Corallia Clusters Initiative -or in short Corallia- is the first organisation established in Greece for the structured and systematic management and development of innovation clusters, with the strategic aim to develop cohesive and productive innovative ecosystems within which actors operate in a coordinated manner, in specific sectors and regions of the country, and where a competitive advantage and export orientation exists.

Innovation Clusters are "groupings of independent undertakings (innovative start-ups, small, medium and large undertakings as well as research organizations), operating in a particular sector and region and designed to stimulate innovative activity by promoting intensive interactions, sharing of facilities and exchange of knowledge & expertise and by contributing effectively to technology transfer, networking and information dissemination among the undertakings in the cluster".
Nano/Microelectronics based Systems and Applications Cluster (mi-Cluster), is the first innovation cluster in Greece and since its establishment in 2006, it demonstrates a continuous development. Today, the mi-Cluster consists of more than 130 members including innovative start-ups, small, medium and large companies, academic labs and research institutes, science parks, networks, associations, suppliers of services, financial institutions, media of different kinds, national ministries and regional agencies involved in industry, regional, science and technology development and policy, from all over Greece.
