Ian Hogarth

Ian Hogarth is a London-based solo angel writing $100k-$250k checks at pre-seed and seed across health IT software and AI/ML in healthcare, with deep AI credibility from his Air Street Capital work, the State of AI Report, and his role as chair of the UK AI Safety Institute. Founders building AI-native healthcare software in Europe, applied ML in clinical workflow, or anything where serious AI defensibility matters are the right fit. He is one of the most informed AI investors in the UK ecosystem and brings significant signaling value plus a wide network into AI research, government, and corporate AI. The check size is meaningful for a pre-seed and a useful high-signal participant in a seed round. He is the wrong audience for non-AI healthcare, biotech without a computational angle, or devices. UK and European founders should prioritize him; US founders are a viable but secondary fit if there’s a credible UK or European angle. Outreach via Twitter (@soundboy) or LinkedIn is viable given his public posture and engagement with AI founders, though warm introductions through Air Street, Plural, or the UK AI research community will materially outperform cold notes. Bring substantive AI thinking, not LLM-wrapper pitches. Without a published thesis statement in this profile, founders should rely on his public writing as the primary signal of fit.
