Bringing to success an open-source project is hard, but growing it from an organizational and business point-of-view, organically to the growth of the community, their enthusiasts, and the contributors is an equally interesting challenge for all the companies behind. Growing the maintainers accordingly with the scale of contributions and support, managing the business expectations with the expectations of the open source (and not paying) adopters, growing the product accordingly, those are only some of the topics that every mature Business Open Source organization discusses (on a recurrent basis I would say). In this talk you will learn more about these challenges through practical examples based on the direct experience after having worked directly with several, structured, successful, worldwide, Business Open Source organizations in community-driven projects.
