How we work

Six habits behind 90% client retention

These are not posters on a wall. They are the things clients mention when they renew, and the things we check ourselves against at every retrospective.

01

Engineers on the call

Clients talk to the people doing the work from the first conversation. No account manager relaying messages.

02

Say no early

If the budget, timeline or approach will not get you where you need to go, we tell you before the contract, not after.

03

Write it down

Estimates, assumptions, decisions and weekly progress go in writing, so your stakeholders see exactly what we see.

04

Ship small, ship often

Short sprints and a demo at the end of each one. You always have something working to look at.

05

Your IP, your accounts

Code, repositories and cloud accounts belong to you from day one. Handover is a formality, not a negotiation.

06

Stay for the boring part

Fixes, performance and the next version after launch. Most of our clients have been with us for years.

AI in our delivery

AI speeds up the work. Our engineers own the result.

We use AI tools at every stage of a project to cut the repetitive work and shorten sprints. Every output is reviewed by a senior engineer before it reaches your codebase, your users or your report.

01

Discovery and scoping

AI summarises your documents, calls and existing code, and drafts user stories and a first estimate.

Engineer owns The final scope, estimate and risks
02

Design and prototyping

Clickable prototypes and UI variations in days, so you react to something real early.

Engineer owns UX decisions and the design system
03

Build

Code assistants handle boilerplate, tests and refactors, which frees engineers for the hard parts.

Engineer owns Architecture and a line-by-line review
04

Testing and QA

Generated test cases, regression suites and automated checks run on every release.

Engineer owns Test strategy and release sign-off
05

Reporting and handover

Weekly progress notes, release notes and documentation are drafted from the actual work.

Engineer owns What goes to you, in plain language
Your code and data are never used to train public models
Only tools approved for your project, in line with your security policy
Every AI-assisted change is reviewed by a senior engineer
You can limit or switch off AI use on your project at any time
