1Seed is a London-based early-stage venture capital firm founded in 2011 that invests its own capital into seed-stage technology startups. The firm typically leads or participates in very early funding rounds, usually investing between GBP25,000 and GBP100,000 per deal as part of total seed rounds of roughly GBP50,000 to GBP500,000. It focuses on pre-revenue or early-product companies, primarily in software, digital platforms, and internet-based business models. 1Seed operates as a hands-on investor, providing mentorship, network access, and operational support alongside capital, often helping startups secure additional co-investors through its network of angels and funds. Its investment model is highly founder-centric and concentrated on very early-stage UK and European startups.
