Client work by Mercury Labs, the team behind your Twin.

Agree the meaning. Reuse the understanding.

Which records describe the same customer? What counts as overdue? Your Twin connects identities, relationships and definitions, then checks the calculations against your data.

How your Twin is built and checkedSix steps · separate review

01Find the connections
Find records that describe the same customer or supplier across systems. Sensitive values are protected before comparison.
02AI proposes a design
AI proposes relationships and definitions, such as what counts as overdue, using descriptions and measurements rather than raw records.
03Software writes the code
Software turns the proposed definitions into calculations and tests.
04Check against your data
Results must reconcile against your source data, such as invoice balances and totals.
05A separate AI reviews it
A different AI evaluates the work. It cannot rewrite or approve the design it reviews.
06Release only checked work
Work that fails the checks is blocked. The released version stays off until you switch it on.

Understanding the work should not mean chasing updates and rebuilding spreadsheets. Your Twin connects the pieces across the systems you already use.

Server + storage

Your Twin

Private model

Server, storage and model processing together.

We connect the systems. You help define the result.

Start with one important workflow. In two focused weeks, we connect its systems and check the results with your team. We agree setup, ongoing support and changes with you.

Connect priority systems
We agree the question, connect the systems it needs and start with read-only access.
Build and check your Twin
Your Twin connects the records, defines the calculations and tests them against your data. Work that fails the checks is left out.
Review the Twin, then switch it on
Check the result against real business examples with your team. The release stays off until you switch it on.

What you control, and how it works.

Where your data goes, what it costs and what you control.

Your Twin reads the systems you connect without changing the original records. It runs on a dedicated server for your organisation. Keep managing the original records in your existing systems.
When you use an external AI provider, the business information needed for that request is sent to the provider configured for your organisation. We agree the connections, access and model provider before setup.
Subscription: Core starts at £2,000 a month, Scale at £5,000 and Enterprise at £15,000. Each includes a dedicated, managed deployment.
AI usage: model credit packs start at £250 a month.
Optional engineering: Mercury Labs engineers can help with setup and integrations at £1,200 a day.
See the pricing page for what each plan includes. We agree the work and costs for your teams and systems before starting.
Connected records refresh on the schedule agreed for each source. When a business definition changes, it is checked and released for review, with version history. Your team and approved AI tools keep using the same shared understanding.
Your subscription covers the managed deployment and support included in your plan. We agree setup, additional connections and engineering work with you. Expanding the Twin starts with the next useful question, rather than rebuilding it for each AI tool.
Channels bring related records, saved views, files and conversations together. Organise them around areas such as Commercials, Delivery or Finance, then work through a review or follow-up with the supporting records close by.
Your Inbox is where you review incoming updates and suggested actions, with the context behind them. Start an agent session from an item when it needs more work. What you can see and do depends on your access.
We need to check your requirements with you. Your Twin starts with read-only connections and access limited to your organisation. You can review each tested version of the Twin before it is switched on.
The standard checked query path does not include browser, terminal or write access. Your team still needs to approve where data and model requests go, how long evidence is kept and how the deployment is operated.
It tells you when the checked Twin cannot answer. This path (called a governed answer) identifies the published definition, version and source freshness it used. If the question or evidence is unsupported, it returns “not supported”.
An agent can still explore the underlying records within its permissions. That exploratory work is not labelled a governed answer and needs to be reviewed accordingly.

Two ways to start

Start with the question your team keeps chasing.

Your first workflow

Show us a recurring report, an awkward handover or a decision that takes too long to prepare. We’ll explore where your Twin could help and agree a useful starting point.
