Holm installs language models on a server in your building. Your team gets a private assistant, and your documents never leave the premises.
The usual answer is to ban the tools. Then people paste the contract in anyway, or the firm goes without.
So bring the model to your side of the water
Nothing crosses
The model, your documents and every answer stay on a machine in your building. It works with the network cable pulled out.

Holm is a server we build, bring to your office and switch on. It holds the model and a searchable copy of your documents. Point at a part to see what it does.
Three sizes
Example configurations. Yours follows the survey.
It answers from your files, and shows which ones
It reads what you point it at
Shared drives, a document system, a mailbox archive. You choose the folders, and you can take them away.
Every answer names its sources
Staff can open the page a sentence came from before they rely on it.
It respects who can see what
People only get answers from files they already have permission to open.
Which supplier contracts renew automatically before March?
- 1Marlow Freight MSA.pdf
- 2Tessel Hosting agreement.docx
- 3Supplier register 2026.xlsx
Two contracts renew automatically before March. Marlow Freight renews on 14 January unless you give 60 days’ notice, so the notice window has closed.1 Tessel Hosting renews on 27 February with 30 days’ notice, which leaves until 28 January to cancel.2 The register lists nine other suppliers, none with an automatic renewal clause.3
The models we install are open-weight models, the kind published by Meta, Mistral, Google and Alibaba. They are very good at the daily work of a firm. The largest cloud models are still bigger, and we say where that matters.
Someone asks
“Turn these meeting notes into a letter to the client, in our house style.”
What it does
Writes a first draft in seconds from your notes and your own past letters. Good at tone, structure and getting to the point.
Where it stops
It does not know facts that are not in the notes. A person still signs the letter.
Where a cloud model still wins
Open-ended research, the hardest reasoning and very large codebases. If your work is mostly that, we will tell you at the survey, before you spend anything.
From survey to switched on, in seven steps
Example timeline for a Holm Rack. Yours is set at the survey.
- Day 1
Step 1: Site survey
We visit, look at the room, the network and the work your people do, and leave you a written plan.
- Week 1
Step 2: Design
You get a fixed quote: which size, which models, which folders it will read, who can use it.
- Weeks 2 to 3
Step 3: Build and soak
We build the machine and run it flat out for a week in our workshop before it goes anywhere.
- Week 4
Step 4: Install day
We bring it in, rack it, connect it to your network and nothing else. Most installs take a morning.
- Week 4
Step 5: Connect your documents
It indexes the folders you chose and inherits their permissions. Your files stay where they are.
- Week 5
Step 6: Train the team
Two short sessions: what to ask it, how to check an answer, what not to rely on it for.
- From week 5
Step 7: Handover and care
You hold the keys. We monitor the hardware, update models on your say-so, and replace parts that fail.
A cloud assistant is billed per person, every month. Holm is one purchase and a care plan. Move the slider to your headcount.
Between $10 and $120. Business plans are often $25 to $60.
Subscription, 3 years
$86,400
Holm Rack, 3 years
$69,360
At 60 seats the machine has paid for itself by month 26. After that the only running cost is the care plan.
Example figures: Holm Rack $42,000 installed, care plan $760 a month. Your quote follows the survey.

No. The model, the index of your documents and every question and answer stay on the machine. It has no route to the internet. If you want remote monitoring, it sends hardware health only (temperatures, disk state) and you can read exactly what before you turn it on.
