Local AI · Based in London
Own the brain that runs your back office.
It reads, extracts and files your documents the second they arrive — on a box you own. Nothing leaves.
Every other AI wants your data. Crucible runs on yours.
Every invoice you hand to a cloud AI is a lease payment on someone else’s computer — and they can meter you, change the terms, or read your books whenever they like. Crucible is the other option: a box in your building, the data on your network, the bill fixed. You own it.
Meet Crucible
Watch it read a document — and file it.
It reads what arrives, pulls out the numbers and names, checks them, and files a clean record. Here’s a single invoice, handled.
How Crucible reads and files a document
Extracted · validated
Example: an anonymised supplier invoice.
Why local
Three reasons it has to be yours.
It can be switched off — and not by you.
The model your cloud workflow runs on was never yours. Vendors retire models on their schedule, and access has been cut off for every customer at once. On your own hardware, no memo three time zones away can stop your back office.
The bill climbs as you grow.
Metered AI charges you more for every document you process — so the better you do, the more it takes. Crucible is one flat fee. Process ten documents or ten thousand; the invoice doesn’t move.
You’re paying frontier prices for filing.
Reading an invoice, pulling a total, filing it — that’s exactly where local models now match the cloud giants. You’re being charged data-centre rates for work a box in your office does for the cost of the electricity.
How it works
From inbox to filed record. Automatically.
Crucible runs one relentless loop on every document that arrives — so the pile stops growing.
- 01
A document arrives
Invoice, order, case file, claim or statement — by email, PDF, scan or portal.
- 02
It reads and classifies it
Crucible works out what the document is and which workflow it belongs to.
- 03
It extracts the data
Numbers, names, codes and dates — pulled out clean, with no manual keying.
- 04
It flags what it isn’t sure of
Anything it isn’t confident about waits for a person. You sign off the exceptions; everything else flows.
- 05
It files the record
Structured data pushed straight into Sage, Xero, Proclaim or your ERP.
- 06
You get your time back
The intake that used to eat a person’s week runs quietly in the background.
Prove it to your auditors
Your data never leaves the building.
Every document is processed on hardware on your premises. There are no egress routes to third-party AI — and your IT or compliance team can audit the traffic to prove it. We encourage it.
The product
A managed appliance. You don’t maintain it.
We handle the hardware, the model, the updates and the support — remotely. Your team turns on a workflow; they don’t babysit a GPU.
You own the hardware
A box in your building, on your network — not a tenancy on someone else’s server.
One flat fee, no meters
Never per token, page, document or seat. Your bill doesn’t punish you for growing.
Tuned to your documents
Customised to your invoices, part numbers, precedents and chart of accounts — not a generic model.
Auditable by your team
No egress to third-party AI. Your IT or compliance team can verify the traffic for themselves.
Sectors
Built for the firms the cloud locked out.
We start where the data wall is highest. The loop is the same underneath; only the documents and the regulator change.
Manufacturing
Designs, specs and pricing bound by NDAs and export-control rules — the kind of data that's safest on hardware you own.
Law firms
Privilege and SRA confidentiality make sending a client file to a third-party AI a professional-indemnity problem.
Accountancy
You hold a client’s entire financial life. Casual cloud processing is a risk you can’t take — and MTD only adds volume.
Healthcare
Special-category patient data, active ransomware targeting, and an absolute duty of confidentiality.
Construction
NDA’d contract documents, the UK’s largest SME sector, and sites where connectivity can’t be relied on.
The company
Hold us to our word.
We build local AI for the back office, from London. We’re early, and we say so — no inflated logos, no invented numbers. What we offer instead are commitments written into the engagement, not the marketing.
A delivery date in writing
Scope and go-live agreed up front, on paper — not an open-ended engagement.
A flat fee, never a meter
One monthly price. Never per token, page, document or seat.
No lock-in, ever
It runs on your hardware, with your model weights, on your own network — no cloud dependency and no kill-switch. The capability you buy is yours to keep.
The questions sceptics ask first.
We already have an ERP or document system.
- Crucible doesn’t replace Sage, Xero or Proclaim — it feeds them clean, structured data from the documents that never made it in. No rip-and-replace.
What if the AI gets it wrong?
- Every extraction has a confidence threshold. Below it, the document waits for human review. You see everything it touches and sign off the exceptions. It’s a filter, not a black box.
How do we know the data really stays on-site?
- Your IT or compliance team can verify the network traffic — there are no egress routes to third-party APIs. You can audit it, and we encourage it.
We have no IT team to run it.
- You don’t run it. Crucible ships as a managed appliance: we deploy, monitor, update and support it remotely. You simply turn on a workflow.
Are we ever locked in to Crucible?
- No. It runs on your hardware and your model, on your own network — independently of any cloud and of us. No kill-switch, no vendor you can’t leave. The capability you buy is yours to keep.
Stop renting your business’s brain. Own it.
