London · Design and engineering since 2014Taking new projects from Q4 2026

Independent digital product studio

We design and build mobile apps, web platforms, AI features and the backend behind them.

A senior London team with twenty years of shipping products for Virgin, Shell, Heycar, Lloyds Banking Group and ClearBank. You work directly with the people doing the work.

Shipped for

Selected products and platforms we’ve helped design, build and ship.

What we do

Four pillars, one team accountable.

Most projects need two or three of these. They are priced and planned together, not handed between agencies. No account manager, no relay of briefs: you speak to the people writing the code.

Services in detail

A mobile product interface being used in a calm architectural space

Cross-platform apps that feel native.

One codebase, both stores, no compromise on gesture, motion or platform convention. Heycar, Virgin Trains Ticketing, Virgin Red and Shell Fleet all shipped on this stack.

What we deliver

  • Product design and prototyping
  • React Native / Expo build
  • Store submission and release management
  • Crash, analytics and OTA update pipeline

Platforms that convert and rank.

Server-rendered React with a real design system behind it. Lloyds Mortgages and ClearBank were rebuilt on this approach without a drop in traffic.

What we deliver

  • Design system and component library
  • Next.js / TanStack Start build
  • Core Web Vitals and SEO engineering
  • CMS integration and editor training

A field of fragments resolving into a precise digital grid

LLM features that survive real users.

Scoped against a real user journey, not a demo. AMiSi.ai runs production generation workflows, while Francis embeds conversational AI inside regulated financial experiences.

What we deliver

  • Feature scoping and model selection
  • Chat, generation and automation flows
  • Evals, guardrails and cost controls
  • Streaming UI and fallback states

A secure, illuminated data-centre corridor

The plumbing behind the interface.

APIs, auth, payments and pipelines. Ticketing and banking workloads delivered under FCA and PCI constraints, with runbooks the inheriting team can actually use.

What we deliver

  • API and BFF design
  • Auth, payments and third-party integration
  • Infrastructure as code, CI/CD
  • Observability and on-call runbooks

AI, in production

Features that ship, not demos.

How we scope AI
01Custom workflowsAutomations that run without a person watching, and stop when they should. Drafting, triage, chasing, reconciliation — the work nobody has time for.Scoped triggers and stop conditionsA human approval step before anything leaves the buildingCost ceilings and per-request loggingRetries, dead letters and an audit trail
02Custom skillsTools the model can actually call: your APIs, your data, your rules. Not a chat box bolted onto a product.Typed tool schemas against your own endpointsPermissions per skill, per roleAn eval per skill, run in CIGraceful fallbacks when a tool is down
03AI-ready codebasesRepositories a model can navigate without guessing: typed boundaries, written conventions, and tests that catch drift before a release does.Conventions documented where agents read themTyped API contracts as the source of truthPrompt and skill versioning alongside the codeAn eval suite that fails the build, not the customer
What “AI-ready” means in the repoShipped on every AI engagement

How we know it will hold up.

Four things we can show you

The working relationship

Senior people. Clear decisions. No handovers.

  1. 01Direct access

    The people in the room are the people doing the work.

    Scope, design and engineering decisions stay close together—without an account-management relay.

  2. 02Visible progress

    You see the product running throughout the engagement.

    Regular working builds make progress visible and surface difficult decisions while they are still inexpensive to change.

  3. 03Clean ownership

    The code is yours from the first commit.

    Delivery includes documentation, a support window and a codebase the next team can actually understand and run.

How it works

Six steps, no surprises.

  1. Objectives, audience, competitors and constraints, written down before anything is designed. This is where the expensive mistakes get caught.

Writing

Notes from inside the build.
