Become a member of Clean
As a member of Clean, you gain access to a strong network and up-to-date knowledge in the fields of water and the environment. We develop activities based on our members’ needs, and through our partnerships with public organizations, utilities, industry associations, and research institutions, we open doors for your company’s growth and innovation.
What are the benefits of
being part of a cluster?
Market access
Clusters shorten the path from innovation to market by connecting companies directly with customers, pilot partners, and value chain players.
Increased credibility
Being part of a recognized cluster builds trust among customers, investors, and public sector actors, and our data shows an average increase of +40% in the survival rate among cluster-affiliated startups.
Knowledge sharing
Clusters transform individual experiences into shared knowledge, and research shows that cluster-affiliated cleantech companies grow faster than those operating independently.
As member you will get:
- Concrete opportunities that can drive innovation and development within your organization.
- Access to a broad portfolio of collaborative projects.
- The chance to meet your next customer, supplier, or business partner.
- Unique knowledge and research that can drive innovation and growth.
- Access to international platforms that lay the groundwork for your international expansion and exports.
