Software shaped around how your business already works.

Internal tools, client portals and SaaS products, built week by week from a written brief and a fixed price. We build and run five web apps of our own, so this is our everyday work.

Three kinds of web app we build.

01

Internal tools and dashboards

The spreadsheet that runs your business, turned into software: the right fields, the right people seeing the right things, and reports that build themselves.

Right forTeams running operations on spreadsheets, email threads and copy-paste.
02

Client portals

One place your customers log in to see their orders, documents, bookings or progress, so your team stops answering “where are we?” by email.

Right forService businesses that send the same updates to every client.
03

SaaS products

A product you sell to other businesses: accounts, roles, billing and an admin side, built to launch small and grow without a rewrite.

Right forFounders with a proven idea and customers waiting for it.

Scope.

Before anything is built, we map your workflow with you and write it down: what gets built, what doesn’t, what it costs and when it lands. Nothing starts until you approve it.

The workflow
How the work moves today, step by step, and where it slows down.Software that copies a broken process just breaks faster.
People and roles
Who uses it, what each person needs to see, and what they must never see.Permissions decided early are cheap. Bolted on later, they are not.
Data and tools
Where your data lives now and which tools it has to talk to.Integrations are where most timelines slip, so we price them first.
What done looks like
The one or two measures that tell you it’s working.A clear finish line keeps the scope, and the price, honest.
You getA written brief, a fixed price and a timeline. Go ahead, and Sprint starts from that brief. Don’t, and the brief is still yours.

Built to last. Handed over so you can run it.

What every web app build includes, whatever its size.

Weekly demosEvery week of Sprint you get a working link to click through, not a status report.
Your code, your accountsThe code and the hosting live in accounts you own. You are never locked in to us.
Version controlEvery change is recorded and reviewed, so anything can be traced or rolled back.
Accessible by defaultKeyboard, screen reader and contrast checks are part of the build, not an extra.
Measured speedWe test it on a mid-range phone and a slow connection before launch, and fix what fails.
Training at handoverYour team learns to run it, and you get written notes to keep.

You see the price before we write a line of code.

Web app questions.

Anything else, ask us on a discovery call.

Maybe. If Slotly, Stockroom, Dealflow, Cortex or Crewspace already does most of what you need, starting there is faster and cheaper, and the studio can tailor it later. If your workflow is genuinely your own, a custom build is the better fit. We will tell you which on the call.

Bring us the spreadsheet that runs your business.
