The KICs carry out activities that cover the entire innovation chain: training and education programmes, reinforcing the journey from research to market, innovation projects, business incubators and accelerators. Through the KICs, the European Institute of Innovation and Technology (EIT) strengthens cooperation among businesses (including SMEs), higher education institutions and research organisations, forms dynamic pan-European partnerships, and creates favourable environments in which creative thought processes and innovations can flourish.
