Social entrepreneurship has been identified as a key feature of the EU social market economy, social enterprises (SEs) contributes to the emergence and expansion of new market-based business models seeking ways to contribute to economic and societal values. SEs also have great potential for developing social innovations to improve quality of life, satisfy new needs, or public sector restructuring. Nonetheless, the concepts of “social economy” and “social innovation” are little known or misunderstood and it seems to be considered rarely as an important factor for business, especially for young people. On the other hand social start-ups encounter more difficulties in reaching the economic sustainability.The project INN@SE rely on the idea that a successful approach to overcome such challenges, can be represented by the open innovation methodology based on a cross-sectoral collaborative process. Thus, the project partnership is created by organizations from countries with different level of know-how on SE (Poland, Italy, North Macedonia, Jordan), representing sectors with different approaches to the topic (higher education, research, NGO). All partners are highly specialized in activities related to young people empowerment, training, social economy research, and start-ups development and the diverse knowledge, experience and skills that each partner imputes to the project, should be valued and recognized as essential to ensure the success and sustainability of the joint efforts.Taking context and needs into consideration, partners have identified the following objectives which derive directly from the 3 target needs areas (skills & capacity building, orienteering & networking, awareness raising):1. To disseminate entrepreneurial mindset and skills among young people at a broader EU level; to provide aspiring young social entrepreneurs with a clear toolkit to start up; 2. To facilitate access of young people and youth staff to information regarding grant, training and mentoring opportunities and tools at local and international level; to promote networking among young SEs; 3. To promote an EU culture of SE among society, rehabilitating entrepreneurship through social entrepreneurship, with a special attention to the contribution represented “by” and “to” young people; to raise awareness among young people as active citizens regarding social, environmental, and diversity challenges of EU communities, and how SE can face them; to promote the visibility among key stakeholders of social businesses and the importance of social innovation and social impact.Target groups to be addressed:- young people (18-35), especially running/involved in SEs or with an interest in doing so – 280 participants directly involved in project activities;- youth workers, trainers, teachers, business coaches and other professionals (and related organizations) supporting and promoting entrepreneurship among young people, relevant stakeholders – at least 70 participants directly involved in project activities.Through a 3 project phases (preparation – implementation – exploitation), the partners will elaborate a joint innovative methodology based on the transfer of the open innovation and co-design approach. 4 intellectual outputs linked to 3 main need areas will be created:1. Inn@SE Youth SE Research Study - a multi-sided analysis in the field of youth SE to define the model of supporting SE of young people, spot weaknesses and strong points and design a training scheme both in the field of training for social entrepreneurs already working and for others who will like to develop their professional careers in this sector.2. INN@SE Youth SE Educational Game – to provide young people with innovative and attractive way to learn about social entrepreneurship.3. INN@SE Young People Training Program & Toolkit - to provide aspiring young social entrepreneurs with a clear and flexible toolkit to start up, with a particular attention to the financial sustainability topic.4. Inn@SE Services for Youth SE - innovative youth SE services and policy recommendation developed through service co-design and design thinking methodologies to better empower and support young social entrepreneurs.Moreover, 3 multiplier events (“Innovathons” which follow the hackathon methodology) will be organized to disseminate project results, promote their exploitation and involve young people at local level.The ultimate purposes or the expected impacts of the project are to contribute to strengthening the offer to enhance professional skills of young people and to promote effectiveness and innovation in the SE development.Holistic approach and multi-sided analysis will ensure the transnational applicability and relatively easy transferability. All materials and training tools will be available on an open source platform, in order to reach the maximum results in terms of visibility, dissemination and access to any indirect beneficiary interested in youth SE.
