Investment thesis
Silicon Roundabout Ventures is a London-based pre-seed and seed fund investing in European deeptech founders building infrastructure technologies across computing, defence and energy. It looks for deeply technical teams with in-house science and engineering expertise, defensible IP moats in fundamental hardware or low-level software, and paths to billion-dollar revenues over a decade. The firm grew out of a community of more than 15,000 deeptech founders.
