Our unique technology and fully independent impact-based business model allows for scalable and cost-effective projects that can be deployed anywhere in the world. Most marine conservation projects depend on philanthropy and funds, which are often hard to find. This limits the impact of the projects enormously. For marine conservation to be meaningful and scalable, it needs to be financially independent. That’s why we created an impact-based business model that helps us make marine regeneration financially sustainable. Show less
