In a cloud landscape dominated by centralization, Nextcloud stands out for what it refuses to do. The company’s Founder and CEO, Frank Karlitschek, makes it clear: Nextcloud will never host your data. Instead, it is built on a federated, decentralized model that gives users and partners full control.

In this TFiR clip, Karlitschek explains that while Nextcloud collaborates with major cloud providers such as AWS, Google Cloud, IONOS, and OVHcloud, it maintains a strict boundary between partnership and ownership. “We don’t want your usernames, passwords, or metadata,” he says. “We give you the software and the freedom to deploy it where you trust.”

That distinction defines Nextcloud’s philosophy. While many open source companies eventually move toward centralized SaaS models, Nextcloud doubles down on user empowerment. Its partner network allows customers to run managed instances on trusted infrastructure while keeping their data private. Governments, universities, and enterprises across Europe increasingly choose this model to meet compliance and sovereignty requirements.

Karlitschek’s commitment to decentralization isn’t just a business strategy — it’s a belief system rooted in open source values. By separating software delivery from data ownership, Nextcloud ensures transparency and independence for every user. It’s a stark contrast to hyperscalers’ “all-in-one” approach, where convenience often comes at the cost of control.

As global debates over data sovereignty intensify, Nextcloud’s federated model may point toward a more ethical and sustainable future for the cloud industry — one that balances functionality, openness, and privacy.
