Substrate AI

Substrate AI builds Europe's sovereign AI foundation: a full-stack cloud and compute platform enabling enterprises, governments and research organisations to run large-scale AI workloads under European jurisdiction. Our mission: deliver high-performance, compliant AI infrastructure "built in Europe, for Europe & the World." Platform Architecture Substrate AI is delivered in three integrated layers: 1. Substrate Cloud AI-optimised managed cloud with bare-metal and Kubernetes orchestration, on-demand GPUs across global regions, GDPR-compliant environment for AI training and inference, and dedicated European cloud regions for data sovereignty. 2. AI Factories High-density, liquid-cooled data centers powering next-generation Nvidia GPUs, engineered for large-scale AI training and inference. 3. Serenity Star An agentic intelligence layer for compliant enterprise copilots, retrieval-augmented systems and AI assistants. Deployable on Substrate Cloud, creating an end-to-end stack from compute to intelligent agents. Core Principles • European data residency via dedicated EU cloud regions ensuring GDPR and regulatory alignment • High-performance NVIDIA compute (H100, H200, B200, B300 & next-gen) optimised for large-scale training and inference • InfiniBand and high-power rack design for low-latency, high-throughput AI workloads • Sustainable infrastructure powered by renewable energy with heat reuse and carbon-capture Target Sectors Substrate AI serves healthcare, finance, public sector, manufacturing, gaming and smart cities. Use cases include LLM training, inference, RAG, federated research and mission-critical AI operations. Who We Serve For organisations prioritising data sovereignty, auditability and AI performance within EU jurisdiction, Substrate offers turn-key deployments, dedicated clusters and hybrid integration to modernise MLOps while maintaining control and compliance.

Hilt

Hilt deploys kernel-level sensors across your cloud, endpoints, and network to observe every data movement as it happens. When behavior deviates from learned baselines even through valid credentials and authorized channels, we detect and contain it in under a second.
