A European AI platform built to be secure, sovereign, and sustainable.
Melious brings the scattered pieces of European infrastructure into one accessible platform, and runs the best open-weight models on top of it. We go further than just running them: you get everything you need to put AI to work in your business, fully sovereign and true to our values. As open-weight models get better, so do we, building the systems that push them further. European AI, without compromise.
European AI that stands on its own. That's what we're building.
Your data stays under European jurisdiction. No foreign government access. No loopholes.
End-to-end encrypted, then one more layer on top. Your data never leaves trusted European providers, and we never train on it.
See where your data goes, which models run, what it costs, and what it emits. Full visibility, always.
Our infrastructure partners run on low-carbon energy. What's left, we offset, making us effectively CO₂-neutral.
It started with a simple question: Why is Europe building its AI future on American infrastructure?
In late 2024, our CEO Simon hit this wall while integrating AI in sensitive environments. He shaped the idea and brought it to the team. We founded Melious in summer 2025 and built the foundation for what it is today.
What began as an idea in the southwest of Germany became a company. Four founders, each owning a different part of it.
60+ open-weight models, sovereign European AI, one API key.
We're still early, and that's the exciting part.
If you care about European tech and want to build something that matters, we'd love to hear from you.
