The spreadsheet that runs your business? Retire it.
We turn the spreadsheets and the £300-a-month subscription stack into one custom app — built around how your business actually works. Fixed price, built in fortnights — a Spreadsheet Rescue needs just one — and you own it outright. No per-seat fees. No price rises. Ever.
One project at a time. Every fortnight ends with working software. Live, not a progress report.
What happens in a build fortnight
Tap a day to see the work ↓The clock starts on access
Day 1 is the day we have your content, data and logins — not the day the invoice is paid. Our Day-1 checklist makes getting there quick.
Weekends are yours
Days 6 and 7 are review windows, not build days. You test, we rest, and your change list lands Monday morning — no meetings required.
Every fortnight ships
Small builds take one fortnight. Big ones run as back-to-back fortnights — and every single one ends with working software live, not a progress report.
The problem
Your business runs on borrowed time and rented software.
Nearly every small business we meet runs on one of two things — and usually both. A spreadsheet held together by hope, and a stack of subscriptions that does 10% of what you pay for.
Exhibit AThe Spreadsheet
- One person understands it — and they're on holiday
- Breaks silently; you find out when a customer does
- No audit trail, no permissions, no "who changed this?"
- Unusable on a phone, on site, or in a van
- One sort-gone-wrong from disaster
Exhibit BThe Subscription Stack
- £50–£500 a month, forever, for features you don't use
- Per-seat pricing that punishes you for growing
- Price rises every renewal — and you can't leave
- Your data lives in their system, not yours
- Built for everyone, so it fits no one
The third option: software built around how you work. Pay once. Own it forever.
One senior builder using modern AI tooling to deliver in a fortnight what custom software houses quote months and five figures for — with every decision reviewed by a human who's spent years replacing spreadsheets inside real businesses.
Fixed prices, published here
The price on the site is the price on the invoice.
Three packages, each with a published day-count. No quotes, no "POA", no creeping scope. If your project doesn't fit a package, we'll tell you on the kickoff call — before you've paid a penny.

Care Plan — hosting, backups, and a builder on call
Secure hosting, monitoring, backups, and up to 2 hours of changes every month. Cancel any time — and because you own everything, the app stays yours if you do. Try doing that with your current subscriptions.
£99/month
Do the maths on your subscriptions.
Drag to what you currently spend per month on the tools a custom build would replace — CRMs, job schedulers, form builders, booking systems, the lot.
Based on the £5,950 Subscription Killer build + £99/mo Care Plan, vs. your current spend continuing. Excludes the inevitable SaaS price rises — so the real number is better.
How we build
Yes, we use AI. Here's exactly how.
We're not hiding it — it's the whole reason custom software now costs thousands, not tens of thousands. AI tooling does the heavy lifting; years of building real business systems does the judging. You get the speed without the slop.
AI does the volume
Drafting code, building screens, writing tests, migrating data. The repetitive 80% that used to take a dev team months.
A human does the judgement
Data design, security, permissions, what your team will actually use on a wet Tuesday. Every line reviewed before you see it.
You get the savings
Faster builds mean software-house quality at a fraction of the price — that's the deal. We don't charge 2019 prices for 2026 speed.

Who you're dealing with
Leesy is one person. That's the point.
Hi — I'm Leesy.
By day I'm the technology director of a UK staffing and events group, where I've spent years doing exactly what Leesy Studio does: replacing the spreadsheets, duct tape and subscription sprawl of a real, messy, fast-moving business with systems hundreds of people rely on every week.
Leesy Studio is that experience, productised. When you book a build, you get me — not a junior, not an account manager, not a ticket queue. One builder, your project, a fortnight at a time. And because I run technology for a living, I build like someone who has to live with the consequences: secure, documented, and handed over properly.
Ethos
Five things we won't budge on.
Shipped beats perfect
Every project has a go-live date before it starts. An app your team is using beats a requirements document every single time.
One builder, full attention
No account managers, no handoffs, no "I'll check with the dev team." You talk directly to the person building your system — and we take one project at a time.
AI is the leverage, not the product
We use AI to move at ten times the speed. We use experience to make sure it's right. You should never be able to tell which is which.
Own, don't rent
Your code, your database, your logins. No per-seat fees, no renewal rises, no hostage data. If we vanished tomorrow, your app wouldn't. That's the test every decision has to pass.
Honest scope, honest price
Prices are published on this page. If something will cost more, you'll know before we start — never after.
