See it free, then launch in a day

There's no spec document and no six-week agency timeline. You see a working product before you pay anything. AI agents do the building, and every action they take passes through an approval layer.

01 · SAY IT

One sentence

Write one line, like “a sourdough bakery in Newtown that takes pre-orders.” That's all we need to start.

02 · SEE IT · FREE

Private preview

Within 2 business days you get a private link to a working preview: pages, products and checkout, with simulated payments. You can click through all of it.

03 · BUILD IT · 1 DAY

The real thing

Like it? Approve the brief and pay the deposit. In one business day we turn the preview into your product, with your content, real payments and an admin area.

04 · SHIP IT

Live in Sydney

It goes live on Microsoft Azure in Sydney with HTTPS, daily backups and monitoring, on your own domain, ready to market.

Why trust a one-day build?

The speed comes from controls I've already proven across a portfolio of production apps that I run myself.

Case study · AI governance 20 apps, 1 approval layer

How I governed AI coding agents across 20 live apps. A guard intercepts every destructive command, holds it for human approval or asks the agent to justify it, and logs everything for audit. That's why agents can work fast without being trusted blindly.

Insight · Compliance 12 of 36

12 of the 36 GDPR obligations I track are touched by no ISO 27001 Annex A control. Certification isn't the same as privacy compliance, so every product built here starts with the privacy basics in place: notices, data export and erasure.

Benchmark · Buy vs build 44 min vs 2 m 42 s

I ran the same task on a local model on my own hardware and on a frontier cloud model. Local AI is private and has no per-token cost, but cloud is about 16× faster. I use each where it wins, and that's how a day turns out to be enough.

Live product My Work

Turn any job ad into a two-page CV and cover letter tailored to it. It's a public product with sign-in, PDF and Word export, and recruiter share links. Try it now.

Built from a sentence

These are real products running right now. Each one started as a single line.

Pricing

You pay once to have it built and then monthly to keep it running. All prices are in AUD and include GST, and you own the code.

Every build starts with a free preview. You pay only once you've seen it. The deposit is taken when you approve the build, never before. Founding offer: 50% off your first 3 months. Applies to Starter or Growth hosting when you buy a build before 31 December 2026, for the first 25 customers only. Conditions

If you go over your plan's limits two months in a row, we'll move you up a plan with 14 days' notice. Full details are in the terms.

Questions

Do I pay before I see anything?

No. You get a free, private preview first. It's a working version you can click through, with simulated payments. You pay the deposit only if you want it built. A preview stays up for 14 days.

Is it really one day?

For a focused product, like a store, booking site, directory or small SaaS, yes. If one sentence actually describes three products, we'll say so in the morning brief, before any building starts.

Is it a template?

No. The agent writes real application code for your idea, and it's committed to a repository you own.

Who checks the AI's work?

A person does, at every gate. A governance layer holds risky actions until someone approves them, and every step is logged.

Can I take it elsewhere?

Yes. Once the build is paid for, the code is yours. You can host it with us or anywhere else, and if you leave we'll hand over the code and a database export within 14 days.

What if the build isn't finished in a day?

We keep working on the next business day at no extra charge. If it's still not delivered within 5 business days and the delay is our fault, you can choose a full refund of the build fee instead.

What happens after the 3 discounted months?

Your plan moves to the normal monthly price, and we email you 14 days beforehand. You can cancel at any time, and the discount is never clawed back.
