Granite Infrastructure
Granite Infrastructure is building the Agentic Cloud, a fully integrated, open-source stack spanning bare-metal servers, GPU fabric, storage, encrypted networking, AI runtime, and orchestration. The platform is deployed on customer-owned infrastructure with keys held exclusively by the customer, enabling sovereign AI deployments for European enterprises. It claims up to 70% lower costs than conventional cloud rental models while maintaining a 99.99% availability SLA.

Problem
Organizations seeking to deploy agentic AI workloads face a stark trade-off between cost efficiency and data sovereignty. Renting cloud infrastructure from foreign providers undermines control over sensitive data and the AI stack itself, while fragmented, multi-vendor solutions introduce compliance complexity and operational overhead. This forces enterprises to choose between relinquishing ownership of their AI infrastructure or paying premiums for customized, sovereign deployments.
Solution
Granite solves this by delivering a complete, integrated agentic cloud stack—compute, storage, GPU, agents, and audit—that customers deploy on their own infrastructure and own outright. The platform is open source end to end and purpose-built for European deployment, ensuring full compliance with regional data regulations. Granite integrates six layers into one platform: bare-metal servers, GPU fabric with an AI broker, content-addressed storage, an encrypted mesh network with built-in VPN, model-agnostic AI runtime, and a unified inference endpoint that routes prompts to the best model at the best price. This architecture enables stronger utilization economics, yielding up to 70% lower costs compared to conventional cloud rental models, while maintaining a 99.99% availability SLA through a distributed fabric with no single point of failure.
Target Audience
Primary customers are European enterprises, public-sector organizations, and AI-native companies that require sovereign, fully owned AI infrastructure for sensitive workloads and regulatory compliance.
Features
- Quantum-safe storage that can be mounted directly under compute slices or exposed via WebDAV/S3 protocols, with content-addressed filesystem and Redis-compatible object storage
- Mycelium OS providing an encrypted mesh network connecting all nodes privately, with integrated VPN functionality and no external side door
- Hardware-agnostic stack with no single-vendor lock-in, running on the hardware that fits the workload and changing as workloads evolve
- Modular data centres deployable beside available energy, enabling capacity to go live without waiting years for new grid connections
- Model-agnostic runtime allowing deployment of any open-source AI model while retaining full ownership
- Unified inference endpoint that intelligently routes each prompt to the optimal model based on performance and price
- Full-stack integration from silicon to agent orchestration, eliminating multi-vendor fragmentation
- Open-source architecture guaranteeing transparency and auditability across every layer
