EcoSea is a food-tech company in the aquaculture sector that utilizes its proprietary solution to produce high-quality protein in locations where it has not been possible before: sites that are not protected from bad weather, high waves, active currents, hurricanes, typhoons, etc. (High Energy / Offshore Sites). EcoSea is able to harvest the untapped potential of the ocean to fill up the world’s protein gap by increasing the usable water for fish production in a sustainable way. Our company was born in Chile in the epicenter of one of the largest aquaculture clusters in the world, conducting R&D and validation efforts for more than a decade in four continents and now is poised to improve the global protein production from the ocean by targeting key markets such as the Asia Pacific, North American and European regions.
