Bull, a state-owned French maker of Europe's fastest supercomputers, and Schwarz Digits, the technology arm of Schwarz Group, signed a preliminary agreement to jointly develop AI computing services. Schwarz Digits will offer the service through its STACKIT cloud business, which rents out computing power and data storage over the internet.
Why it matters
The deal pairs European-made supercomputing hardware with a European cloud provider, aiming to give companies and public bodies an alternative to foreign-controlled AI infrastructure. Financial terms were not disclosed.
The agreement is a preliminary, non-binding-stage arrangement with no disclosed financial value, while Bull's plant output doubled in October 2026. Financial terms and launch timing remain unannounced.
