rrreefs association was founded in October 2020 and became a impact business in 2023. We offer reef regeneration services tailored to the needs of our clients. We work with reliable partners and local communities to ensure environmental and social impact for the regions we work in.
We are an interdisciplinary team with backgrounds in science, art, and economics. Our diverse skillsets allow us to approach challenges from multiple perspectives. Ulrike and Hanna make sure everything we do is supported by science. Marie is the creative problem-solver, making sure our reefs design is functional, stable, and nice to look at. Josephine makes sure we stay on track and focus on our company’s goals.
