Innovation Networks for Active and Healthy Ageing (IN-4-AHA) is a EU-funded Coordination and Support Action (CSA) that contributes to the cross-border scale-up of tested and ready-to-use applications in health and social care. The project will bring together both the support and the demand sides as well as the end-users, engage with local and regional ecosystems, stakeholder groups and organisations. The main outcome of this cooperation is an innovation scale-up model that is validated by stakeholders and complemented by a clear implementation roadmap, an innovation impact evaluation toolkit and a strategy for long-term investments.
