From Game Engines to Secure Communication: The Surprising Rise of Mattermost

Mattermost began not as a communication platform, but as a solution born from frustration within the gaming industry. Originally part of SpinPunch, an HTML5 game engine developer, its messaging tools were repurposed when co-founders Ian Tien and Corey Hulen faced repeated issues with proprietary chat systems that locked away their data and offered no control. In 2015, they pivoted entirely, launching Mattermost as an open-source project designed for secure, self-hosted team communication. Unlike mainstream platforms like Slack, Mattermost offers users full control over their data, allowing organizations to host it on private servers behind firewalls, ensuring compliance, security, and autonomy. Its '"'"'open core'"'"' model provides a free, fully functional version while offering premium enterprise features for larger organizations with stricter security needs. This approach has sparked debate in the open-source community, with critics questioning whether locking advanced features behind paywalls compromises the spirit of open source. Despite this, Mattermost has seen widespread adoption across sectors including government, defense, healthcare, and finance. It powers internal communications for global entities like Siemens, supports mission-critical operations during emergencies, and enables secure collaboration in highly regulated environments. The platform'"'"'s extensibility allows integration with tools such as GitHub, Jira, and Jenkins, making it a favorite among technical teams. A vibrant global community contributes to its continuous evolution, submitting hundreds of improvements and features. Mattermost also embraces modern trends like AI-powered collaboration tools, aiming to enhance productivity without exposing sensitive data to external AI providers. With support for over 16 languages and scalability to handle up to 100,000 users, Mattermost continues to grow as a secure alternative for organizations prioritizing control, privacy, and customization. As it moves forward, Mattermost remains committed to bridging the gap between usability and ironclad security, ensuring that teams—whether managing patient records or developing next-gen tech—can communicate safely, efficiently, and independently.
