Private and Self-Hosted AI for Sensitive Data

AI that runs on your infrastructure, not someone else's

Private AI means running the model on infrastructure you control, your own servers or a UK or EU cloud, so your data is processed in-house and never sent to a third party's API. Self-hosted open models have caught up: for a great many business tasks, an open model running on your own hardware now does the job a commercial API would, without the data ever leaving the building.

For some businesses, the usual way of adding AI is a non-starter. Sending customer records, case files, or commercial data to an external API is a compliance problem, a confidentiality problem, or simply a risk you are not willing to take. The standard answer, use the big cloud AI and trust the contract, does not satisfy a regulator or a nervous client. Private AI removes the question by keeping the data where it already lives.


Why run AI privately

The case for private AI is rarely about the model and almost always about the data around it. These are the reasons businesses choose it.

Data never leaves

Sensitive records are processed on your infrastructure, so there is no third party to trust and nothing to leak in transit.

Compliance you can evidence

For regulated work in health, legal, or finance, "the data stayed on our servers" is an answer a regulator accepts.

No training on your data

Your information is never used to improve someone else's model, because it never reaches them in the first place.

Predictable cost

Your own hardware is a known, fixed cost rather than a per-call bill that climbs with every use.


The open models are good enough now

This used to be a painful trade-off: privacy or capability, pick one. That has changed. Open models you can run yourself now match the commercial APIs closely enough for most business tasks (extraction, drafting, classification, search over your own documents), on hardware that costs less than a single member of staff. We will tell you honestly where an open model is as good as the cloud one and where it is not, so the decision is made on facts rather than fear.

Privacy without the capability tax. Open models on your own hardware now handle most business AI tasks well, so keeping data in-house no longer means settling for less.


How it runs

Not everything needs to be private, so we start by separating what does from what does not. Often the right answer is a mix: private for the sensitive work, cloud for the rest.

1

Work out what needs to stay private

Which data and which tasks genuinely require it, because forcing everything in-house when it does not need to be just adds cost.

2

Choose the model and the hardware

The right open model for your tasks, and infrastructure sized to match, on your servers or a UK or EU cloud you control.

3

Build it into your systems

The AI features or agents you need, running against the private model, connected to your data with proper permissions.

4

Run and maintain it

Updates, monitoring, and model upgrades as better open models arrive, so it stays current without you having to mind it.


Who it is for

Private AI is worth the extra setup when the data genuinely cannot go to an external service.

You handle sensitive data. Health, legal, financial, or personal records that carry real consequences if they leak.
Someone requires it stays in-house. A regulator, a contract, or a cautious client will not accept the data leaving your control.
You want AI but cannot use the cloud one. The benefits are clear, but sending your information to an external API is off the table.
Your usage is heavy. Enough that a per-call bill is becoming the bigger cost and owning the hardware starts to pay.
Your data is not sensitive and volumes are modest. Then a commercial API is simpler and cheaper, and we will say so rather than sell you hardware.

Where it fits

Private AI is the "where" for the rest of our AI work: the AI features and AI agents we build can run against a private model just as well as a cloud one, so sensitive data stays put. It is the practical end of digital sovereignty: owning not just your software but the AI that reads your data, and the infrastructure it runs on.
