About

SeaGen (Seaweed Generation Ltd), based in Falmouth, UK and founded in 2021, builds AI-driven solar-powered marine robots β€” notably the AlgaRay, which scoops up invasive Sargassum seaweed and sinks it to ~200m depth for deep-ocean carbon sequestration, and the AlgaVator for automated seaweed cultivation. The company is venture-backed (Aera VC, Climate Capital, Remove, others), employs ~12-19 people, and has been actively piloting in the Caribbean while developing MRV and monitoring technologies.
