Sovereign —
and provable.
100% UK founder-owned. No foreign parent, no foreign capital, no US platform dependency — and cryptographically provable. Every company in this market says "sovereign". This page sets out why, for NquiringMinds, it is a verifiable property rather than a marketing register — and how to check each claim yourself.
Ownership
100% UK founder-owned.
No foreign parent, no foreign capital, no external controlling interest. Ownership is a matter of public record at Companies House — not a press-release claim.
Capital
No overseas venture capital on the cap table.
Growth funded by revenue and UK programmes. No investor jurisdiction can compel access, licensing or export of the technology.
Intellectual property
IP created, registered and retained in the UK.
Patents and standards contributions filed under UK ownership. No offshore licensing structures; the UK entity controls the entire stack.
People
UK-based engineering team.
Engineers and architects based in the UK, with SC-cleared staff available for classified programmes.
Platform dependency
No US platform dependency.
Volt4 is C++ native and self-hosting — it runs on-premises, at the edge, or in any cloud, with no mandatory third-party platform, service or licence in the delivery chain.
Supply chain
Cryptographically verifiable supply chain.
TAIBOM (Trusted AI Bill of Materials) instruments every component — code, models, weights and data — with signed, checkable provenance. This is the part no attestation letter can match: you can verify it yourself.
Sovereignty claims usually rest on attestation — a letter, a badge, a policy document. Volt4's rest on cryptography. The same primitives that make the platform a verifiable trust fabric make its own supply chain checkable:
- Signed data — every artefact carries a W3C Verifiable Credential; provenance is checked, not asserted.
- TAIBOM supply-chain assurance — a signed bill of materials across code, models, weights and training data.
- Distributed policy — declared, auditable control over who can reach what, enforced locally rather than by a foreign-operated gateway.
- Standards authorship — NIST SP 1800-36, TAIBOM, IoTSF, OMTP TEE. We don't just build to spec — we write it.
