Custom software, built for NZ businesses

Software built around your business

Off-the-shelf tools force your business to work the way they were designed. Custom software does the opposite — it's shaped around the way you already work, solving the specific problem no product on the market was built for.

When the software doesn't fit

Most businesses run on a patchwork of tools that almost fit. You bend your process around the software's assumptions, paper over the gaps with spreadsheets, and pay a growing stack of monthly subscriptions for features you don't use — while the one thing you actually need it to do stays just out of reach.

The reason is simple: off-the-shelf software is built for the average of thousands of businesses. It was never built for yours — your workflow, your data, your customers, the specific bottleneck that costs you time and money every week.

For a long time, building something custom meant a six-figure budget and a year of development. That's no longer true. With modern AI-assisted development, a focused, well-scoped tool can be built quickly and at a fraction of the old cost — which puts custom software within reach of businesses it never used to be an option for.

What custom software gives you

Built for your exact problem

Not a generic tool you adapt to. Software designed around your real workflow — so it removes the friction instead of adding a new layer of it.

A lasting business asset

It's yours. A tool you own outright that makes your operations sharper and helps you deliver better for your customers — value that compounds long after it's built.

Priced as an asset, not a seat count

Built for you as a one-off, fixed-price asset — not rented per user, and nothing you need held back behind a higher pricing tier.

Fast, and surprisingly affordable

AI-assisted development means a well-scoped build ships in weeks, not months — at a cost that makes sense for small and mid-sized NZ businesses.

Something your competitors can't buy

Anyone can subscribe to the same SaaS you can. A tool built around how your business uniquely works is an advantage that isn't available off the shelf.

You stay in the driver's seat

Built in your accounts and handed over with you in control — documented, and yours to maintain or extend as your business changes.

This is the work I love most

Building software that solves a real, specific problem for a real business is my favourite kind of work — and the kind I'm best at. There's nothing quite like handing over a tool that changes how someone's business runs.

I work directly with the people who'll actually use what I build. No account managers, no offshore hand-off — the person scoping your problem is the person writing the code.

How it works

1

Free discovery call (1 hour)

We start with a proper conversation — no cost, no obligation. You walk me through the problem, and together we work out whether custom software is the right answer and whether the idea is feasible and sensible. If it isn't, I'll tell you. You leave with clarity either way.

2

Scope & fixed-price proposal

If it makes sense to proceed, I map exactly what the tool needs to do and come back with a clear scope, timeline, and a fixed price. No open-ended hourly billing — you know the number before anything is built.

3

Build — MVP first

I get a working version in front of you as fast as possible, so you can react to something real rather than a spec. Your feedback shapes the final build, so what you end up with is exactly what you need.

4

Handover — you own it

The finished tool is delivered in your accounts, documented, and handed over with you in control. It becomes a lasting asset your business owns.

Not sure yet whether your idea is a fit? That's exactly what the free discovery call is for.

Founder & AI Solutions Builder

I'm Joe Sutheran, founder of Growth Medium AI in Wellington. I've spent two years building production AI systems, and nearly a decade before that working inside NZ service businesses.

That combination is what makes custom software work: I can walk into a business, quickly understand how it actually operates, spot where the drag is — and then build the thing that fixes it.

Every build is done with you, not to you. You're close to it the whole way, and you own what we make.

Tell me what you'd build

Got a problem that no software seems to solve? I'd like to hear about it. The discovery call is free — one hour, no pressure — and by the end we'll both know whether it's worth building.
