Contributors are individuals whose voluntary and free activity consists of bringing a productive part to a common work where the market is peripheral. The marketing literature allows them to be described as prosumers (Ritzer and Jurgenson, 2010), that is to say involved in a complex arrangement of production and consumption. Understanding the experience of contributors shows that freedom of engagement is not a barrier to joint production, even if it is difficult for an organization to manage this resource. The results make it possible to describe the self-sustaining dynamic that leads contributors in a quest for positive experiences (Csikszentmihalyi and Nakamura, 2014). The latter allows contributors to access a state of flow or relaxation, then encourage the repetition of experiences. Through a comprehensive approach, this paper strengthens theoretical knowledge about a common form of prosumption and invites us to continue understanding the mechanisms favoring the support of contributors.
