organize the required innovation networks. These innovation networks are needed to 
transform the users’ radically new concepts into first physical prototypes and marketable 
products. The study highlights how manufacturing firms can benefit from innovative and 
entrepreneurial users in the early phases of radical innovation projects.

We argue that this finding fits the economic incentives operating on users. Local need information will in general be the most relevant to user-innovators, since the bulk of their innovation-related rewards typically come from in-house use. User-innovators will increasingly tend to rely on local solution information as the stickiness of non-local solution information rises. When user-innovators do rely on local information, it may be possible to predict the general nature of the innovations they might develop.
