Sovereign AI Infrastructure

AI that belongs to the institution running it.

Congruence builds open R&D infrastructure for the EU AI ecosystem and production-grade sovereign systems for regulated industries, where AI must be certified, auditable, and independently controlled.

Thesis

Most organizations will never own their AI. That is a structural problem.

Congruence exists to close that gap. Not with another cloud-inference wrapper, but with a vertically-integrated stack that runs inside the institution's own perimeter. Compute, retrieval, reasoning, audit. One architecture. Two lines of output.

The Architecture

Two distinct lines. One foundation.

R&D Line Open · IPCEI AI

Open research primitives for the European AI ecosystem.

Foundational R&D contributions developed under IPCEI AI, solving the hard infrastructure problems of sovereign, certified, and federated AI deployment. Released as open-source building blocks.

Commercial Line Live · Production

Production sovereign AI systems for regulated industries.

Purpose-built AI systems regulated institutions deploy on infrastructure they control. Framework-agnostic by design, extending to every sector where AI must be certified and owned.

Research & Development

Open primitives. One ecosystem.

R01 · Open source
01

Federated Retrieval

Cross-border retrieval across Member State regulatory corpora without exposing source documents.

R02 · Federated
02

Sovereign Model Architecture

Federated training across IPCEI partners. Each institution contributes locally, the combined model serves any domain.

R03 · Infrastructure
03

Inference Acceleration

Significant inference speedup on sovereign European hardware. Latency parity without hyperscalers.

R04 · EU AI Act
04

Certified Uncertainty

Provable coverage guarantees for AI systems operating under EU AI Act requirements.

R05 · Certifiable
05

Neurosymbolic Reasoning

EU regulation as machine-verifiable rules. Certifiable reasoning traces, not just answers.

EU AI Continent Agenda

Built for the moment Europe is building for.

Associated Partner

A contributor, not a beneficiary.

Congruence participates as an associated partner, contributing R&D work packages with demonstrable spillover across Member States and regulated sectors.

2026
II
EU AI Act
First Mover

Fully enforceable in 2026.

Every high-risk AI system in Europe needs conformity assessment. Congruence is building the missing compliance layer, released as open source.

Article 15

Sovereign AI Factory
Croatia

Sovereign GPU infrastructure.

Federated learning aggregation on auditable sovereign hardware. Physical infrastructure that makes European AI sovereignty operational, not theoretical.
