Kelp Blue is an environmental services company founded in 2020 that specializes in regenerative ocean farming. The company cultivates large-scale Giant Kelp (Macrocystis pyrifera) forests on offshore structures, a process designed to sequester carbon and restore marine ecosystems. By managing these underwater forests, Kelp Blue harvests seaweed to produce sustainable, bio-based products for agriculture, pharmaceuticals, and other industries. Their approach integrates ocean science with large-scale cultivation to address global climate and sustainability challenges.

The company's primary product, StimBlue+, is a seaweed-based biostimulant that improves soil health, enhances crop resilience to abiotic stress, and can increase yields for a variety of crops, including maize, tomatoes, and grapes. By offering farmers an alternative to synthetic inputs, Kelp Blue helps reduce chemical dependency and supports more sustainable agricultural practices. To scale its operations, the company partners with logistics firms to build integrated supply chains that move biomass from its coastal production sites to both domestic and international markets.
