At Circular Berlin, there are two main types of members: community members, and team members. The latter also has two sub-categories: Core and Experts. At Circular Berlin, we get together to work on projects which are aligned with our organization's vision. We pool a diverse mix of people, depending on the project. These can include strategists, experts with deep knowledge on a topic, researchers, and design and communication support. We might also partner with a third party if it makes sense. We engage with Circular Berlin on a voluntary basis, and at times on a (paid) freelance basis.
