TSP Ventures

TSP ('The Sustainable Path') Ventures is a London-based venture capital firm founded in 2019, focused on early-stage hard science and environmental technology startups. The firm targets companies working across five investment verticals: future power and energy, future of food and water, critical materials, carbon mitigation, and adaptation/circularity/waste. TSP primarily invests at pre-seed and seed stages, with the goal of helping companies reach a Series A raise and first commercial proof point. It operates via deal-by-deal SPVs backed largely by HNWIs and family offices, with investments typically structured as SEIS and EIS eligible. In June 2026, TSP launched the Pathfinder (S)EIS Fund — an FCA Sustainability Impact-labelled fund that raises and deploys capital annually across a portfolio of high-growth environmental tech companies. TSP has deployed over £10m across 25 investment rounds, unlocking £75m+ in follow-on funding, and has recorded 2 exits, 1 partial exit, and 8 up-rounds. The firm provides hands-on board-level support, fundraising guidance, and commercial coaching alongside capital. Founders can submit pitch decks directly via the Entrepreneurs page.
