Costa Yiannoulis, Synthesis Capital

About Costa Yiannoulis

Costa Yiannoulis, Managing Partner and co-founder of London-based Synthesis Capital, invests exclusively in upstream food technology and alternative proteins (plant-based, precision fermentation, cellular agriculture), focusing on pre-seed to Series A stages with a sweet spot of ~$1.5M and check sizes from $100K–$5M. His distinctive thesis targets companies developing scalable technology platforms and defensible IP upstream of end-products—such as feedstock engineering, bioreactors, and ingredients that improve taste/texture of alternative proteins—rather than conventional agriculture or restaurant tech. Notable portfolio companies include Savor (Series A, plant-based foods), Equinom (Series D, alternative protein ingredients), Geltor (Series B, precision fermentation), UPSIDE Foods (cultivated meat), Perfect Day (alternative dairy), and Hyfé (fermentation feedstocks from waste).
