SOVEREIGN AI INFRASTRUCTUREEUROPE / 2026

THE NEXT CRITICAL INFRASTRUCTURE LAYER

Europe should be able to run AI without surrendering control.

We build and operate the private AI layer inside your boundary—models, data, identity, workloads and the systems that keep them dependable.

01MISSION

Intelligence is becoming infrastructure.

AI is moving from experiments into the systems that organisations depend on. When that happens, the model is no longer the product. The boundary, the data path, the operating standard and the right to change direction become the product.

Kastral gives European organisations that control. We deliver a complete private AI capability, then stay responsible for keeping it ready.

02KASTRAL CORE

The control layer for sovereign AI.

One hardened foundation between your organisation and every model. Kastral Core turns infrastructure, identity, policy, knowledge and operations into a system you can put real work on.

01

Private model runtime

We run approved open-weight models on compute dedicated to your organisation—not behind a shared public API.

02

Organisational context

We connect the systems, knowledge and permissions that make AI useful inside real operations.

03

Governed execution

We give assistants and agents a controlled path to act, with policy checks, human authority and a complete record.

04

Continuous readiness

We monitor, patch, back up, restore-test and regression-test the entire capability after deployment.

03CAPABILITY

Put intelligence inside the operation.

We do not stop at infrastructure. We field the first high-value workloads on top of it and make them production-ready.

01 / ORGANISATIONAL INTELLIGENCE

Give every authorised person access to the knowledge the organisation already has.

Private search, grounded answers, synthesis and analysis across internal systems—with source evidence and existing permissions preserved.

KNOWLEDGERESEARCHDECISION SUPPORT
02 / DOCUMENT OPERATIONS

Turn document-heavy work into governed data and decisions.

Classify, compare, extract, review and route high-volume material without losing the original evidence.

EXTRACTIONREVIEW
03 / CONTROLLED AGENTS

Let AI act—inside explicit authority.

Connect models to tools and workflows with identity, approval gates, restricted actions and complete auditability.

EXECUTIONHUMAN CONTROL
04DEPLOYMENT

Fielded where control demands it.

The same Kastral Core can run on a dedicated European node or inside your premises. We design the boundary around the mission—not around a cloud product.

ARCHITECTURE AEU

DEFAULT

Dedicated European node

Single-tenant infrastructure in Belgium, Germany or France, privately connected to your organisation and operated end-to-end by Kastral.

  • Dedicated compute and storage
  • Private network path
  • EU-resident operations
ARCHITECTURE BON

RESTRICTED ENVIRONMENTS

On-premises appliance

Kastral Core installed inside your facility for environments where data, workloads or network traffic cannot leave the site.

  • Customer-controlled location
  • Offline-capable architecture
  • Kastral operating standard
05OPERATIONS

Capability is measured in readiness.

A private deployment only matters if it remains secure, current and recoverable. We own the operating burden after go-live.

06SOVEREIGNTY

Own the boundary.
Retain the evidence.
Keep the option to leave.

Sovereignty is not a location label. It is practical authority over infrastructure, data, models, operations and exit. We make those controls concrete—and produce the records needed to demonstrate them.

EU AI ACT / OPERATIONAL READINESS

We help create the technical evidence behind governance: traceable requests, model and version records, access enforcement, workload evaluations, operational logs and human-control points.
