Flower SuperGrid federated AI platform

Flower Labs GmbH is a company with its legal address in Hamburg, Germany, that builds open software for federated and collaborative AI. It describes itself as a team of AI researchers and engineers, and its Flower framework lets organizations train and analyse models across data that stays on-site.

Flower SuperGrid, announced in preview in September 2025, is a federated AI platform where data owners connect SuperNodes to form a federation and then launch Flower apps. It targets regulated sectors such as healthcare and finance as well as telecom and energy. The company also offers Flower Hub, Flower Agent and Flower Models, and reports ISO 27001 compliance since March 2025.

• SuperGrid federations: connect SuperNodes to form a federation and launch apps.
• Flower framework: open-source federated learning with frequent releases.
• Flower Hub: app hub for collaborative AI launched in March 2026.
• Federated analytics and datasets: tools for federated data work.
• Confidential computing: listed as a preview capability for SuperGrid.
• Flower Models and Agent: sovereign AI models and a collaborative agent.

• Vietnamese hospital groups training diagnostic models across sites without sharing patient records.
• Banks building fraud models jointly across institutions while data stays in each bank.
• Telecom and energy operators training models on edge data that must stay on premises.

• Models can be trained across organizations without centralizing sensitive data.
• Data owners add or remove SuperNodes and allow-list users without manual configuration.
• Open software with a large developer community and weekly releases.
• ISO 27001 compliance announced in March 2025.

Regulated industries and public bodies want to train AI on data that cannot leave its owner, which makes federated learning a growing approach, with health services and banks among the organizations shown on the site. Vietnamese hospitals, banks and telecom operators holding siloed data face the same constraint.
