The next phase of AI as a service

You already see what AI can do
for your business.

Now take it to the next level — AI designed, structured and owned in-house, built around the way your business actually works.

Built so you can show anyone — your board, your accountant, your lawyer — exactly how it works.

The answer

The next step is
owning one.

A specialised agent, shaped to your niche. Open-source models, your data, your hardware or private cloud — and you own what comes out of it.

01 — the shift
Where most businesses are now

Generic AI, rented by the seat

—Every prompt starts from zero. It doesn’t know your clients, files or process.
—Your documents leave the building to be processed.
—Per-seat fees climb with every hire; the vendor owns the roadmap.
—Helpful. Impressive, even. But not yours.
Where the advantage is

In-house AI design and structure

+Built and wired into your processes, templates and language.
+Open-source models running on infrastructure you control.
+One build cost, no per-seat tax. Add the whole team.
+An asset on your balance sheet, not a subscription on your card.
+First workflow live in weeks, not next financial year.
02 — side by side, in your niche

Pick a trade. See what its agent takes off the desk.

Same idea, different shape. The agent learns one business deeply instead of all of them shallowly.

03 — how it works

Four steps from conversation to a working colleague.

01

Map the week

A working session on where the hours actually go. We leave with a ranked list of workflows, an honest read on which are worth automating first, and an agreement up front on what the agent will never decide on its own.

Free 15-min call, then a half-day
02

Design the agent

Scope, data sources, tools and guardrails. What it can see and what it can act on — written down before anything is built.

Week 1
03

Build in-house

Deployed on your own infrastructure, connected to your systems, built on your documents and evaluated against real cases from your business. Decision logging and human sign-off are built in, not bolted on.

Weeks 2–6
04

Hand over and grow

You get the Handover Pack: a model card, a data provenance sheet, the decision-log schema, the never-list as built into the software, and a plain-English operating guide. Your team runs it from there — we watch its health and usage metrics, never your documents, tune it, and add the next workflow when you’re ready, or hand the keys over entirely.

Ongoing, your call
04 — where your data lives

All in-house. Nothing leaves unless you say so.

Where it physically runs is your call, driven by your IP and compliance needs. Whichever you pick, it connects securely to the software you already use, always behind a boundary you control.

Your system is yours alone. It is built on your data — your documents, your work, your examples — and nothing from your business ever improves another client’s system. At handover you get a data provenance sheet: what it was built on, from when, and what it wasn’t.

On your own hardware

Full sovereignty

A machine in your own office, sized to the firm. Best for regulated records and sensitive IP.

Data sits on your premises. Reachable only from your network, by people you already trust with the files.

Private rack, local data centre

In-jurisdiction

Dedicated hardware in a facility near you. Resilience and uptime without a hyperscaler’s shared tenancy.

Data stays in New Zealand, on hardware leased to you. Facility staff hold physical access; logical access is yours.

Dedicated cloud

Fastest to scale

Isolated cloud infrastructure when demand is spiky or teams are distributed. Same architecture, portable by design.

Data sits in a single-tenant instance in a region you pick. No shared model, no shared storage, keys held by you.

05 — how we build, and what you own

The shape of it, and exactly where the line sits.

How we build

Open models, your documents kept live, a person in front of anything that leaves

01We start from open-weight models with commercially permissive licences, chosen per engagement for the work in front of us — not one model for every client.
02We build the system around your business rather than wrapping a third-party API in a prompt: your tone, your document formats, the way your firm actually works. Where your output is distinctive enough to earn it, we adapt the model itself.
03Your live documents stay live. The system reads them as it answers rather than having them baked in, so when a template or a price changes it is current that day — and answers drawn from your documents point at the document they came from.
04Anything that commits you — a price, an invoice, an offer, advice — passes the human sign-off built in during the build (step 03 of How it works). Routine acknowledgements and scheduling don’t need you; commitments always do.
Yours, on final payment

What you own

—Your data, and every derivative of it
—Any model weights adapted for your business
—The deployed system and its source, to run and modify for your own business
—The decision log and all its history
Ours, reused for everyone

What we retain

—Our build framework, tooling and scripts
—Our method and internal templates
—Reusable components that aren’t specific to your business

If we part ways, the system keeps running and someone else can pick it up. That’s the point of building it this way.

06 — what it takes to run

Where it runs, and what it costs to keep running.

Two questions every owner asks once they’re past “does this work”. Here are the honest answers.

What it takes to own one

Sized by the size of your firm, not by a spec sheet

A small practice — 1 to 10 people.A single workstation-class GPU, or a high-memory Mac Studio, handles a fine-tuned 7–14B model comfortably for a handful of people at once. It sits in your office, runs on normal power, and there is no per-seat bill.
A mid-size firm — 10 to 50.A two-GPU server with 48–96GB of video memory runs a quantised 30–70B class model with room for several people at once. Rack it in your own comms room, or put it in a New Zealand data centre.
Don’t want the capex?A dedicated single-tenant instance in a private cloud gives you the same isolation without buying hardware.
And the power behind it.A box that answers all day is a standing load, and it is the line most quotes leave out. PowerNode builds solar and battery systems around second-life EV packs — the same argument as owning the model, applied to the electricity that runs it.
Indicative only — we size this properly during the audit, including power, cooling, backup and what happens if the box dies.
What it costs to keep renting one

What a cloud-only subscription commits you to

—Per-seat and per-token pricing scales with success. The better it works, the more you use it, and the more it costs.
—You don’t control the price. A vendor repricing mid-year hits your margin, not theirs.
—Models get deprecated. A workflow tuned to a model that’s retired has to be rebuilt.
—Your accumulated context and fine-tuning live inside someone else’s account.
—Egress and integration costs are rarely in the sticker price.
An owned system has a known, front-loaded cost and something left at the end of it. A subscription has neither.

08 — questions
Isn’t building our own AI a big, expensive project?

Smaller than most expect. Open-weight models are free to license and now run well on a single workstation-class machine. The cost is in the design and integration work — scoped as a fixed-price build, typically weeks rather than quarters, starting with one workflow that clearly hurts.

Do we need an internal AI team to run it?

No. We deliver it documented and monitored, and either support it on retainer or hand it over with training.

What if we outgrow it, or the models improve?

That’s the point of open weights. Models are swappable components; the value sits in the structure, data pipelines and evaluations around them. Upgrading the engine doesn’t mean rebuilding the car.

Is using AI going to get me in trouble with the Commerce Commission?

The short answer is that a business stays responsible for what its tools produce, and the rules read the same way whether a person or a system made the call. The exposure sits with tools that act on their own, or that pass data and signals between competitors. Everything we build recommends rather than decides, and keeps a log of who approved what — so if you are ever asked, you can show the answer rather than argue it. Further reading: the Commerce Commission. We build systems that are straightforward for your own lawyer to review; we don’t give legal advice.

What if my competitor uses the same AI vendor as me?

That is the real risk with shared, multi-tenant tools — one algorithm learning from several competitors at once, inside a vendor you both pay. We build one model per client, on your data only. Nothing from your business ever informs another client’s system.

Do I need my own hardware?

No — but you can, and plenty of firms should. What it takes, sized by the size of the firm, is set out in what it takes to run above, along with the case for owning rather than renting.

My industry isn’t on your list. Does that matter?

Not much. The list shows shapes we have already thought about, not the limit of what this works on. What decides it is whether your business runs on documents you own — files, correspondence, records, a history of how you do things — and whether the same questions get asked of them every week. If that is true, the method is the same and only the vocabulary changes. If your work is mostly serving customers over a counter, or it already lives in one tidy system that answers well enough, we will say so on the call rather than after the invoice.

Where should we start?

The free 15-minute call. We map your week, pick the one workflow with the best ratio of pain to complexity, and tell you honestly whether it’s worth building yet.

Next step

Fifteen minutes. One honest answer.

Tell us what your week looks like and we’ll tell you whether a specialised in-house agent is worth building — and roughly what it would cost. No deck, no obligation.
