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

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.

Nextcloud is the world’s most popular privacy-focused collaboration platform. It is used by tens of thousands of private and public organizations and tens of millions of private individuals to stay in control of their sensitive data and ensure privacy compliance.

Founded in 2016, Nextcloud is fully employee-owned and has grown organically ever since. Learn more at www.nextcloud.com.

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.

With Nextcloud, users can edit and share documents, chat and hold videoconferences, and manage emails, contacts and calendars via easy web and mobile apps. The open-source software has a modular design and can be extended with hundreds of apps. It runs in on premises in a private cloud or with a trusted provider.

“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.”

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.
