Abstract
This research identifies business models (BM) adopted by editors of free and open source software. These models require an original BM approach because the value creation depends on the project attractiveness on contributors whose number, quality and diversity are not controlled. This specificity raises the question of how sharing a value that cannot be anticipated or formally negotiated. We carry out a quantitative analysis of nearly 200 software and perform a taxonomy using the TwoStep Cluster method. Our results reveal four BMs, commitment, exploration, expertise and optimization.
