What Poseidona does
Poseidona (legal entity POSEIDONADA, S.L.) is a Barcelona-based foodtech startup founded in 2022 that produces sustainable protein ingredients from seaweed sidestreams (byproducts of the agar industry) and invasive algae. The company applies proprietary enzymatic processing technology, currently patent-pending, to convert low-value marine biomass into functional food ingredients including a clean-label gelling agent containing protein and fibre and a highly soluble protein hydrolysate, with a pipeline spanning texturized protein for meat alternatives and bioactive nutritional supplements. The technology is supported by R&D Lead Dr Gala Morena, co-inventor of two patents covering bioactive hydrogels and protein extraction from algae and author of 16 peer-reviewed publications.
The company operates a B2B ingredient supplier model, selling directly to food product manufacturers on a quote-based pricing basis and pursuing co-development partnerships as its primary go-to-market. Poseidona has established co-development engagements with a plant-based seafood company and a baked goods manufacturer, with additional exploratory conversations underway in pet food and sports nutrition; an IP licensing revenue stream for its processing methodology is also planned. Distribution is direct and global in scope, supplemented by participation in industry events such as Madrid Fusion and partnerships with food-tech ecosystem organizations.
Poseidona is female-led by CEO and founder Sònia Hurtado (former co-founder of Current Foods, YC20, with 25 years in the food industry), supported by CFO Rosalia Rubio and a six-person core team that includes a Scale Up Scientist (Robert Calvo) and a Commercial Applications Manager (Carolina Kyvik); co-founder María Cermeño serves as CSO. The company closed a €1.1 million seed round in March 2024 led by Faber with Dozen Investments, ProVeg International, Sprout & About Ventures, and WA4STEAM, and has secured non-dilutive support from EIT Food, Horizon Europe, Ship2B Foundation, Fondation Carasso, ENISA, ACCIO, and ICEX. It is registered at carrer Gaspar Fàbregas 81, Esplugues de Llobregat, Barcelona metropolitan area.
