Private AI Infrastructure for Europe

AI Infrastructure
You Own

We design, deploy, and operate private GPU infrastructure for organisations across the UK and Europe, inside your own country's jurisdiction or on your premises. You own the cluster. We run the platform. Your data never enters a foreign public cloud.

The shift

Who really controls your AI stack?

The question that stays

The buyer's question moved from "where does our data sit" to "who controls the stack". When you rent AI from a foreign hyperscaler, you inherit its jurisdiction, its rules, and its pricing. These pressures are not a passing deadline. They keep growing.

Control

Foreign-cloud exposure

A provider under another country's laws can be compelled to hand over your data, wherever the servers physically sit. Jurisdiction follows the operator, not the rack.

Regulation

The bar keeps rising

GDPR, UK GDPR, the EU AI Act, and sector rules keep tightening expectations on data governance, audit logging, and human oversight. The direction of travel is one way.

Cost

Unpredictable bills

Metered hyperscaler pricing and egress fees turn AI into a moving target your finance team cannot defend across a multi-year plan.

What we do

We design, deploy, and operate it. You own it.

End to end

We deliver the parts, stand up the platform, and run the operations. One team owns the outcome, from first architecture to round-the-clock NOC, while the cluster itself stays yours.

1 · Architecture

Design

A non-blocking GPU, storage, and network architecture engineered around your workload profile, density, and growth plan.

2 · Build

Deploy

Containerized and air-gapped, racked under your own jurisdiction or on your premises, then validated end to end.

3 · Operate

Operate

Continuous monitoring, tuning, and lifecycle management through the OnePlus™ platform, so your team ships AI, not tickets.

Sovereignty by architecture

Sovereign by how it is built, not by where it is marketed.

A property of the design

Sovereignty is not a logo. Because the infrastructure is private and owned by you, and lives under the jurisdiction you answer to, there is no foreign cloud operator in the chain to be compelled, and no shared tenancy to leak across.

Your jurisdiction by default

Deployed in your own data center, in our or a partner facility under your national law, or on your premises. Your data stays where the law you answer to applies, whether that is UK, EU, or your home market.

You own it outright

The cluster is your asset, not rented capacity. We deliver the components, you hold the keys, and we manage it on your behalf.

Air-gapped and isolated

Containerized, air-gapped, single-tenant environments built to SOC 2 controls. No noisy neighbors, no shared control plane.

Compliance-ready foundation

GDPR and UK GDPR aligned by design, with data governance, audit logging, and human oversight built into the platform you run.

Economics

Predictable cost, owned outright.

Plan years, not months

Hyperscaler AI bills move with usage and punish you on egress. Owned, dedicated infrastructure turns a volatile operating line into a planned asset your finance team can defend.

Fixed per GPU

Stable pricing replaces metered, unpredictable invoices. Plan years ahead, not months.

Zero egress traps

Move data in and out of your own cluster without per-gigabyte penalties shaping your architecture.

An asset, not rent

The hardware is yours and sits on your books, rather than disappearing into a monthly subscription.

Who it is for

One platform for every regulated industry.

Same solution underneath

Dedicated compute and GPUs for AI training or inference, deployed under the compliance regime your sector demands. We map the controls; you run the workloads.

Healthcare & Life Sciences

Clinical AI, diagnostics, and imaging on isolated infrastructure with full control over where patient data is processed.

GDPRHIPAA-ready

Universities & Research

HPC-grade GPU clusters with multi-tenant workspaces for faculty, postdocs, and students, without cost surprises.

HPCMulti-tenant

Financial Services & FinTech

Risk, fraud, and modelling workloads on dedicated infrastructure aligned to operational-resilience and data-control rules.

GDPRUK GDPRDORA-aligned

Pharma & Biotech

Drug-discovery and clinical-data pipelines with protected IP, kept inside environments you fully govern and audit.

GxP-awareGDPR

Government & Public Sector

Air-gapped, single-tenant clusters under national jurisdiction for sensitive workloads, with NIST 800-171 / CMMC-aligned controls.

Three fabrics, one cluster

A production AI cluster is not one network. It is three fabrics, each tuned for a different traffic profile, designed independently and deployed as one coherent system.
