Sovereignty is who controls the computation.
Owning where a model came from is one kind of sovereignty. We focus on the other: control over the data and the computation itself, guaranteed by cryptography rather than by whose cloud it sits in.
Control you can prove, not control you're promised.
Control over the data and the computation itself, guaranteed by cryptography rather than by who trained the weights or whose cloud they sit in. Once the data is sensitive, that distinction is the whole game.
One primitive, every scale.
The same cryptographic privacy that protects one person protects a hospital, a bank, and a state. Nothing about the guarantee changes as the stakes grow. Only the size of the perimeter does.
The individual
You aren't the product. Your data, your keys, your agent. Personal AI that works for you without harvesting you on the way.
personal · self-custody
The enterprise
Regulated data stays inside the boundary you draw. Inference runs where compliance needs it to, with a receipt for every call.
regulated · audited
The nation
Digital sovereignty without depending on a foreign cloud or a single hardware vendor. Citizens' data stays under your own law.
public sector · residency
The agentic economy
Autonomous agents that act and transact on your behalf, and can prove they did it without leaking who you are.
agents · beyond
One method underneath all four: inputs secret-shared across parties that can't collude, computed on in that form, and returned with a proof. Sovereignty stops being a slogan and becomes something you can check.
Sovereignty without privacy is theatre.
If someone else can read the inputs, they hold the real control, whatever the org chart or the contract says. Privacy is what turns a claim of sovereignty into something that actually holds.
Control follows access
Whoever can see the computation can shape it. Real sovereignty starts by making sure no one else can see it in the first place.
Math over policy
A no-logging policy can be changed, breached, or subpoenaed. A secret-sharing guarantee holds because of how the math works.
Verifiable, not asserted
Every inference comes back with a proof. You don't have to take our word for it, and neither does your regulator.
A threat model you can state out loud.
Security here isn't a wall of certifications. It's a set of properties you can name, check, and argue with, plus the single assumption they rest on.
Operator-disjoint
Computation is split across parties run by different operators, so no single one can reconstruct your data.
No plaintext leaves
Inputs are secret-shared on the way in and stay that way throughout. Nothing recoverable crosses the boundary.
Open to inspection
Altaica-Mesh is public. Bring your own security team and audit the method instead of trusting a brochure.
STARK-attested
Each call carries a proof of correct execution that anyone can verify without us in the loop.
You hold the keys
Custody stays with you. Access is yours to grant, and yours to take back.
Stated, not hidden
The guarantee holds under an honest-threshold, non-collusion assumption. We name it plainly rather than bury it.
Control that leaves a record.
Governance is the part boards and auditors actually live in. On zkAGI it isn't a binder of good intentions. It's the same receipts and perimeter controls, surfaced for the people who answer to regulators.
Every call, an artifact
The verification receipt is a governance record: tier, recovery bound, egress, and proof, all kept for the audit.
Policy as configuration
Set the tier and the perimeter per workload. Your rules live in the request, not in a slide.
Residency by design
Pin compute to a jurisdiction so data stays inside one legal boundary, whether on-prem, regional, or across regions.
Mapped to the rules
Receipts line up with HIPAA, GDPR, and the EU AI Act, so each control points at a real obligation.
Who ran what
Every inference is attributable and provable after the fact, giving you accountability without a central log you have to trust.
Granted and revoked
Access and keys rotate on your schedule. Sovereignty includes the right to take it back.
The same machinery, pointed at sovereignty.
None of this sits apart from the product. The trust tiers, the perimeter you define, and the Explorer are exactly what make sovereign AI real at any scale.
Swiss governance. A neutral home for sovereign data.
zkAGI is governed by a Swiss Association, in a jurisdiction known for neutrality and precision. The guarantee holds wherever the compute runs, the team operates across the EU and APAC today, and the path leads to a dedicated Swiss AI lab your legal team can already trust.
Decide who stays in control. Then prove it.
Sovereign AI isn't a service you buy. It's a protocol you run. Choose who keeps control, set the tier and the perimeter, and the system proves it on every call. The data never leaves the boundary you drew.
