AI intensive engineering
Datamentis was created to apply artificial intelligence at scale to the hardest defense problems, from local language models to operational analysis.
Datamentis develops advanced data intelligence and strategic decision-support systems for governments and critical organizations.
THE COMPANY
Built in France for missions that cannot depend on anyone else.
Datamentis is a French defense technology company building sovereign systems for government, armed forces and intelligence organizations. We turn advanced AI, secure architectures and mission knowledge into capabilities that can be owned and operated nationally.
Based in Paris, we work from strategic intent to deployed software: understanding the operational problem, engineering the system, securing its data and designing the interface used to act.
Datamentis was created to apply artificial intelligence at scale to the hardest defense problems, from local language models to operational analysis.
Our systems run on premise or on nationally controlled infrastructure, within the security and governance perimeter of the mission owner.
We connect data, models, secure software and human interfaces, from strategic command environments to augmented reality in the field.
WHAT WE ENABLE
We build the chain from collection to action: structuring big data in secure sovereign lakehouses, fusing heterogeneous sources, applying sovereign AI and delivering decision support to command and field teams.

Build sovereign, access-controlled lakehouse platforms for big-data workloads, then unify sensor feeds, databases, reports and open sources with full provenance.
Turn time, terrain, entities and events into a shared map that lets every authorized team work from the same reality.
Detect weak signals, model possible developments and surface the decisions that matter before the operational window closes.
Deploy advanced models inside the national security perimeter, adapted to mission data and operated without external inference services.
Monitor critical systems, correlate physical and digital indicators, and help operators identify anomalies before they become disruption.
Extend trusted information to the tactical edge through mission applications and AR interfaces designed for soldiers and field operators.
OUR FIRST PRODUCT
Citadel is a sovereign Data-Centric Security platform providing a ready-to-deploy control plane for policy, trust and cryptographic enforcement. Data is protected at object level without rebuilding every DCS component independently.
Three direct paths for the work operators perform most.

Classification metadata, integrity controls and optional encryption remain bound to each file or record wherever it moves.
Citadel checks identity, clearance, object integrity and national policy before content or cryptographic keys are released.
Policy, trust anchors, identities, clearances, key custody and audit remain under national authority on national infrastructure.
National teams configure what must remain national: policy, identities, clearances, trust and keys. Citadel supplies the security architecture and enforcement chain.
Run the sovereign Citadel node on national infrastructure.
Express classifications, handling rules and release policy.
Link identity, clearances, key custody and existing data stores.
Apply DCS controls to files, records and trusted exchanges.
Citadel provides the technical foundation for DCS compliance. Accreditation and operational governance remain national responsibilities.
OUR FOUNDATION

Datamentis is French by origin and guided by European values. Strategic autonomy requires more than hosting data nearby. It requires control of the software, the models, the infrastructure and the choices that determine how a mission system evolves.
Critical capabilities are understood, controlled and maintained at source level. The mission owner is never trapped behind an opaque dependency.
Systems, models and sensitive data can remain on premise or within approved national hosting, under local operational authority.
Core missions continue without foreign cloud services, external inference endpoints or another country controlling the technical roadmap.
BUILDING FOR THE CRITICAL
We work with institutions and mission-driven organizations facing complex, high-consequence challenges.
