Building the Trust Layer for the AI Era.

We believe that privacy should not be a policy, but a physical guarantee. Steleum is engineering the infrastructure where data can be processed without ever being exposed.

Radical Privacy

We don't trust "promises". We trust mathematics and hardware. If it's not encrypted in RAM, it's not private.

Swiss Neutrality

Our HQ is in Zurich for a reason. We operate under the world's strictest data protection laws (nFADP), free from foreign interference.

Developer Velocity

Security shouldn't slow you down. We build tools that allow engineers to deploy confidential workloads in minutes, not months.

Heart of Europe.

Steleum is headquartered in Zurich, Switzerland. We are part of the "Crypto Valley" ecosystem, surrounded by the world's leading privacy engineers and financial institutions.
