Sovereign/Private AI · EU

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

Custovault connects an AI employee to your systems of record — on-prem SQL, SAP, document flows, market feeds — so it answers 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.

providers named Critical ICT Third-Party Providers by EU regulators — incl. AWS, Azure, Google Cloud.

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, to name a few — 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.

Isolated 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.

This is depth × permission — 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

How we deliver: Build, Run, Expand.

01

Build

The setup project · you own the result

A defined project: we audit your data sources, deploy connectors, build the pipelines and fine-tune your model to your documents and house style — you own the result. Fixed scope, agreed up-front estimate, weeks not months.

ON-PREM SQL / ORACLE SAP FILES / SHAREPOINT EMAIL / M365 MARKET & EXCHANGE FEEDS
02

Run

The subscription · operated for you

A dedicated EU tenant running curated open-weight models (e.g. Mistral), fine-tuned to you — output in your house style. Ask-your-data chat, scheduled reports on live data, document processing, an OpenAI-compatible API. We handle MLOps, monitoring, security and DORA artifacts — plus a Client Operating Pack: the usage SOPs, prompt rules and guardrails that keep answers reliable and current. You subscribe to an operated AI employee, not software you run yourself.

Expand

New use cases · on demand

Once you're live, add business tasks or extend the solution. We scope it, estimate it, and deliver against timesheets — no open-ended commitment. The compliance layer — your keys, isolation, DORA artifacts and exit plan — is included throughout, not a separate stage.

NEW USE CASES MORE SOURCES & USERS SCOPED & ESTIMATED NO LOCK-IN
Service & continuity

Free to leave. No reason to.

The era of locking clients into platforms is over. We keep you by being worth keeping — and we prove you can walk away.

01

Your team, trained

Onboarding, prompt playbooks and usage SOPs are part of the product. We tune how your people work with the AI employee — workspace structure, what to ask, what not to trust — so it gets used, and used safely.

02

Never silently outdated

Models, connectors and the platform are upgraded on a published cadence — re-benchmarked on your evaluation set before rollout, with release notes your team actually receives. You will never discover you've been six months stale. Refreshing your own fine-tuned model on new data is scoped separately.

03

A human all along the way

A named contact who knows your setup — from first connector to board audit. Support is how we earn the subscription, not a footnote in the contract.

04

Built to survive us

Key and model-weight escrow, a documented exit plan, standard formats. If Custovault disappeared tomorrow, your tenant keeps running and everything in it is yours. That isn't a caveat — it's the design.

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, isolated 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

Leave any time

Exit tooling, a documented exit path and key & weight escrow. Leaving must be easy — otherwise staying means nothing. DORA-ready evidence pack included.

07

Read-only by construction

Custovault reads and reasons over your data; it has no write path back to your systems of record. Every output goes to a person to act on.

08

Grounded, or it refuses

Where numbers matter the engine is deterministic — it answers only from your own data or explicitly declines, and never invents a figure. Every answer carries a link to its exact source, checkable by hand.

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