Nextcloud joins MariaDB Foundation as Silver Sponsor, strengthening the European open source backbone

We are proud to welcome Nextcloud GmbH to the MariaDB Foundation sponsor family as a Silver Sponsor. As the world’s most popular privacy-focused platform for secure file sharing, collaboration, and communication, Nextcloud stands as a pillar of digital sovereignty — a value that resonates deeply with MariaDB Foundation’s mission.

Built in Europe, trusted worldwide, Nextcloud is a champion of user-controlled data. By supporting MariaDB Foundation, Nextcloud affirms its commitment to a fully open, auditable, and sovereign technology stack—empowering users, businesses, and governments to stay in control of their data and avoid vendor lock-in.

“The collaboration with Nextcloud is a natural fit,” said Anna Widenius, CEO of the MariaDB Foundation. “Together, we represent a strong and growing European ecosystem that is committed not just to technological excellence, but to ethical infrastructure—where innovation, privacy, and sovereignty go hand in hand.”

Frank Karlitschek, CEO Nextcloud: “More than ever, users across the globe are looking for digitally sovereign solutions to increase their resilience. Open source projects such as MariaDB and Nextcloud are crucial to this. It is important to us to support the development of MariaDB and give users access to powerful sovereign tools.” 

Nextcloud’s support comes at a pivotal time, as the MariaDB Foundation finalizes its move to the EU and actively engages in initiatives around data sovereignty, digital commons, and strategic autonomy for public and private sectors alike.

We’re excited to deepen our cooperation and foster a thriving, independent European open source stack—one that protects freedoms while delivering performance at scale.
