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. Everything is yours: the code, the data, the hosting.
You own the code — standard, modular Laravel that follows Laravel conventions — so your developer, or a Stellify partner, can host and maintain it. When our modules improve, pull the update in Studio and sync it to your GitHub repository, ready to deploy — keeping a system current is included in Studio plans.
Systems from £995, quoted instantly and itemised line by line — you see exactly what you're getting before you pay, and preview it before it goes live. 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. Keeping it current with our improvements runs through Stellify Studio, but the system is yours whether you use it or not. Download and self-host it whenever you want.
Your system is built on Laravel — the world's most popular PHP framework, used by companies like Currys, MKM, Apple, Nike, NASA and Pfizer.
The building blocks behind your system are improved and tested centrally. Those improvements reach your system through your developer or partner, so it keeps getting better after you buy it. How hosting & support works.
Your own developer, or a Stellify partner, hosts and looks after it — on your infrastructure, on terms you agree with them. No landlord holding your app hostage, us included: change who runs it whenever you like.
What it costs to run
Your system is yours, so there's no licence fee. These are the running costs to plan for:
Paid directly to your hosting provider, typically a modest monthly amount for a small business system.
Your developer or Stellify partner's care plan, on terms you agree with them.
Improvements to the building blocks reach your system through Stellify Studio, which your developer or partner uses.
Automated workflows use an AI service, paid by usage.
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 inside the system does real work.
The AI in your system runs business tasks — chasing what's owed, confirming bookings, sending the right email at the right moment — with confirmation required on anything financial or irreversible, and a full audit trail. When the system itself needs changing, your developer or Stellify partner makes the change in the Studio or the code.
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.
Every platform added an AI box that answers questions. We build systems where the AI does the work.
A platform serving thousands of businesses can only safely ship AI that looks things up. Software you own has one business in it: yours — so the AI inside it can be trusted with real work.
It works without being asked.
Your system is on at three in the morning whether anyone's watching or not — so work runs on a schedule or fires off the back of an event, and stops for a person at the steps that matter. Here's a Monday running itself:
It acts as the person who asked. The receptionist can release a booking; only the duty manager can cancel a Direct Debit.
Every action has a name on it. “By Sarah, at 14:06, because the member called” — in your own audit trail.
The steps never improvise. The AI recognises the task and fills in the details; the steps are code, identical on every run.
It's in the screen already open. Not another tool to install — one more thing the software they already use can do.
And it knows where to stop. Anything irreversible — moving money, cancelling an agreement, deleting records — stops and asks a person first. Everything else runs, and every action is recorded: what ran, when, for whom, and who authorised it.
Why AI belongs inside your softwareWorking systems for businesses like yours.
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.
The fleet, the diary, and off-hire that bills itself.
Every machine's whereabouts, bookings with deposits and damage waivers, hire periods that turn into invoices automatically — and overdue kit that charges until it's back in the yard.
Works orders, stock and quality — off the spreadsheets.
Every job's stage from order to despatch, material drawn down as it's used, certificates filed against the job with expiry dates tracked — and the invoice raised when it ships.
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 outright, run by your developer or a partner.
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 — and for many businesses, the quote comes in under a year of their current subscriptions.
Pick your business and answer a few questions — about ten minutes, in plain English. You get an instant, itemised quote — systems from £995 — spelling out exactly what your system will do, line by line, before you pay anything. Confirm it's right and pay; we build it and you preview the finished system against that exact list. If the system doesn't match the requirements you accepted, we fix it or refund you in full. Then it's yours: a complete, working application exported as standard Laravel, hosted and looked after by your own developer or a Stellify partner, yours to run, change forever, and take anywhere. And it keeps improving — when our modules improve, pull the update in Studio and sync it to your GitHub repository, ready to deploy. Keeping a system current is included in Studio plans.
