SOVEREIGN AI

The legal foundations for transatlantic AI data flows are eroding faster than most teams realise. We help you move your AI onto infrastructure you actually control.

“We use their London region” is not a sovereignty strategy. If your AI provider is a US company, the CLOUD Act means US authorities can compel data disclosure regardless of where your servers sit.

// THE_IDEA

The alternative is now real. Open-weight models match last year's frontier. Sovereign infrastructure exists across the UK and Europe. For the first time, you can run production AI — agents, memory, the full stack — without a single byte of data leaving your jurisdiction. The legal frameworks can be revoked faster than you can migrate. We help you audit your exposure and make the move before the risks become reality.

// THE_FOUR_BIG_QUESTIONS

The Four Big Questions

01

// CAPABILITY

Can open-source AI models match the performance of frontier APIs like GPT, Gemini and Claude?

Open models today typically match or exceed the frontier performance of 12 months ago. If you need the absolute bleeding edge — the capability that shipped last week — frontier APIs still lead. But the real question is: do you? Most enterprise workloads don't need today's frontier. They need last year's frontier, reliably, on infrastructure you control. That's exactly what open models now deliver.

02

// JURISDICTION

Does choosing a cloud provider's UK or EU region protect my AI data from US jurisdiction?

No. What matters is where the company is incorporated, not where the server sits. The US CLOUD Act means a US-headquartered provider can be compelled to hand over data regardless of which region you chose. Server location is a networking decision. Corporate jurisdiction is the legal one.

03

// STABILITY

Are EU-US and UK-US data transfer frameworks at risk of being invalidated?

It's already happening. The executive orders underpinning EU-US and UK-US data transfer frameworks can be amended faster than legislation. PCLOB oversight has been gutted. Autopen-signed EOs — executive orders signed by machine rather than by hand — are being challenged as invalid. Teams relying solely on the current adequacy regime are building on ground that is actively shifting — sovereign infrastructure is the hedge.

04

// COST

Is running AI on sovereign infrastructure more expensive than using cloud APIs?

The cost equation has flipped. Open models have eliminated licence fees. Neoclouds have driven GPU pricing down 60%+ in two years. The real question is whether you can afford the alternative: a compliance incident, a forced disclosure, or a midnight scramble to migrate when the legal basis you relied on gets invalidated.

Half-Day Assessment

Sovereign AI
Readiness Assessment

A half-day session with your AI and data teams to review your current stack — models, infrastructure, data flows, and vendor agreements. The output is a clear picture of your sovereignty exposure and a prioritised action plan to close the gaps.

01

Audit your current AI stack

Which providers, what data flows through them, where it lands, and under whose jurisdiction.

02

Identify sovereignty risks

CLOUD Act exposure, restricted transfers, data retention gaps, and single-vendor dependencies.

03

Deliver a prioritised action plan

What to fix now, what to migrate, and what you can leave. Practical steps ranked by risk and effort.
