Europe’s Sovereign AI Cloud & Compute Infrastructure
Secure | Sovereign | Scalable | SustainableSubstrate AI builds the sovereign foundation for artificial intelligence combining high-density
AI infrastructure powered by NVIDIA’s latest AI compute architectures, multi-region cloud services,
and next-generation AI factories that allow enterprises, governments, and innovators to deploy
AI securely, sustainably, and at scale within European jurisdiction.
Our partners
A new era of European AI sovereignty
Artificial Intelligence is the new electricity and sovereignty is the new infrastructure.
Across Europe, organizations need compute power that protects their data, respects regulation, and enables innovation without dependency on foreign hyperscalers.
Substrate AI bridges that gap. We operate sovereign AI infrastructure powered by NVIDIA’s latest AI compute architectures from Spain, expand across EU regions for performance and resilience, and deliver a full AI lifecycle platform from raw compute to intelligent agents.
Our mission is simple:
“Make AI infrastructure as sovereign as energy 100% European, high-performance, and compliant by design.”

Our platform
Three layers of AI sovereignty

Substrate Cloud
A full-stack sovereign AI cloud delivering AI-optimized compute powered by NVIDIA’s H100, H200, and next-generation Blackwell, GB200, and Rubin architectures, compute, storage, and networking under EU governance. Operate workloads across EU regions with enterprise-grade orchestration and hybrid integration.

AI Factories
High-density data centers engineered for training, fine-tuning, and inference liquid-cooled, energy-efficient, and ready for next-gen architectures (Blackwell, Rubin, GB200). Deploy dedicated or co-developed sovereign clusters with guaranteed availability.

Serenity Star
The intelligence layer an agentic AI platform for enterprises and governments to build compliant copilots, RAG systems, and digital assistants powered by Substrate’s infrastructure. Together, they form Europe’s most complete sovereign AI stack, where compute, models, and governance work as one.
Why Europe Chooses Substrate
Sovereign
by design
All workloads processed under EU jurisdiction; compliant with GDPR, ENS, and the AI Act.
Performance
without compromise
>100 kW per rack, InfiniBand networking, and AI clusters optimized for large-scale model training and inference purpose-built for AI workloads.
Integrated
stack
AI-optimized compute powered by NVIDIA’s H100, H200, and next-generation Blackwell, GB200, and Rubin architectures, Kubernetes, storage, and networking through one unified platform and API.
Sustainable infrastructure
Renewable power, heat reuse, and Orbital carbon-capture chillers.
Trusted Ecosystem
NVIDIA, Lenovo, Dell, WEKA, Vast Data, Vodafone, Orbital Materials, and more.
