“At Onecub, we’re convinced Europe’s Digital Single Market will be powered by data spaces: federated, self-governed ecosystems where organisations can share personal and non-personal data while retaining full control—securely, compliantly, and across borders.

Our mission is to make this future-proof “network of networks” a reality—and, in doing so, enable trustworthy, sovereign AI. Since 2011, we’ve helped hundreds of public and private organisations move from blueprint to scalable, AI-ready data sharing.“

Olivier Dion - CEO Onecub
