About David Helgason

David Helgason is an Icelandic angel investor and climate-focused partner at Transition.vc, best known as the co-founder and former CEO of Unity Software, which he led from its 2003 founding until October 2014. His investment thesis centers on early-stage climate technology, with additional activity in edtech, software, gaming, and AI across Europe and the Nordic region.
