The document discusses the role of data incubators in shaping European Data Spaces. It describes the European Data Incubator (EDI) project which incubated over 100 startups and SMEs working with data from 30 providers over 3 rounds. EDI helped broker data sharing agreements and connect companies to investors. The REACH incubator builds on EDI's work, facilitating cross-sector experimentation through an 11-month program involving startups, large corporations, and Digital Innovation Hubs to develop trusted and secure data solutions. REACH aims to demonstrate how data silos can be broken by enabling multi-stakeholder collaboration across industries.
