ERRIN is a well-established Brussels-based platform of around 120 regional stakeholder organisations from 22 European countries, most of whom are represented by its Brussels offices. We focus solely on research and innovation policy and funding programmes, as well as project development. Our members are mainly regional authorities, universities, research organisations, chambers of commerce, and clusters. They develop the agenda and the priorities of the whole network by taking an active role within our working groups or in our Management Board. Through our 13 working groups, we work with research and innovation in a very comprehensive way, promoting triple and quadruple helix cooperation and the importance of regional innovation ecosystems. ERRIN facilitates regional collaboration and knowledge exchange to the benefit of all its members and partner organisations, with a view to build a competitive Europe which supports smart, sustainable, and inclusive growth in all regions.
