Open source, now & always

In 2011, Mattermost was founded as SpinPunch, a developer of an HTML5 game engine. Over time, the messaging solution the team was using became increasingly frustrating. After deciding to move to a new solution only to find out they were locked into the vendor’s ecosystem, the company repurposed its in-game messaging tools into Mattermost. Since 2015, Mattermost has been building an open core platform supported by a vibrant community of tens of thousands of contributors spread out across the world.
