No community grows in isolation. This talk explores how intentional partnerships can amplify the reach, visibility, and sustainability of open-source and developer communities. Drawing from experience building collaborations for community-driven tech initiatives and contributing to Mautic, I’ll share how to design partnership models that are mutually beneficial, helping communities gain resources, new contributors, and event support while offering partners authentic engagement aligned with FOSS principles. Attendees will walk away with a framework for identifying, pitching, and maintaining partnerships that strengthen both community and corporate allies without compromising values.
