Five principles we hold toA senior team that stays close to the problem and builds for the long run.
01The people who win the work do the work.
02We start with the people doing the work, not a solution.
03We test the data before we promise the benefits.
04Every pilot ends in a clear go or no-go.
05We build systems your team can own and keep running.
What we do
Six capabilities, one senior teamStrategy, design and engineering, with a team that stays close to the work.
01
Strategy, discovery and feasibility
We find where AI can genuinely change the work, check the data and constraints behind it, and turn the best opportunities into a plan you can act on.
02
AI products and applications
We design and build complete products around the people who use them, from specialist internal tools to services for your customers.
03
Data and knowledge systems
We connect your documents, databases and systems so people and AI work from the same current information, with each person seeing only what they should.
We run this ourselves: the Twin's graph engine answers from live records with a certificate.
04
Agents and workflow automation
We build agents that gather evidence, use the tools you approve and move work forward, with clear limits and a person to hand over to.
We run this ourselves: the Twin's agent runs survive restarts and deploys.
05
Evaluation and governance
We make quality and safety measurable: tests on real examples, access controls and a record of what the system did and why.
We run this ourselves: the Twin's answers are tested on agreed sets before each release.
06
Deployment and managed operations
We deploy into your environment, then monitor, support and improve the system as real users and changing data arrive.
We run this ourselves: one customer per dedicated server, released through one pipeline.
What we build and run ourselves
We build our own product and run it in productionThe Company Twin is ours, end to end. The same engineering goes into the systems we build for clients.
Certified answers from a graph engine
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.
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.

Agent runs that survive restarts
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
Sandboxed Python workflows
Recurring work written as Python runs isolated, with no network and no secrets, and replays accepted results rather than redoing them.
Python · isolated sandboxes
Every model call through one gateway
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.

Monitoring built for AI
Runs, model calls and refusals are traced across every server into one store, and missing telemetry reads as unknown, never as healthy.
ClickStack · OpenTelemetry
Run from the command line
The Twin and our fleet are operated through CLIs built for people and agents alike: JSON out, explicit writes, every change naming its organisation.

How an engagement runs
Four stages, each with something you hold at the endValue is proved before anything is scaled, and each stage ends in a decision we make together.
Stage 1
Understand
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
Design
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
Build
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
Improve
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.
Systems built around the people who use themFrom national public bodies to manufacturing, financial services and health.

Cyber security certifications
Mercury Labs, the company behind the Company Twin, holds both certifications through its legal entity, Mercury Digital Assets Limited. Scope: whole organisation.
The Company TwinShared business understanding for your team and AI tools.
It connects the AI tools your team already uses to the systems you run, so every answer works from live records, and each person sees only what they are allowed to.
