Process

How it works.

  • 1. Send access and questions. You share access to the system and the questions it has to answer well. We agree the scope and the price in writing.
  • 2. Test and review. We run the test set against the live system and review answers, retrieval, tool calls and failure cases.
  • 3. Report and fix list. You receive a written report with findings and a prioritised fix list your team can act on.
Questions

Before you book.

Are the prices fixed?

Yes. Scope and price are agreed in writing before work starts, and all prices exclude VAT. Work outside the agreed scope is quoted separately before it starts.

How long does it take?

The LLM Production Check delivers its report in 5 working days. For the other packages the timeline is part of the written scope.

What happens to our data?

Access and data are used only for the agreed test. We can work under your NDA, and the scope records what we may access and when access ends.

What if you find nothing?

You receive a report that shows what was tested and that it passed. That is evidence too: for your release decision and, where relevant, for EU AI Act documentation.

Does this cover the EU AI Act?

The Governance Pack covers inventory, risk classification, logging, the technical-file skeleton and a gap list. It is engineering evidence, not legal advice.

Can we try it first?

Yes. Send five questions your system must answer well. We run them and tell you what we see, free of charge.
