## About

Panthalassa, based in the US, pioneers a planetary-scale energy platform focusing on innovative and sustainable clean energy solutions to address global energy demands. Founded in 2016 by Garth Sheldon-Coulson and Brian Moffat and headquartered in Oregon, US, Panthalassa is dedicated to developing a clean energy platform. The company has not reported any pivots in its business strategy. In August 2026, Panthalassa raised an undisclosed amount of venture funding from new investor Naver. Their offerings focus on clean energy generation and infrastructure that can be rapidly deployed and scaled, particularly targeting coastal and offshore regions. By leveraging advancements from aerospace, naval architecture, and software engineering, Panthalassa serves a diverse clientele, including governments and industries seeking sustainable energy alternatives. They are actively conducting pilot projects, including their Pacific Ocean initiative, to validate their solutions.Panthalassa operates under a business model centered on partnerships and direct B2B transactions with clients requiring renewable energy solutions. Revenue generation occurs through collaborative agreements with organizations integrating their energy platform into existing infrastructures. Specific pricing models are undisclosed; however, revenue is likely facilitated through long-term contracts or subscription agreements for energy supply and technology access related to their proprietary technologies for energy management. The company will use the August 2026 funding to accelerate the development of floating, wave-powered artificial intelligence data centers and offshore computing infrastructure.
