Poseidona harvests invasive seaweed and algal side-streams and uses enzymatic hydrolysis and a proprietary combination of enzymes to extract high-quality proteins intended as a soy-protein alternative. The company's first product is a soy-alternative protein concentrate that currently has umami notes and a reddish color; the team is working on organoleptics to improve flavor and color. Founders Sònia Hurtado and María Cermeño combine industry experience—Cermeño holds a doctorate in food biochemistry and Hurtado previously co-founded Current Foods (acquired by Wicked Kitchen in 2023)—to advance R&D. Poseidona aims to launch the concentrate at the end of 2024. It plans to expand its proprietary methodology to other macroalgae species such as Sargassum and to develop regulatory-compliant collection programs involving fishermen as an additional revenue stream. The company says its goal is to achieve cost parity with mainstream plant proteins like soy and pea by using low- or null-cost side-stream materials.
