The HORIZON-CL4-2025-03-DATA-13 call, under the Horizon Europe programme and the European Partnership on AI, Data and Robotics, invites innovation action proposals to strengthen compliant and competitive data ecosystems across the EU. The initiative supports organisations facing growing regulatory complexity under EU legislation such as the GDPR, AI Act, Data Act, and Green Deal.

Proposals should focus on one or more of the following key areas:

1. Advanced compliance technologies – including AI-powered tools for interpreting and operationalising legal texts, natural language processing (NLP), privacy-preserving mechanisms, and intelligent systems for predicting compliance risks and monitoring regulatory changes.
2. Auto-compliance in data spaces – developing semi-automated or fully automated mechanisms that ensure data transaction compliance with EU and sector-specific rules, tailored to the governance and architecture of Common European Data Spaces, and in alignment with the Data Spaces Support Centre (DSSC).
3. Synthetic data generation and validation – using generative models and simulation-based approaches to overcome real-world data limitations (e.g. bias, availability, confidentiality), and ensuring the fitness for purpose, safety, and ethical use of synthetic data through robust evaluation and benchmarking protocols.

Expected outcomes include:

• reduced administrative burdens and streamlined compliance for businesses and professionals;
• enhanced use of synthetic data to improve quality, diversity, and accessibility;
• broad uptake of compliance-by-design and FAIR principles;
• scalable training and support programmes to meet evolving user and sectoral needs.

Proposals must include comprehensive user needs analysis, training plans, and impact indicators, and are encouraged to address cybersecurity, interoperability, and standardisation. Collaboration with existing initiatives such as the Digital Europe Programme, the AI-on-Demand Platform, and simulation/digital twin projects is highly encouraged.

The call is open until 02 October 2025 at 17:00 Brussels time and follows a single-stage submission model. Projects will be funded as innovation actions through Horizon Europe lump sum grants.
