The overall objective of the project is to unlock the untapped potentials of social innovations (SIs) to boost the EU Missions by promoting, activating, scaling and mainstreaming SIs and by engaging and advising SI funders, investors, social innovators and R&I policymakers at European, national and local level through a series of interconnected measures. To attain this objective, we will address four Key Actions: 1. Identify an evidence base of successful and - regarding the EU Missions - auspicious SIs and co-create suitable impact pathways and anchor points for the integration of SIs in future calls and topics of the EU Missions. 2. Provide training and advice through our Training and Scaling Lab about the opportunities provided by the EU Missions, by upgrading the skills of social innovators and support organisations for successful scaling and participation in calls of the EU and of private and public funders dealing with mission related themes. 3. Create a SI Funding and Investors’ Network to advise and engage private and public funding authorities in supporting, financing and scaling powerful SIs for the EU Missions’ purposes and by expanding the range of financial instruments with the help of a SI Investment Lab. 4. Establish a Community of Practice (CoP) to implement regular exchange and learning between EU Missions, the SI Funders and Investors’ Network and social innovators to meet demand and supply and to co-create a Research Agenda to make the best use of SI for the EU Missions. The Key Exploitable Results (KERs) of the project are a Catalogue of SI impact pathways (KER-1); Operational Training and Scaling Lab (KER-2); 30 credible scaling plans (KER-3); a committed funding network to support EU Missions established (KER-4); one financial Framework Partnership Agreement for a networked catalytic fund prepared (KER-5); A co-designed research agenda (KER-6) and >200 organisations engage in exchange and dialogue (KER-6).
