London funding landscape
London captures roughly two-thirds of UK VC funding by value each year. Deal density is high, but so is investor fatigue, warm intros from a shared portfolio company still outperform cold outreach 4:1.
Physical ecosystem hubs where London founders and investors gather: Silicon Roundabout, King's Cross, Level39 (Canary Wharf), Second Home. Being visible in these communities remains one of the highest-ROI activities for a first-time founder — most active London angels get their deal flow from other founders and portfolio companies, not cold outreach.
