Sovereign private AI · EU

An AI employee that knows your business.
In your EU tenant, under your keys.

Custovault connects assistants and task agents to your systems of record — on-prem SQL, SAP, document flows, market feeds — so they answer what public chatbots physically can't. Fully managed, EU-hosted end to end, and built so your data never leaves your control.

Why now

Three forces are converging at the same time.

01

AI is becoming operational

Companies want to run AI on their own data — fraud, risk, ops, documents, R&D — not just experiment with public chatbots.

02

Regulation is tightening

DORA (finance), GDPR and the EU AI Act push data control, third-party risk, auditability and exit planning up the board agenda.

03

Data sovereignty matters

Putting sensitive or proprietary data on US hyperscalers raises jurisdiction, access and control questions that are now hard to ignore.

~22,000

EU financial entities now face DORA third-party and concentration rules.

1

place your data should live: under your keys, your control — not a shared AI cloud.

What you gain

Depth public AI can't reach — and permission to use it.

Two dimensions that only work together. Public chatbots have neither; enterprise assistants on US clouds have at most one.

01 · Depth

It knows your business.

Connected to your systems of record — on-prem SQL and Oracle, SAP, files, market feeds — it answers and reports on complete, fresh data that public chatbots physically can't produce. Not "files someone uploaded last month": live, connected, whole.

02 · Permission

Your compliance can say yes.

Single tenant, your keys, EU jurisdiction end to end, audit trail and DORA artifacts. Your fine-tuned models belong to your tenant — never shared, never reused — so training on your own data is legally clean.

The vault isn't a second product — it's the licence for the depth. Sovereignty is what makes it legal to hand an AI your real data and train models on it. Each dimension is worthless without the other.
How it works

Three layers. One managed contour.

01

Connect

Mini-implementation · fixed scope

A productized integration project: we audit your data sources, deploy connectors and build the pipelines that keep your tenant's data complete and fresh — ready for RAG and fine-tuning. Fixed scope, fixed price, weeks not months.

02

Operate

Your AI employee · subscription

A dedicated EU tenant running curated open-weight models (e.g. Mistral) and a bespoke fine-tune on 100–200 of your reference documents — output in your house style. Ask-your-data chat, vertical task agents, scheduled reports on live data, an OpenAI-compatible API. We handle MLOps, monitoring and support.

Prove

Compliance layer · included

Technical provability — your keys, tenant isolation, confidential computing on the roadmap — plus ready DORA artifacts: ICT third-party register, same-day incident reporting, a documented exit plan. Key and model-weight escrow. Your board buys risk removal, not infrastructure.

Use cases

Contract & policy review

Faster reviews, lower legal cost.

03

Support copilot

Better detection, fewer losses.

05

Data that can't go to public AI

Economics

Build it yourself — or get it managed.

The honest alternative to Custovault isn't a $300/month chatbot seat. It's an integrator, pipelines, an ML team and governance you run yourself.

Build in-house

  • 2–4 specialists (ML, infra, compliance): €250–500k / year
  • Hardware capex + reserved GPU commitments
  • 9–12 months before anything is in production
  • You own all DORA / audit / exit evidence yourself
  • Ongoing hiring, retention and maintenance risk

With Custovault

  • Opex only — GPU cost shared, no capex
  • Live in weeks on a managed platform
  • Key control and tenant isolation included
  • DORA-ready evidence pack out of the box
  • Predictable monthly cost, scale up or down
Typical result: skip €300k+/year of in-house cost and reach production in weeks instead of a year.
For your compliance team & board

Your data stays yours. Provably.

01

You hold the keys

Bring your own keys (BYOK/HYOK). Custovault physically cannot decrypt your data.

02

Only you train & infer

Only you run training and inference on your data — nobody else, ever.

03

Data never leaves

No egress to third parties. Never used to train shared or foundation models.

04

Isolated tenant

Dedicated single tenant; confidential computing on the roadmap — so even the operator can't see data in use.

05

EU jurisdiction

Hosted in the EU, under EU law, with full audit logs across every layer.

06

Portable — no lock-in

Exit tooling and a documented exit path, plus a DORA-ready evidence pack.

What we don't promise: that you'll "pass supervision". We give you the contour, the artifacts and reversibility — the supervisory conversation stays yours, with evidence in hand.
