Poseidona, founded in 2022, is a Spanish food tech company that develops alternative proteins from algal sidestreams and invasive seaweeds. According to the company, its production method consumes less water and land and emits less carbon emissions than animal-based or conventional plant-based proteins.
Poseidona currently uses side streams from "gellifier" production and plans on integrating Rugulopterix Okamurae, an invasive Mediterranean seaweed, into its production process in the future.
Funding and financials
In March 2024, Poseidona raised EUR 1.1 million (~USD 1.2 million) in pre-seed funding led by Faber, with participation from Dozen Investments, Sprout & About, Proveg International, and WA4STEAM. The funding was earmarked for expediting R&D and commercializing its protein ingredients.
