Algaeo makes hardware that allows farmers to grow sustainable, efficient, and organic fertilizers on-site using micro-algae and artificial intelligence. The company’s technology leverages adsorption to efficiently pull carbon dioxide and nitrogen from the atmosphere to feed algae. Algaeo uses three nontoxic algal strains, which benefit soil health and boost plant growth by providing nutrients to capture carbon from the atmosphere. Algaeo reduces farmer costs for fertilizer, improves yield and quality, and improves soil health for future growing seasons. Algaeo is part of the 2024 Innovation Crossroads cohort.
