Membership is open to private industrial companies with an interest to develop activities in Europe. It is also open to Research & Technology Organisations (RTOs), universities (or university departments), national/regional clusters, port and territorial development agencies, private investors or NGOs who are based in Europe. Sectorial/trade associations at European or national level, policy makers and governmental agencies cannot become members.
