Mattermost is a leading provider of secure open-source collaboration solutions, specifically designed for technical teams in highly regulated environments such as DevOps, finance, and national defense. Founded in 2016 and headquartered in Palo Alto, California, the company employs around 160 people and offers a powerful alternative to proprietary SaaS platforms. The platform is based on a "thin open core" model and combines real-time messaging, voice and video calls, and screen sharing with advanced workflow automation and AI-powered bots. A key advantage of Mattermost is maximum deployment flexibility: organizations can self-host the software, run it in a private cloud, or install it in physically isolated (air-gapped) environments. This guarantees complete data sovereignty and operational control. Security and compliance requirements are met through support for standards such as ISO 27001, SOC 2, and GDPR. Mattermost enables highly sensitive industries to collaborate efficiently without compromising on data security.
