Polarise launches sovereign AI cloud for European enterprises

A full-stack European cloud

German AI provider Polarise recently announced the launch of its sovereign AI cloud at the NVIDIA GTC Berlin event. This new platform is designed to provide enterprises with a way to use high-end artificial intelligence while ensuring that all data remains under their own control.

Unlike many cloud services that rely on third-party infrastructure, Polarise owns and operates every layer of its stack. This includes the physical data centers, the NVIDIA accelerated computing hardware, the cloud software, and the final applications that businesses use daily. Every part of this system is owned and operated by a European entity.

The company achieves this by using what it calls 'AI Factories.' These are its own data centers located in Germany and Norway. By owning the entire chain from the physical rack to the final API, Polarise ensures that customer data never leaves the European Union.

Rapid deployment with modular pods

One of the primary challenges in building new data centers is the long timeline required for permits and grid connections. Polarise addresses this by converting existing buildings that already have these requirements into functional hubs using modular AI Pods. These are small, self-contained data centers that can be installed and connected on-site.

This modular approach allowed the company to bring its Munich AI Hub from concept to operation in just 6 months. This is significantly faster than conventional projects, which often take years to complete. Because of this design, the Polarise AI Cloud can scale quickly to meet new customer demands as they arise.

The hardware powering these pods is built on the latest NVIDIA Blackwell platform. Polarise primarily relies on high-performance servers from its partner, Kerno, to provide the necessary computing power for its customers.

Tools for chatbots and developers

The launch includes two primary products: Polarise Rise and Polarise Drive. Polarise Rise is a chat assistant designed for corporate workspaces. It allows employees to collaborate on research, analysis, and writing while keeping company information on Polarise infrastructure in Europe. It is currently available through three different subscription models.

For developers, Polarise Drive offers managed inference for leading open-weight models. These are models where the weights—the internal parameters of the AI—are publicly available. Users can access models like GLM 5.3, Kimi K3, or the NVIDIA Nemotron via a single API without having to manage any underlying hardware.

Polarise Drive is compatible with the OpenAI SDK, meaning developers can switch to it by changing just one line of code. The company also plans to introduce an Agentic Engine for deploying custom AI agents and MCP support for tool integration in the future.

Compliance and data sovereignty

A major selling point for the Polarise AI Cloud is its commitment to data sovereignty. Because the infrastructure is entirely European, customer data is not exposed to the U.S. CLOUD Act, which can sometimes allow U.S. authorities to request data from American companies regardless of where that data is stored. This is a critical distinction for many European organizations.

The company is already certified to ISO/IEC 27001 and ISO 9001 standards. It is also currently preparing for BSI C5 and SOC 2 Type I and Type II attestations. These certifications help prove that the platform meets high security and operational standards.

The company is already seeing production use for these tools. For example, the Italian customer experience company Increso uses Polarise Drive to run AI agents for customer service. Marco Modonesi, CTO at Increso, noted that clients expect agents that are "fully compliant with European data protection rules."
