Cortex

The Sovereign AI Platform for European Enterprises

Sovereign by design. Not by settings toggle. A Swiss company, an ETH Zürich spin-off, operating on European infrastructure — with a simple contract-level promise: your knowledge is yours, stays yours, and never trains anyone else's model.

What "sovereign AI" actually means

Strip away the marketing and sovereignty comes down to five testable questions. Ask them of any AI vendor — including us.

  1. 1
    Where does the data live?

    The test: Can the vendor name the jurisdiction your data is stored and processed in — and keep it there?

    Cortex: EU data residency, operated by a Swiss company. Your documents, indexes, and agent configurations stay in the EU. GDPR compliant; SOC 2 in progress.
  2. 2
    Does your data train someone else's model?

    The test: Is "we don't train on your data" a contractual guarantee, or a configurable default that can change with the next terms update?

    Cortex: Contractual guarantee. Your knowledge never trains a public model. Ever. This is the foundation of the platform, not a privacy setting.
  3. 3
    Who owns what you build?

    The test: If you build agents, workflows, and knowledge products on the platform — do you own them? Can you white-label, license, sell them?

    Cortex: IP ownership by design. The agents you build are yours: white-label them, embed them in your own product, monetise them. Your methodology stays your competitive advantage.
  4. 4
    Are you locked into one model provider?

    The test: When a better or more compliant foundation model appears, can you switch — without rebuilding everything?

    Cortex: Model-agnostic by architecture. Choose the best foundation model per agent and swap without rebuilding. Sovereignty includes not being hostage to a single provider's roadmap or terms.
  5. 5
    Can you leave?

    The test: Exit rights. Can you take your data, your indexes, and your agent definitions with you?

    Cortex: Your sources remain your sources. No hostage data, no proprietary trap formats.

Why this matters now: the regulatory reality

European organisations aren't asking about sovereignty out of preference — the regulatory environment demands it.

  • GDPR

    Governs where personal data in your knowledge base can flow and who can process it. US-hosted AI tools add transfer-mechanism complexity your DPO has to defend.

  • The EU AI Act

    Phases in obligations for AI deployers, including transparency and documentation duties. Grounded, citation-backed systems with audit logs are dramatically easier to document than opaque ones.

  • Sector rules

    Financial services outsourcing guidelines, legal professional privilege, research-data agreements in publishing — often make non-EU processing a non-starter regardless of GDPR mechanics.

The practical consequence: procurement and legal review is where enterprise AI projects go to die. A sovereign-by-design platform turns a six-month legal negotiation into a checklist your counsel can sign quickly.

Sovereignty without sacrificing capability

The old trade-off was: sovereign or state-of-the-art. Cortex refuses it.

Swiss roots, European reach

Uthereal is an ETH Zürich spin-off, built in Switzerland and backed by Innosuisse and top Swiss research institutions. Switzerland's neutrality, privacy tradition, and data-protection framework are part of why customers trust us with their most valuable asset.

Frequently asked questions

A sovereign AI platform gives an organisation control over the five dimensions that matter: where data resides, whether data trains external models, who owns what is built, which foundation models are used, and the right to exit with your data. A platform is sovereign by design when these are architectural guarantees rather than configuration options.

Yes. Cortex offers EU data residency and is GDPR compliant, with SOC 2 in progress. See our Trust Center for current documentation.

No. Your knowledge never trains a public model — this is a contractual guarantee.

Yes. Cortex is model-agnostic: select the best model per agent and swap without rebuilding your agents.

Private AI focuses on confidentiality — keeping your data unexposed. Sovereign AI includes privacy but adds jurisdiction (residency), ownership (IP), independence (model choice), and exit rights. Cortex delivers both.

The EU AI Act phases in obligations for deployers as well as providers, varying by use case and risk class. This isn't legal advice — but grounded systems with citations and audit logs make compliance documentation substantially easier. Discuss your specific case with counsel.
