Corallia is the first organisation established in Greece for the structured and systematic management and development of innovation clusters, in specific sectors and regions of the country, aiming at boosting competitiveness, entrepreneurship and innovation, in knowledge-intensive and exports-oriented technology segments, where Greece has the capacity to build a sustainable innovation ecosystem. To date, 3 highly-specialised clusters have been developed in knowledge-intensive thematic sectors with a strong exports-orientation: the mi-Cluster (nano/microelectronics-based systems and applications), the si-Cluster (space technologies and applications) and the gi-Cluster (gaming technologies and creative content). Corallia promotes the hyper-concentration of industrial members of clusters in the InnoHubs to boost innovation. It currently operates three InnoHubs, in Athens and in Patras: the α1•innohub established as the innovation and cutting-edge technology node in Maroussi, Athens, the π1•innohub operationg as the innovation, research and high-tech bridge in Patras, and the α2•innohub (HQ) positioned as the innovation, networking and high-tech ring in Maroussi, Athens. Additionally, Corallia implements a series of initiatives to stimulate and promote Youth Entrepreneurship, in collaboration with high-profile partners and supporters and organizes programmes including the most prominent accelerator programme currently in Greece, the egg–enter.grow.go, in cooperation with Eurobank. It is also responsible for Educational Trip, co-organized with the student associations from Stanford, Berkeley, MIT and Georgia Tech. Aiming at achieving key-strategic International Collaborations, Corallia demonstrates a strong engagement in European cluster policy bodies cooperating with all innovation stakeholders, regional and national development offices around the world with the ultimate goal to ensure a strong impact on cluster development in the participating countries and beyond.
