K Ren designs and manufactures submerged textile hull covers intended to limit biofouling by preventing photosynthesis and the growth of microorganisms, avoiding the diffusion of biocides. Founded in 2020 and based in Mauguio (Hérault), the company produces its covers in France from domestically sourced materials. K Ren targets boats that remain long at berth and those sensitive to hull performance, and it highlights fuel- and performance-related benefits from cleaner hulls. The company plans to use the €1.2M raised to industrialise production and scale commercial deployment. Its fundraising included institutional and angel investors as well as a participative campaign that collected over €120,000 from existing users, including noted sailors who have tested the product.
