The Problem

Sound familiar?

✕Quotes priced in WhatsApp threads that vanish
✕Jobs tracked across six spreadsheets that don't talk to each other
✕Customers chasing you for updates because there's nowhere to check
✕Evenings lost to admin a system should be doing for you

Off-the-shelf software almost fits. But your business isn't off-the-shelf, and that's why the workarounds never stop.

The Fix

One workflow. One app. Three weeks.

We take the messiest part of how you work: quoting, bookings, job tracking, client updates, and turn it into a clean, simple web app your team actually wants to use. No hourly billing. No scope drift. You see the price before we start.

For Trade Businesses

Already sitting on jobs you've lost?

Plumbers, electricians, heating engineers and roofers lose booked work two ways: old customers who've gone quiet, and calls that ring out while you're up a ladder or under a sink. We recover both, and we only take a cut of what actually books.

Attraction · Pay on results

Dead List Revival

We run a text and email campaign to the customers you haven't heard from in years, at our own cost. If nothing books, you pay nothing. If a job books and completes, we take 15%.

Continuity · £0 Setup · Capped at £397

Missed Call Machine

Your line forwards to us when you don't pick up. Every missed call gets answered and booked straight into your diary, and you get the job details by text, day or night. There's no setup fee and no subscription. You pay a set fee per booked job, based on your trade, and you'll never pay more than £397 a month, however many jobs we book. Quiet month, you only pay for what booked. Busy month, you hit the cap and every job after that is on us.

Both are pay-on-performance, so you only pay when a job books, and the Missed Call Machine never costs more than £397 a month. Available now for plumbers, heating engineers, electricians and roofers.

CompliancePack, an MCS compliance pack dashboard
Proof

We don't just build apps. We ship products.

CompliancePack turns MCS compliance documentation into a five-minute job instead of a two-hour one. Renewable energy installers who used to lose whole afternoons to paperwork now get every job audit-ready before they've left the driveway. Stripe billing, e-signing, automated emails, all built in. Designed, built and launched by FeatherkiteStudio in weeks, not months.

How We Build

Built properly. Secure by default.

Anyone can spin up an app now. Building one that keeps your customers' data safe is a different discipline, and it is the one we take seriously.

✓

Your data stays yours

Every account sees only its own data, enforced at the database level rather than hidden in the interface. One customer can never reach another's information.

✓

Encrypted and backed up

Your app runs on enterprise-grade infrastructure, encrypted in transit and at rest, with automated daily backups and point-in-time recovery.

✓

Secrets stay secret

API keys and credentials are never written into the code or exposed to the browser, so there is nothing sensitive for anyone to find.

✓

Locked-down access

Two-factor authentication on every account behind your app, domains transfer-locked against hijacking, and access granted on a least-privilege basis.

✓

Reviewed before launch

Every app passes a documented security review before it goes live, against a checklist refined on our own production software.

✓

Kept current

We patch dependencies, act on vulnerabilities promptly, and re-run our security checks after every release. Security is never a one-off.

Featherkite is ICO-registered and GDPR-compliant. Every app is hosted, maintained and secured by the same team that builds it, with no hand-off to a third party who has never seen your code.

Who We Are

A small studio that takes it seriously.

Featherkite Studio is the app-building arm of Featherkite — a web studio that has been building and hosting for UK businesses since 2002. Today that means modern web apps, built and looked after by the same people who make them. No account managers, no offshore hand-off, no mystery about who is doing the work.

We build real, live products — not demos. CompliancePack for renewable-energy installers, Avrio the digital home logbook, and Women’s Rugby Data, a statistics platform we designed, built and run ourselves. Products people use every day.

How It Works

Three steps. No surprises.

01 / SPRINT

We map your workflow.

A deep-dive on how you actually work today. You get a blueprint and a fixed price.

02 / BUILD

We design and build.

A focused sprint on a modern, proven stack. One clear video update every week.

03 / LAUNCH

Your app goes live.

Deployed on managed hosting. Your team starts using it the same day.

Questions

Asked and answered.

Why fixed price?

Because hourly billing rewards slow work. We scope carefully, price honestly, and carry the risk of our own estimates. Anything outside the agreed scope gets quoted separately before we touch it. No surprise invoices, ever.

Who owns the code?

You do, outright. Every line of code is yours once the build is paid for, hosted with us or anywhere you like.

What if I need changes later?

Small fixes are covered by your maintenance plan. New features are scoped and quoted as mini-projects, on the same fixed-price principle.

Is my data safe?

Your app runs on enterprise-grade infrastructure, encrypted and backed up. Featherkite is ICO-registered and GDPR-compliant.

What do you build with?

A modern, proven stack: Next.js, Supabase, Stripe, chosen for speed, security and longevity. No legacy tech, no lock-in to obscure platforms.

We're not sure an app is what we need.

That's exactly what the £495 Scoping Sprint is for. Worst case, you walk away with a professional specification of your own business processes, useful whoever you build with.

Start a Project

Tell us what's broken.

Two minutes. Tell us about your business and the workflow that's costing you time. We'll tell you honestly whether an app fixes it, and exactly what it costs.

No obligation. No pushy follow-up. If an app isn't the right answer, we'll say so.
