Welcome to Chinstrap Community
Chinstrap Community promotes the understanding and adoption of commercial open source software (COSS) business models in the software startup community and the technology industry at large.
Why COSS?
COSS is a capital-efficient model for commercializing innovation that enables the users of a software product to participate in its development. This approach fosters organic growth while opening up new avenues for monetization.
