The Essentials
Bull and Schwarz Digits aim to jointly develop a European cloud and computing offering for artificial intelligence. Their preliminary framework agreement envisions combining STACKIT’s cloud infrastructure, operated by Schwarz Digits, with Bull’s expertise in AI servers and high-performance computing. At this stage, no definitive commercial commitment or financial terms have been announced.
- A combined offering: the STACKIT marketplace would host the BullSequana AI platform to provide European AI solutions and software within a modular cloud environment.
- Industrial capacity: Bull intends to draw on its Angers plant and its liquid cooling know-how to produce AI servers at rack scale.
- Planned developments: the two partners also envisage servers built on Open Compute Project standards, high-performance computing, and the integration of SAP RISE.
- Target sectors: the alliance is particularly aimed at companies and administrations subject to strong sovereignty, data localization, and regulatory compliance requirements.
Bull and Schwarz Digits, the IT and digital division of Schwarz Group (owner of Lidl), intend to build an independent European AI and cloud ecosystem.
While the signed document is a preliminary framework agreement that at this stage does not include financial terms or a definitive commercial commitment, the intention to jointly develop AI computing services in Europe is real.
The cooperation rests on balanced complementarity. Schwarz Digits would provide the cloud infrastructure via STACKIT, while Bull would bring its expertise in artificial intelligence and high-performance computing.
STACKIT as the Cloud Foundation
Launched in 2018 to meet Schwarz’s needs, STACKIT now offers IaaS, PaaS, and SaaS services to European businesses and public administrations.
The platform runs data centers in Germany and Austria. It emphasizes GDPR compliance and carries several security certifications, including ISO/IEC 27001, ISO 27017, ISO 27018, ISO 20000, and BSI C5 Type 2.
Under this partnership, the STACKIT marketplace would integrate the BullSequana AI platform. Customers would thus gain access to AI solutions and European software in a modular environment, without relying on a non-European operator.
Bull aims to mobilize its European industrial capabilities, notably its Angers plant, to produce AI servers at rack scale. The group also highlights its experience with liquid cooling using warm water and large-scale AI deployments.
The two companies also plan to jointly design servers based on Open Compute Project standards. Beyond AI, they mention high-performance computing, the SAP RISE integration, and exploration of quantum computing.
Bull Bets on Angers and Liquid Cooling
The partnership is primarily aimed at strategic and regulated sectors, where data localization, infrastructure control, and regulatory compliance weigh heavily in technology choices.
This strategic direction seems to be paying off. STACKIT has been selected for the multicloud portfolio of GovTech Deutschland’s “Deutschlandplattform,” a framework that can reach up to €250 million dedicated to German administrations. The provider has also signed a framework agreement with the Dutch Ministry of Justice and Security to become an official cloud alternative for certain public agencies.
In early November, the company also launched RISE with SAP on STACKIT, with the technical deployment slated to begin in November 2026.
