02 / HOW WE THINK

The detail is
the work.

A useful product is a series of decisions made well. What it should do. What it should leave out. How it behaves when real life gets in the way.

01

Start with the problem.

Understand the person using it and the job they need done. Give every feature a reason to exist.

02

Build the whole thing.

The interface, the underlying logic, the edge cases and the release. They all belong to the same job.

03

Keep paying attention.

Shipping is a milestone. Real use tells us what needs to happen next.

03 / WORK WITH US

Something worth
building properly?

We take on a couple of app projects at a time. Each needs a clear problem, a committed decision-maker and the budget to see it through.

From definition to delivery.

Most builds take six to ten weeks: product definition, design, engineering, testing and launch. Every project starts with a short, fixed-price definition phase, so the scope, the plan and what ongoing support looks like are agreed before the build begins.

Product & scopeInterface & experienceEngineering & testingLaunch & handover

Projects start from

£12,000

Definition sprint £1,500, credited against the build. Care plans from £250 a month.

  • A couple of projects at a time
  • One senior builder, end to end
  • iOS and Android from a single codebase

If that fits, send the problem, the people it's for, your budget and your timing. We'll tell you plainly whether it's a fit.
