Phykos

Phykos, formerly known as PBC, operates from San Francisco, CA, with a fully remote team of two. As a participant in Y-Combinator’s S21 batch, the company focuses on climate stabilization through the cultivation of seaweed. Phykos specializes in a nature-based carbon removal process that not only removes excess atmospheric CO2 but also benefits the ocean by cleaning, cooling, and de-acidifying its waters. The company utilizes robotic platforms for seaweed growth that are designed to optimize growth while avoiding ecologically sensitive marine areas. Their process involves cultivating seaweed and sinking it to depths greater than 1500 meters, ensuring durable carbon sequestration that is safe for over 1,000 years. Phykos sells carbon offsets, aiding organizations in meeting their climate commitments, and plans to open its sales pipeline for these seaweed carbon offset products in 2023 through a network of trusted brokers. As a Public Benefit Corporation, Phykos amplifies natural marine carbon cycles, targeting significant scale impact on climate change.
