Macro Oceans

Macro Oceans is a California-based seaweed biotechnology company that cultivates, processes, and transforms 100% traceable kelp into marine bioactives and biomaterials for beauty, food, and materials applications. Founded in 2020, the company operates a proprietary seaweed bioprocessing facility in West Sacramento and works closely with kelp growers, ingredient brands, and technology partners to build a robust, traceable seaweed supply chain. Macro Oceans positions kelp as a high-impact, low-carbon alternative to petroleum-based chemicals and strained agricultural feedstocks, targeting the beauty, nutrition, and materials sectors. The company has raised $7.5 million in seed funding from investors including Refactor Capital, Lowercarbon Capital, and McKinley Capital.
