Panthalassa designs and operates autonomous floating nodes that generate electricity from ocean waves for onboard use. Founded in 2016 by Garth Sheldon-Coulson and Brian Moffat, the company's core product is a solid-state spherical node approximately 50 meters in diameter with a 60–70 meter subsurface neck; as waves move the structure vertically, water is forced into a pressurized internal reservoir and flows through a turbine to produce continuous power. The technology targets two primary markets: clean hydrogen production for maritime transport and offshore data center operations, with compute hardware running AI workloads via LEO satellite connectivity. Panthalassa is headquartered in Portland, Oregon. The company is structured as a public-benefit corporation and has attracted technical talent from NASA, SpaceX, and the U.S. Air Force. Specific details on recent funding rounds, lead investors, and current executive team members beyond the founders are not publicly documented in available sources.
