Software you own,
built around how your business operates.
We've already built the difficult stuff.
Tell us how your business operates, and we build you a system that fits exactly — assembled from proven, working parts, so you're not paying to build what's been built a thousand times. We set it up for you on hosting in your own name and keep it maintained*, but everything is yours — the account, the code and the data.
* We guide you through two quick, free signups (your code and hosting accounts, both in your name); your hosting provider bills you directly at their own rates. Ongoing maintenance is optional, and you can remove us at any time without losing a thing.
$299, one time. AI assembles proven Constellation modules into your first working app, tailored to how you run — days, not months. You never touch a line of code.
The code is fully yours: standard Laravel, exportable, no proprietary format, no lock-in. Download and self-host it whenever you want.
Optional, from $149/month, on your own hosting account (you pay the provider directly, we never mark up the infrastructure). We centrally manage the Constellation modules your app is built from and push updates to your server — security patches, dependency and framework upgrades. Shared modules mean a fix rolls out to everyone at once, so it stays affordable. Custom work is quoted separately. Or pay as you go, priced case-by-case. How maintenance works.
The hosting account is yours, so we're a caretaker you've handed a key to — not a landlord holding your app hostage. Because we built it, we already know the codebase, so maintenance is faster and safer. Revoke access and take it in-house any time.
Bespoke used to mean six months and a big invoice. Two things changed.
Owning your software was always the better deal — it just cost too much to build and too much to maintain. That's the part that's gone.
The building blocks are already built.
Bookings, memberships, invoicing, customer email, sign-in, surveys, audit trails — dozens of proven, working modules, live today and tested. Your system is assembled from them and configured to your rules, not built from a blank page. That's why it doesn't cost six months.
Browse the catalogueAI does the tailoring — and the upkeep.
The expensive part of owning software was never the first build — it was every change after. Here, when something needs to change — a new price, a different rule, a report you wish you had — you describe it in plain English and the AI makes the change. No support tickets, no vendor roadmap, no developer day-rates.
So the system is yours. Actually yours.
It exports as standard code you can take anywhere, and your customer data lives in your database — not a vendor's. No per-user pricing, no bill that grows with your success, no losing everything if you walk away. The subscription you replace pays for the system that replaced it.
The same blocks, shaped into very different businesses.
These aren't mock-ups — each one is a complete, working system you can read about in full.
One park, one system: bookings to housekeeping to the invoice.
Pitch bookings with seasons and changeover days. Arrivals and departures boards driven straight from those bookings, with cleans raised automatically at checkout. Shop extras billed onto the guest's invoice in one action. Seasonal pitch licences with instalment plans and overdue chasing. Every piece reads the others — no exports, no re-keying.
Memberships, the door, and the chase-up list.
Your tiers and prices, front-desk check-in that refuses lapsed members with the reason on screen, renewals ready for a mail merge, court bookings and invoicing.
The till, the rota, and a cellar that counts itself.
Your menu at your prices, tabs and takings, the week's shifts costed in wages — and every sale drawn straight off the stock count, so the till and the storeroom always agree.
Rent, repairs, and compliance dates that chase themselves.
Rent and arrears by property, repairs from report to invoice, and gas-safety and EPC dates flagged before they lapse — one system across the whole portfolio.
Deadlines, fees, and the work that flows between them.
VAT quarters, year-ends and payroll tracked per client from due to done — each job's fee landing on the client's statement the moment it's filed.
Appointments, recalls, and fees in one diary.
Rooms and practitioners booked without clashes, recalls scheduled the moment an appointment is, and each visit's fee on the invoice — no wall chart, no lost charges.
A real tender, answered line by line.
A council's actual specification for facility bookings, invoicing and memberships — met with working software instead of a proposal document.
An assistant that answers from your content.
Ask it anything about your business and it answers from your own documents, citing its sources — on your own AI keys, with your data staying yours.
Paid plans on your own Stripe account.
A pricing page, checkout and recurring revenue — the money flows through your Stripe account, not a middleman's platform fee.
Don't see your business? Describe it.
Tell us what you need in plain English. If we've got the modules, we build it — the same app you own, on hosting in your own name.
Start with a conversation, not a spec document.
Tell us how you operate, and we build you a system that fits exactly — assembled from proven parts, tested, and handed over as code you own. The aim is simple: a system that fits better than what you rent today, for less than you're paying for it.
Pick your business and answer a few questions — about ten minutes, in plain English. Then it's a one-off $299 to build it — no subscription required, no lock-in: your system assembled, tested, and set up for you on hosting in your own name, ready to log in and use. A complete, working application that's yours to run, change forever, and take anywhere. Want it looked after? We can host and maintain it on your own account from $149/month — pushing module security patches and framework updates to your server — or pay as you go, priced case-by-case. Optional, and you can take it in-house any time.
