Software built for real users.Not just the demo.

Starting from an idea, a prototype, or a product that’s outgrown itself, we get it to production and keep it there.

  • One fixed price.
  • Senior engineers.
  • You talk to the person writing the code.

The problem

Building a demo got easy.Building a product didn’t.

AI tools can put an idea on screen in a weekend. That’s real progress, and plenty of good products start that way. But a demo isn’t a product. Real users bring real load, real data, payments, security, edge cases, and systems that don’t cooperate. That’s where most of the work is, and where most projects stall.

Diagram: a demo dashboard running on localhost with 12 users sits on top. Beneath it is the work real users bring: real load such as 40,000 requests a minute at peak, millions of messy records, payments with refunds and disputes, security with roles and audit logs, edge cases like timeouts and retries, and legacy systems with rate limits. That is where most of the work is.

The usual agency doesn’t solve it either. They bill by the hour, so delays pay them. You meet a senior engineer at the pitch, then get handed to juniors you never interviewed.

What’s scarce now isn’t code. It’s senior judgement about what to build, and the experience to make it hold up once people depend on it. That’s what we sell.

How we work

We sell outcomes, not time.

Every engagement is a fixed result at a fixed price. We don’t bill hours, rent you people, or pad a timesheet.

  • One price, agreed before we start.

    We scope it, quote it, and you approve it. If it takes us longer than we thought, that’s our problem, not your invoice.

    1. Scope
    2. Quote
    3. You approve
  • Senior only.

    No juniors learning on your budget.

  • No middlemen.

    The engineer who scopes your project is the engineer who builds it, start to finish.

  • A few projects at a time.

    On purpose, so each one gets real attention.

What we don’t do

  • Staff augmentation
  • Hourly contracts
  • Tenders
  • Renting engineers by the seat

If you need bodies, we’re the wrong call, and we’ll tell you on the first one.

One team, one point of accountability

Led from Melbourne. One senior engineer owns your project end to end. The person you scope with is the person who builds it. No salesperson who disappears after signing, no account manager passing messages. You always know who is answerable for the result.

We’re a small, deliberately distributed team, and the people who start your project finish it. No rotating staff, no hand-offs, no ticket queues. Our working hours span your afternoon and evening, so work gets reviewed and directed every day, not read back the next morning.

With the usual agency, you go through a salesperson and an account manager before reaching juniors. With Gavi, you work directly with the engineer who builds it.

One team, one price, one person answerable for the outcome.

Services

Wherever you’re starting

  • From an idea.

    You know what you want to build, and you need the whole thing done properly. Web, mobile, APIs, and the infrastructure underneath, live and ready for real users.

  • From a prototype.

    You built something with AI tools or a freelancer, and it proves the idea. Good, you’re ahead. We review what you have, keep what works, and build the rest properly: authentication, security, payments, scale, and code your team can maintain. If it’s faster to start fresh, we’ll say so.

  • From a product that’s creaking.

    It’s live, people use it, and it’s struggling to keep up. Legacy modernisation, cloud costs, reliability and incidents, real-time data, and getting AI tooling into your engineering team properly.

  • AI, built to survive production.

    Agents and AI features wired into real systems, with the data handling, security, and controls that keep them working after launch. Most AI projects that fail, fail in production. Ours are built by people who’ve run regulated systems at scale.

Process

How a project runs

  1. Call, 30 minutes.

    You describe the problem. We tell you honestly whether we’re the right people. No deck.

  2. Blueprint.

    We work out what actually needs building and give you a technical plan, an architecture, and a fixed price for the build.

  3. Build.

    Fixed price, paid at milestones. You see working software at every one.

  4. Live.

    We ship it, hand over the repos, cloud accounts, and keys, and stay on as long as you want us.

What it costs

Compare us to a hire, not an agency

A senior hire

Around $200,000 a year

once you add super and on-costs.

  • Finding one takes three months.
  • You won’t know if you picked right until they’ve been there for six.
  • One person.

Gavi

Your product live before you’d finish interviewing.

For less than that hire costs you in a single year.

  • A full team, not one person.
  • One price, agreed before we start.
  • Senior only.

Builds

Every product is different, and every prototype is at a different stage. So we don’t guess. Your Blueprint ends with one fixed number. That number doesn’t move unless you change what you’re asking for.

If your prototype is faster to rebuild than to build on, we’ll tell you, even if it means a smaller job for us.

A fixed quote from your Blueprint

Cloud cost review

Two weeks inside your cloud setup. You get a list of specific savings and how to make them. If we don’t find at least three times our fee in first-year savings, you don’t pay.

$6,000, or free

All prices in AUD, ex-GST. Guarantees are subject to our terms.

How a fixed price stays fixed

Plenty of “fixed price” shops pad the quote, then send change requests to make up the rest. Here’s how ours works, in writing, before you sign:

  • The scope is written down.

    Including what’s excluded.

  • Changes are your choice.

    If you want something new, we quote it first. You approve it or you don’t. Nothing starts until you say yes.

  • You pay at milestones, not up front.

    Each payment comes after you’ve seen working software.

  • If we underestimated, we wear it.

    Our mistake is never your invoice.

You will never get a bill you didn’t approve.

FAQ

Why isn’t the team on the site?

We’re small and deliberately low-profile. You’ll meet the engineer who’d build your project on the first call, before you commit to anything.

Where is the team based?

Led from Melbourne, with part of the team in India. We’ll be straight about that, because it’s nothing like what “offshore” usually means. Offshore normally means you brief an account manager, the work goes into a queue, and you get whoever’s free that week. Here it’s the same senior engineers from first call to launch, led and owned from Melbourne, with one person accountable for the outcome at a price that doesn’t move. The time zones help too: the team’s day overlaps your afternoon and evening, so your project moves forward daily instead of stalling overnight.

Why do you charge for the Blueprint when agencies quote for free?

Because a free quote is a sales document. It’s written to win the job, not to be right. The Blueprint is real engineering work: it’s what makes a fixed price possible, and it’s useful to you whether or not we build it. If it isn’t, you get your money back.

What if it takes longer than you quoted?

That’s our risk. The price only moves if the scope moves, and scope changes are quoted and approved before any work starts.

Can’t AI tools build this for free now?

They’ll get you a demo. They won’t get you a product. The gap between “it works on my screen” and “it’s safe, stable, and ready for real users” is most of the actual work: auth, security, edge cases, real data, integrations that don’t cooperate. That gap is what we do. It’s also why a lot of our projects start from a prototype someone built with AI.

Do you work alongside our team?

On projects, yes. We don’t rent out engineers to sit inside your team. That’s a different business and we’re not in it.

Who owns the code?

You do, from the first commit. Your repos, your cloud accounts, your keys.

What if we’re not sure what we need yet?

That’s what the Blueprint is for. Worst case, you walk away with a technical plan you can hand to anyone, or your money back.

Something else? Ask the engineer directly on a call.

Talk to the engineer,not a salesperson.

Thirty minutes, no pitch. If we’re not the right fit, we’ll tell you and point you somewhere better.
