AI engineering for SMEs, enterprise and the public sector
Our product. One governed picture of your business, under the AI tools your team already uses.
From £75 a user a monthA senior engineering team on subscription, for one product. Send as many requests as you need over Slack or Teams, and we work through them asynchronously.
£15,000 a monthFor leadership teams without an AI lead. We set the direction, connect your systems and get your people using AI on real work.
Scoped with youAn AI-driven scan of your software, checked by a senior engineer, with a ranked list of fixes. Not a CREST penetration test.
£1,000, one-offA named team working inside your environment to build one substantial system.

How we work
How an engagement runs
Stage 1
We look at what your team does today, where time is lost and what a useful improvement would look like.
You hold at the endA clear problem, a practical first scope and a way to judge the result.
Stage 2
We map the workflow and test the approach with the people who will use it. Data, access and review requirements shape the design.
You hold at the endA first design, an engineering plan and agreed responsibilities.
Stage 3
We build the system and check its behaviour against your work. Your team can see progress and help identify what needs to change.
You hold at the endWorking software, evaluation results and a clear view of its limits.
Stage 4
We agree how the system will be supported, who owns each part and how improvements will be prioritised.
You hold at the endDocumentation, an agreed support plan and a practical improvement backlog.
Dedicated engineering and AI transformation both run this way. Read the method in full
What we build and run ourselves
A Rust engine holds each organisation's records and agreed definitions in memory and works out every figure itself, with a certificate tracing it to its records. No AI model does the arithmetic.
Rust · semantic model · access ledger
Open-weight models served from dedicated UK or EU infrastructure, with a draft model for speed and adapters trained on real task trajectories.
Open-weight models · LoRA · speculative decoding
Each organisation's Twin runs on its own dedicated server, released through one pipeline: checks, one test run on the release, staging, then production on the same build.
Hetzner · immutable images · blue-green releases
Long agent sessions are claimed, leased and streamed, so a deploy or a dropped connection never loses or repeats the work.
Electric · durable streams · Postgres
Recurring work written as Python runs isolated, with no network and no secrets, and replays accepted results rather than redoing them.
Python · isolated sandboxes
One service holds the provider credentials, routes each call, and records what it used. A pinned model is the model that answers, or the call fails visibly.
Model gateway · routing · usage receipts
Runs, model calls and refusals are traced across every server into one store, and missing telemetry reads as unknown, never as healthy.
ClickStack · OpenTelemetry
The Twin and our fleet are operated through CLIs built for people and agents alike: JSON out, explicit writes, every change naming its organisation.
Twin CLI · Fleet CLI
A desktop client drawn natively in Rust, in development, alongside the Twin's web and iPhone apps.
Rust · native UI
