Case Study: Wikimedia Deutschland achieves secure, data-sovereign collaboration with Mattermost

Wikimedia Deutschland improves cross-team communication with Mattermost

Wikimedia Deutschland, a Wikimedia chapter with over 100,000 members, needed a central collaboration platform to connect its core team and a global community of volunteers. Their previous tools, email and Google Chat, lacked the persistence and structure required for a large, distributed team, prompting their search for a new solution from Mattermost.

By self-hosting Mattermost, Wikimedia Deutschland gained data sovereignty for GDPR compliance and a secure, unified communication hub. The solution significantly improved cross-team communications and was extended with plugins to streamline workflows. Mattermost became the central tool for daily collaboration, enabling the team to connect over both work and personal interests.
