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.
- 1Where 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. - 2Does 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. - 3Who 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. - 4Are 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. - 5Can 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.
Every response links to the exact source passage.
Q&A and multi-step workflows on one platform. What's the difference?
Domain experts build and deploy — no engineers required.
SSO, RBAC, and full audit trails on day one.
Swap foundation models per agent without rebuilding.
Workspace, white-labelled in your product, or via API.
