Early access programme now open — 12 firms onboarded.
The Problem
Every organisation handling sensitive data faces the same three failures.
Generic AI forces an impossible choice. Diana eliminates it.
Your data leaves your walls.
Every time someone uses ChatGPT, Copilot, or Harvey for sensitive work — M&A data, patient records, client financials — that data travels to a server they don't own. A privacy policy says it won't be misused. That is not a guarantee.
Fifteen tools. No memory. No execution.
Generic AI lives in a browser tab, disconnected from the systems where real work happens. It advises. It does not act. Professionals still move data manually between systems, wasting hours on tasks that require no judgement.
Your best experts' knowledge disappears.
When a senior partner retires, thirty years of methodology disappears. It lives in their head and their billable hours — nowhere else. The knowledge that took decades to build is inaccessible the moment they are unavailable.
The Solution
Diana. One platform. Four things no competitor offers simultaneously.
Most AI tools pick one of these. Diana delivers all four — in a single sovereign deployment.
Runs inside your walls.
Diana ships as a physical appliance — a pre-configured box that lives in your IT room. Everything runs on your hardware. Nothing leaves. Not to train a model. Not to a shared server. Not anywhere.
Trained by world-class experts.
Agents are not generic. They are trained by elite practitioners — M&A lawyers, senior analysts, specialist advisors — who encode their methodology through Diana's Expert Marketplace. The agent thinks like them. Not like the average of the internet.
Executes. Does not just advise.
Diana has full read/write access to your enterprise stack — Salesforce, DocuSign, Gmail, your document systems. It does not suggest what to do. It does it. Workflows that took hours complete in 25 seconds.
Powered by sovereign intelligence — not a public model.
Diana runs on Small Language Models — compact, powerful AI that operates entirely on your hardware without requiring cloud infrastructure. Faster than public models for specialist tasks. Cheaper to run. And physically incapable of sending your data anywhere, because they never connect to the internet to work.
How it works
From delivery to live in a day.
We ship the box.
Diana arrives as a pre-configured appliance. Your IT team plugs it into your network. No cloud accounts. It is ready in hours.
Connect your tools.
Diana integrates with what your team already uses — Salesforce, DocuSign, Gmail, Google Drive, Slack. Full read/write access. Every action is logged in real time.
Your agents run. Your data stays.
Expert-trained agents execute workflows autonomously. Your team reviews and approves. Everything happens inside your infrastructure. Nothing leaves your building. Ever.
The Diana appliance
Your building. Your silicon. Your rules.
Diana doesn't live in a data centre you've never visited. It lives in yours.
- Dedicated silicon. Your workloads run on hardware in your environment — the same class of compute you'd trust for any other sensitive system.
- Mini datacenter, your building. A compact rack beside your existing infrastructure. Your IT team owns it. Your compliance team can audit it. Nobody else can touch it.
- Zero mystery. Zero cloud. No undisclosed server region. No multi-tenant inference pool. If it is not inside your perimeter, it is not processing your data.
- Air-gapped on request. For environments where even a local network connection is too much, Diana supports fully air-gapped deployment. No network. No exposure. Absolute sovereignty.

The Expert Marketplace
The world's best practitioners. Inside your infrastructure.
For the first time, elite professionals can separate their expertise from their time. A senior M&A lawyer trains a Diana agent on their methodology once. That agent then runs inside client environments autonomously — earning the expert royalties while they sleep.
