Build & Run · UK & London

We build what you ask for. And advise on what is worth building.

From one Agent to a full bespoke app, engineered around your data, your flows and the hours you most want back. We scope the work, advise on the order, build it and run it. UK team, no agencies, no outsourcing.

What we build

Four ways we make it real.

Secure

Code & security review

OWASP audit, CVE scan and an authentication review, with a prioritised list of fixes.

Build

Web applications

Bespoke web apps in React and Node.js, cloud-deployed and built exactly to your spec.

Automate

Automation & API integrations

Custom pipelines that sync your systems automatically, with no manual data entry.

AI agents

Custom AI agents & LLM integrations

AI agents for business: receptionists, document handlers and ops copilots, plus RAG pipelines built on your data.

AI agents for business

An agent is a member of staff you configure once.

An AI agent is software that does a job, not a chatbot you have to prompt. It watches for work arriving, does the routine part, and hands the judgement calls to your team. We build them on your systems and your data, UK-hosted.

Not sure which workflow to start with? That is exactly what the 90-minute AI readiness audit answers.

AI receptionist

Answers calls and enquiries 24/7, books appointments into your calendar and hands anything complex to a person, with a transcript.

Document agent

Reads invoices, contracts or claims as they arrive, extracts what matters into your systems and flags the exceptions for review.

Ops copilot

Watches your inbox, CRM and job board, drafts the routine replies and chases the loose ends, so the morning admin is done before you sit down.

Built on the platforms the world trusts

Why it matters

Security is not optional

Most web apps ship with at least one critical vulnerability. We review before we build.

Known flaws cause breaches

The majority of breaches exploit known, unpatched issues, exactly what an audit catches.

Automation pays back

Well-designed workflow automation returns many times its cost in hours saved.

AI cuts the grind

Custom AI pipelines cut document-processing time and cost dramatically.

What you get

A finished product, not a prototype.

Tech-stack selection and an architecture document
UI/UX wireframes and a design system
Responsive React / Next.js frontend
Secure Node.js or Python backend with a REST/GraphQL API
PostgreSQL or SQLite database with migrations
Authentication (OAuth 2.0 / JWT)
Automated test suite (unit + integration)
Cloud deployment with a CI/CD pipeline
Technical documentation and a handover pack
3-month support window after launch

Internal tools built to spec take about 8 weeks, a fraction of the time and cost of a traditional product agency. And the full source code is yours on day one, with no vendor lock-in.
