The Data Marketplace is a proof-of-concept platform designed to demonstrate how data creators, collectors, and consumers can interact within a secure, compliant, and monetizable ecosystem. It tackles key industry challenges such as data fragmentation, regulatory complexity, and untapped monetization potential—especially in light of the EU Data Act. This activity was presented and kicked off at the last AMM. In this session, we’ll report on the progress of the initiative and showcase major use cases live through our prototype. Whether you're working on data platforms, identity systems, fleet services, or regulatory tech, this talk offers practical insights and technical inspiration. We welcome your feedback and ideas to help shape the next phase of this open collaboration.
