Will Martin is the Founder and Director of Portfolio Ventures, a London-based UK seed fund and angel network he co-founded with Will Brooks in October 2014 to support early-traction startups [1][4][7]. His investment thesis targets pre-seed and seed-stage companies across fintech, insurtech, AI, SaaS, and consumer internet, primarily within the UK and EMEA regions including the Middle East and Africa [1][2][3]. While individual angel check sizes are cited as $0–$50K, the firm’s typical investment ranges from £100,000 to £500,000, though his specific lead or follow behavior is not explicitly detailed [2][8][11]. Notable portfolio companies include Marshmallow, Swap, Credit Kudos, PensionBee, and The Electric Car Scheme [8]. Martin emphasizes connecting early-stage firms with capital, mentorship, and a founder-focused network rather than publishing distinctive public writing or a unique point of view [2]. His track record includes 58 investments and 6 exits across 56 companies [3].
