The sovereign AI ecosystem behind ESAI

The European Sovereign AI Cloud · by Combell, delaware and imec

Your AI. Your data. Your control.

Every AI-driven company carries three hidden risks: shadow AI nobody controls, token costs that grow every month, and data that quietly leaves the EU. The fix is one move: run your own sovereign AI cloud. A forty-five minute talk maps your usage, your risks and your savings: routing first, hardware when the maths says so.

The partnership

Three partners. One integrated offering.

Designs and runs it

Builds and operates the environment, including the AI gateways with budgets, personal-data filtering and a full audit log. Your single point of accountability from AI strategy to daily operations.

Hosts it

Provides the dedicated GPU servers in European datacenters. Combell, part of team.blue, runs them 24/7 as its own business-critical infrastructure: fully managed, with a predictable capacity fee instead of a per-token bill.

Measures and optimises it

Tests models on your own documents, code and agents with its aistack benchmarking environment, then tests and optimizes models and infrastructure against the customer's workloads, comparing quality and cost.

The frontier playbook

Flat-rate seats built the habit. Now the meter runs.

Years of cheap, all-you-can-use plans made your whole company dependent on ChatGPT, Copilot and Claude. Now the pricing flips to per-token meters that scale with your success: the more your teams rely on AI, the more you pay for exactly the same work. There is a way out: bring the habit home.

Shadow AI

Personal subscriptions, free chatbots, browser extensions. Useful work happens outside every policy, audit trail and procurement process, until something leaks.

Data control

Every prompt to a US-frontier endpoint carries context: customer names, contracts, code. GDPR and the AI Act both ask where that data went, and who saw it.

Cost control

AI token usage is the rising budget line in many enterprises. Match the right model to the right task and make the switch to the best deployment mode to ensure cost predictability: for APIs, cloud or on prem infrastructure.

Six questions to your sovereign setup

Every “no” identifies a gap to address. At the end you see the sovereign hardware that fits your size: real contracts, no per-token meter.

Question 1 of 6

1 / 6

Question 01 · Shadow AI

Are you certain no company information is being posted to personal AI accounts such as ChatGPT or Claude?

Most leaders answer “probably not”. Whatever finds its way into a personal chat stays outside every policy and audit trail.

Question 02 · Cost visibility

I have a complete view of my employees' enterprise AI accounts (who uses what, in which departments, at what cost), and that spend is under control.

If you can't name your Claude seat count per department from memory, the answer is no.

Question 03 · EU data residency

I am certain that no data leaves the EU zone through any of these AI interactions.

Personal accounts, browser extensions and unlogged API calls make any honest answer “no” by default.

Question 04 · Approved channel

There is one approved, logged way for employees to use AI at work, and people actually use it.

If the sanctioned route is harder than opening ChatGPT, work quietly moves around it.

Question 05 · Sensitive data

Customer data, contracts and code only reach AI tools we control and approve.

One unapproved browser extension is enough to leak context you can't audit.

Question 06 · Bill surprises

Our AI spend matched what we expected this quarter, with no surprise invoices.

Per-token meters grow with your success; duplicate seats hide in different cost centres.

FAQ

Sensible questions

What are AI gateways?

One governed entry point for every AI request in your company. Copilots, agents, developer tools and business apps all talk to a single endpoint, compatible with the OpenAI and Anthropic APIs, so existing tools connect without a rewrite. Per request, the gateway decides which model may handle it, applies your policy and logs who did what.

Who is behind ESAI, and who does what?

Three partners, one accountable offering. Combell, part of team.blue, provides the dedicated GPU servers in its European datacenters. delaware designs and operates the environment, including the AI gateways, and is the single partner accountable from strategy to daily operations. imec tests and tunes the models on each customer's own use cases, with its aistack environment, so that model selection becomes an engineering decision instead of a gamble. Together that gives you capacity that is European in ownership, certification and management.

Can't we simply ban ChatGPT and personal AI accounts?

You cannot ban shadow AI. Almost half of the people using generative AI at work still do it through personal accounts, outside every policy and audit trail. What works is making the sanctioned path the easier one: good models, one login, no friction. Then usage moves onto the gateway by itself.

Does our data leave Europe?

Not for anything that matters. Your private AI runs on dedicated capacity in European-owned data centres and models, prompts and logs stay inside your perimeter. Frontier models are only used for non-sensitive work, only when your policy allows it, and personal data is filtered out first.

Are open models good enough?

For most work, yes. On coding, the best open-weight models now sit within a few points of the frontier. For the hardest reasoning, frontier models still lead. That is exactly why the gateway routes per task instead of standardising on one model, and why you can switch centrally the moment a better model appears.

Is it safe to run open-weight models, including Chinese ones?

Model weights are numbers, not software: a model file cannot run code, open a connection or report back. On air-gapped capacity there is simply no way out. What remains is trained behaviour, such as bias in how a model answers, so every model is tested before it goes live and the gateway applies your policy on top.

How does this help with the AI Act, NIS2 and DORA?

Governance is becoming a legal duty, and the gateway helps organizations document compliance with the AI Act, NIS2 and DORA. It keeps a log of every AI request, enforces a policy per model and use case, and gives evidence of where your data was processed. That is the material your auditor asks for.

Do we have to replace our current AI tools or our Microsoft landscape?

No. The gateway sits in front of the providers you already use, so teams keep their tools while you gain the view and the control. It is an extra lane next to your Microsoft landscape, not a replacement, and if you run fully on Azure, the same governance layer runs on Azure API Management.

Is moving from a closed API to my own more expensive?

On the contrary. Moving towards your own environment provides cost transparency as you're not dependent on changing token-based pricing models. You lease the infrastructure and we make sure that you get the most tokens out of that infrastructure. In our first deployments, we saw cost savings of up to 50%

How do we get started?

With the online assessment tool, working from your own figures: it shows today's AI cost, a 24-month projection, the possible savings and the point at which owning capacity pays off. The gateway can then stand in front of your existing AI providers and sovereign capacity is added once your volume justifies it.
