Free working prototype in five days
Your operation runs on a spreadsheet. See it as real software in five days.
Free working prototype, built from your actual process. If it’s not obviously better than what you have now, you owe us nothing.

The problem
You know exactly which file we mean
The one that runs dispatch. Or pricing. Or the production schedule. Forty tabs, a decade of formulas, and one person who actually understands it.
It works — until someone’s out sick, or a formula breaks silently, or a new hire takes four months to become useful. You’ve thought about replacing it. Every quote came back at six figures and nine months, so you didn’t.
Proof
Here’s one running on a shop floor right now
We built a production system for a furniture manufacturer — planning, inventory, and floor tracking. It replaced a spreadsheet, a whiteboard, a stack of paper travellers, and one rep who knew which orders were actually urgent.
In the first month, on-time delivery went from around 60% to 87%. Throughput rose 28%. Not because anyone worked faster — because the guessing stopped.

How it works
Five days, not nine months
No discovery phase. No requirements document. No invoice.
- 1
Forty minutes on a call
You walk us through the process. We ask about the parts that annoy you. No discovery phase, no requirements document, no invoice.
- 2
Five days
We build a working version. Not a mockup — real software, running in a browser, built from your process and what you said matters most.
- 3
You decide
Like it, we build the production version at a fixed price agreed upfront. Don’t like it, we shake hands and you keep the prototype.
The five days
- Day 1
Your data and the flow: what comes in, what goes out, who does what.
- Days 2–3
The main screens, on your real data.
- Day 4
The reports, and the awkward cases you told us about.
- Day 5
You get the link, and we walk you through it on a call.
Guarantees
What you risk is forty minutes.
- We’ll sign an NDA before the first call, if you’d like.
A working prototype in five days, free
Built on your real process. If it isn’t clearly better than what you have now, you owe us nothing.
A fixed price before you sign
You see the number before any contract, and it doesn’t move halfway through.
The code is yours
Repository, documentation, deployment. No licences, no per-seat fees.
Warranty included
Anything that’s on us gets fixed at our cost for the whole warranty period.
Ownership
No licences. No seats. No renewal email in eighteen months.
When the build is done, the code is yours. The repository, the documentation, the deployment. If you want to hire someone to extend it in three years, you can. If you want to bring it in-house tomorrow, you can.
Your only ongoing cost is hosting, which for most of what we build runs about what you’d pay for a couple of phone lines.
What we build
Internal tools, mostly
Production planning and floor tracking. Dispatch and scheduling boards. Quoting and pricing tools. Inventory allocation. Order intake from PDFs and email. Commission calculators. Customer portals.
Spreadsheets are usually where it starts, but the same applies to anything held together by a shared drive and institutional memory — manual processes, tools your ERP doesn’t cover, systems that don’t talk to each other.
We don’t build consumer apps, marketplaces, or anything with a mobile app store listing. We build the thing your team opens at 7am.

How we build
AI builds fast. Senior engineers sign off on everything.
We use AI to prototype and move quickly: the first working version exists in days, not months. Nothing ships on that alone. Experienced engineers review, test and validate every line before it reaches you.
The speed comes from the tooling. The quality comes from people with ten-plus years of production systems behind them, who know what breaks in month six and build so it doesn’t.
No junior developers learning on your project. No code we haven’t read ourselves.

Technologies
What we build with
We pick the stack that fits the job and the systems you already run. Most of what we build is React and TypeScript on the front, with the back end and integrations shaped by what you have in place.
- React
- TypeScript
- JavaScript
- Node
- Salesforce
- Shopify
- Postgres
- Python
- Azure
Why it’s free
The obvious question
Five days of our time is a cheaper way to earn a contract than three months of proposals.
Because explaining that we’re fast is worthless, and showing you is easy. Five days of our time is a cheaper way to earn a contract than three months of proposals and reference calls.
We’re selective about who gets one — we take on a handful at a time, and we only start when we’re confident there’s a real project on the other side. If we don’t think we can build something you’ll want, we’ll say so on the first call rather than waste a week of both our time.
FAQ
How can you build in five days what agencies quote nine months for?
Because we use AI-assisted development for the parts that are mechanical, and because we’re building one tool rather than a platform. The nine-month quote usually includes six months of process. We skip that and show you working software instead.
What happens when it breaks?
Every build includes a warranty period where we fix anything that’s our fault, free. After that you can buy a support retainer or take it in-house — the code is yours either way, and we document it so someone else can pick it up.
What does the full build cost?
It depends how much of your process it covers. Simple tools start around $1,000 to $2,000. Bigger builds go up from there. Either way the price is fixed and agreed before we start — you’ll have a number before you commit to anything, and the prototype comes first regardless.
Who actually works on my project?
A small team pulled from our senior bench, matched to what the work needs, with two senior delivery managers running it. You’ll know who they are before we start.
Where are you based?
Europe, working US hours.
Do we have to replace the spreadsheet entirely?
No. A lot of what we build reads from or writes back to what you already have. The goal is to remove the fragile part, not to make your team relearn everything.
Booking
Forty minutes, and you’ll know whether this is worth your time.
Bring the file. We’ll tell you on the call whether we can build it.
What happens on the call
- 1
You show us the file or the process. Screen share is fine.
- 2
We tell you straight whether we can build it in five days, and what it would cost after.
- 3
If yes, we agree what the prototype must do. If no, you have lost forty minutes.
No slide deck, no pitch. An engineer, your process.
