GAEA project successfully implemented its acceleration phase, providing participating teams with structured workshops, mentoring, and practical guidance to transform early-stage ideas into market-ready solutions. A total of 24 business acceleration modules were delivered, covering key areas such as product feasibility, financial modeling, legal and corporate structuring, operational planning, branding, and marketing strategy. This comprehensive approach enabled 15 teams, comprising 55 students, to strengthen their entrepreneurial skills, refine their business models, and achieve investment readiness. The acceleration activities culminated in two Demo Days, held on 25 July 2025 and 10 December 2025, where teams presented their solutions to investors, strategic partners, and early adopters. These events allowed participants to test their value propositions, receive structured feedback, and establish connections with the European innovation ecosystem. Complementing this, the final GAEA Workshop brought together startups, students, industry representatives, policymakers, and EU stakeholders for eight knowledge- and idea-sharing sessions, consolidating project outcomes and fostering cross-regional collaboration. As a tangible outcome of these efforts, five startups were formally established, each legally incorporated and positioned for engagement in the European market. In total, 40 MVPs were developed, reflecting the effectiveness of the structured training, mentoring, and interregional collaboration provided by the project. The scientific and technical impact includes the validation of acceleration methodologies, open innovation practices, and interregional knowledge-sharing approaches, supported by the IMS platform to track progress and ensure reproducibility of results. These outcomes provide a strong foundation for commercialization, market uptake, and further international scaling of the innovations, while fostering a robust, inclusive, and collaborative European green innovation ecosystem.
