UK based AI development studio
Websites and platforms, built by people who’ve delivered them for twenty years.
Test Mode is run by senior people who have built and run digital agencies for two decades, delivering for adidas, Google, Samsung, Channel 4 and Emirates. We use modern enterprise AI tooling to get from brief to launch faster than you’re used to, with nothing skipped and no junior layer in between.
- Senior team on every project, first meeting to launch
- Your stack, your CMS, your code, from day one
- Faster delivery. Same standards. Nothing thinned out

Prior project experience
Why Test Mode
Twenty years of other people’s deadlines.
Run by people who’ve run agencies
Two decades building and running digital studios. We know what clients expect, what a slipped deadline actually costs, and what it feels like when something breaks the week it launches.
Senior from the first meeting
Strategy, design, technical direction and QA are done by the same senior people throughout. No handover to a junior team once the pitch is won.
Faster, not thinner
Our build process uses modern tooling to remove the slow, repetitive parts of development. Senior engineers direct it and review every line. Weeks instead of months, with nothing skipped.
Yours, properly
Your own repository, a normal CMS you can edit, no lock-in to any tool or to us. Any developer can pick it up in five years’ time.
The question you came here with
Are we an AI agency?
We are a digital studio that uses AI where it is actually good: writing code, under the direction of senior engineers who review every line. Strategy, design, QA and the decisions are human, made by the same people who have done this for twenty years. If you searched for an AI development studio, that is what we are. We just don't lead with it.
How it works
Brief to launch, without the dead weight in the middle.
- 1
Brief
A senior person, round a table with you. Scope, stack, dates, risks: said out loud, early.
- 2
Design
Proper custom design you sign off before anything is built. A person with taste, not a template.
- 3
Build
Modern tooling does the repetitive work at speed. Senior engineers direct it and review everything.
- 4
Launch
QA across every device, a clean handover, and the same people on the phone the week after go-live.
What we build
Whatever the scale. Whatever you’re already running.
Questions we get asked
Straight answers.
Who actually does the work?
Senior people who have built and run digital agencies for twenty years, and the teams they have worked with for most of that time. There is no junior layer between you and the people making the decisions.
Do you use AI?
We are a digital studio that uses AI where it is actually good: writing code, under the direction of senior engineers who review every line. Strategy, design, QA and the decisions are human, made by the same people who have done this for twenty years. If you searched for an AI development studio, that is what we are. We just don't lead with it.
How is it faster without dropping quality?
The slow part of most projects is not the thinking, it is the repetitive mechanical work in the build. We use modern tooling to take that out, directed by senior engineers who review everything before it goes anywhere near live. Strategy, design, QA and launch are done by people, the same way they have always been.
Do you offer design services?
Yes. We have our own creatives, and they take you from the brief through to finished Figma files. You review and sign those off before any development starts, the same process a good agency has always run.
Do you use AI for design?
No. Design is done by people, in Figma, the way it always has been. You get Figma files to sign off before anything is built. Where we do use modern tooling is in the build, and senior engineers review all of it.
Do we own the code?
Yes, from day one. It lives in your own repository with your name on it. Any developer, ours or one you hire in five years, can pick it up.
Can we edit our own site?
Yes. We build on whatever content system suits the job: WordPress, a headless CMS like Sanity or Contentful, Shopify, or a custom admin. You log in and edit, exactly as you would expect.
Which technologies do you build in?
Whatever you are already running, or whatever the job actually needs: WordPress, Shopify Plus, Salesforce, headless commerce, custom Node or .NET backends, payment gateways, booking and stock systems, CRM and ERP integrations and single sign-on.
Do you work with agencies as well as brands?
Yes. A lot of our work is as the build partner behind other agencies, white-label, in the client's existing stack. We also work directly with brands.
Where are you based?
We are UK based and fully remote, with addresses in London and Liverpool, and we work with clients across the whole of the UK and internationally.
