Sovereign AI deployment for small firms

Private AI that stays inside your company.

NorthHaven AI installs open-source AI models and a private knowledge base on your own server — in your office or your private cloud. Your staff can chat with your documents, draft faster, and find answers in seconds. Your client files never leave your control.

No cloud uploadsNothing is sent to ChatGPT or any outside AI

How it stays private

Everything runs inside one boundary: your network.

Data stays in-house
▣ Your office · Your server · Your network
Your documentsCases, charts, contracts, tax files, SOPs
Private knowledge baseSearchable, permission-controlled
Local AI model — running on your hardwareAnswers, summaries, and drafts generated on-site. Works even if the internet goes down.
Your teamAsk in plain English. Every answer cites the file it came from.
What does not happen

Your files are not uploaded, not used to train anyone else's model, and not visible to an outside vendor.

Open-source models Role-based access Audit log No per-seat cloud AI bill
The problem with cloud AI at work

Your team is already pasting client work into AI. The question is where it goes.

Free and cloud AI tools are useful — until a client file, a medical note, or a tax return leaves your control. Compare the two ways to give your team AI:

☁ Cloud AI tools

Staff paste or upload work into an outside service.

  • ✕Data leaves your office. Prompts and files travel to a vendor's servers, under their terms.
  • ✕You can't fully control retention. Policies change; deletion and training-use rules are theirs, not yours.
  • ✕Hard to answer a client who asks. “Where did our file go?” deserves a better answer than a terms-of-service page.
  • ✕Costs grow per person, forever. Every new hire adds another monthly AI subscription.

NorthHaven private AI

The same kind of help — running on equipment you control.

  • ✓Data stays on your network. Documents and questions never leave your server.
  • ✓You set the rules. Who can see which folders, what gets logged, and when files are deleted.
  • ✓A clear answer for clients & auditors. “Our AI runs in-house. Your file never left this building.”
  • ✓One deployment, whole team. No per-seat AI subscription multiplying as you grow.
What we do

Three services. One goal: AI you control.

We handle the technical work end to end — hardware, models, setup, and training — so your team just opens it and starts asking questions.

01

Private AI deployment

We install and tune an open-source large language model on a server in your office (or your private cloud) and connect it for your team.

  • Hardware recommendation & setup — right-sized, not oversold
  • Model selection for your work: drafting, summarizing, Q&A
  • Secure login for staff, on your network only
02

Private knowledge base

Your documents become a searchable AI assistant. Ask a question, get an answer with the source file attached — no digging through folders.

  • Built from your files: PDFs, Word, scans, policies, templates
  • Every answer cites its source, so staff can verify in one click
  • Folder permissions mirror who can already see what
03

Workflow agents & training

Once the basics work, we automate the repetitive parts — intake summaries, first drafts, routine Q&A — and train your team to use them well.

  • Agent permissions: what each assistant can see and do, in writing
  • Hands-on training for your staff, in plain English
  • Ongoing support, updates, and model improvements
Who we help

Built for firms that handle other people's sensitive information

If your clients trust you with private files, “we pasted it into a cloud chatbot” is not a policy. These are the firms we deploy for first:

Law firms

Case files, contracts, and discovery stay privileged — and stay in-house.

  • Search years of case files in seconds, with citations
  • First drafts of letters, memos, and summaries from your templates
  • Intake summaries from consultation notes

Dental & medical practices

Patient information never leaves your practice network.

  • Front-desk answers from your own policies & FAQs
  • Staff handbook & SOP search — no more asking around
  • Draft referral letters and patient instructions for review

Accounting & tax firms

Client financials are the last thing that should sit on someone else's server.

  • Find the answer in prior returns, workpapers & IRS guidance you keep
  • Summarize long client document bundles
  • Draft client emails and checklists from your templates

Also a fit for insurance agencies, wealth advisors, and any New Jersey business that handles confidential client records.

Try the idea — a private knowledge base, in miniature

This is an illustration with sample content, not your data. Pick a question a team like yours asks every week, and see the kind of sourced answer your private system gives.

In a real deployment, answers come only from your files, on your server — and staff can open the cited source to verify before they act.

How it works

Start small. Prove it works. Then expand.

No big-bang project and no leap of faith. You validate the system on your real work first, before you commit to a full deployment.

1

Assess

We visit (or video-call), look at your documents, network, and hardware, and agree on exactly what the AI should — and should not — do.

Discovery call · Free
2

Pilot — 1 week

We stand up a working pilot on a small, agreed set of documents. Your team uses it on real tasks and tells us honestly if it earns its keep.

Fixed scope
3

Deploy

Full rollout on your server: all agreed folders, staff logins, permissions, and audit logging — tested with you before go-live.

4

Train & support

Hands-on training for your team, a plain-English admin guide, and ongoing support as models and your needs improve.

Data sovereignty

“Sovereign AI” simply means: you are in charge of your AI

Governments and large companies now use this term for AI they control themselves. The same idea, sized for a small firm, is what we install:

  • ✓Your data stays yours — stored on your equipment, never used to train outside models
  • ✓Your rules apply — access by role, audit logs, and retention you decide
  • ✓Your AI keeps working — even if a vendor changes prices, terms, or shuts a product down
  • ✓Your costs stay predictable — open-source models, no per-message cloud fees

“Our AI runs in this building, on our server, on our files. A client's information has never left this office.”

— The sentence your firm should be able to say to any client who asks. That's the deployment we build.
A note on compliance: A private, in-house deployment helps you keep sensitive data under your own controls. It does not by itself make any firm “compliant” — your existing policies, training, and professional obligations still apply, and we'll configure access and logging to support them.
Questions owners ask us

FAQ

Does our data ever leave our office?

No — that's the point of the deployment. The model and your knowledge base run on your server, and questions and documents stay on your network. If you prefer a private cloud you control instead of a physical server, we can deploy there with the same principle: your account, your keys, your rules.

Do we need fast internet — or any internet — for it to work?

Once installed, the system runs locally and can work without the internet. Internet is only needed for setup, updates, and any outside tools you explicitly approve.

What AI models do you use?

Leading open-source models, chosen for your hardware and your work — for example, strong general models for drafting and Q&A, and specialized options where they help. Because the models are open-source, you're never locked to one vendor, and upgrades don't require a new subscription.

What hardware do we need? Do we have to buy a big server?

Many small firms start on a single workstation-class machine with a capable graphics card. In the assessment we check what you already have, recommend the minimum that will feel fast, and tell you plainly if you don't need to buy anything yet.

How much does it cost?

It depends on your hardware and scope, so we quote a fixed price after the free assessment — starting with the fixed-scope 1-week pilot, so you can judge the value on real work before committing to a full deployment. There is no per-seat cloud AI subscription on top.

What if our team isn't technical?

That's normal, and it's who we build for. Staff use a simple chat screen in plain English. We train your team in person, leave a short admin guide, and stay available for support.
