About this grant
TSP Ventures operates the Pathfinder Fund as part of its mission to invest in early-stage, hard science, and breakthrough technologies that deliver critical resources—including clean air, freshwater, food, reliable energy, metals and minerals, steel and cement, plastics and chemicals, and rare earths. The fund addresses global challenges driven by four macro forces: demographic growth (1.5 billion more people by 2050, 4 billion entering the middle class), climate and environmental change (extreme weather, planetary boundary tipping points, land degradation), geopolitical instability and fractured supply chains, and massive resource demands from AI infrastructure. TSP Ventures invests across five vertical sectors: Future Power & Energy (renewable energy, grid infrastructure), Future of Food & Water (harvesting, desalination, sustainable agriculture), Critical Materials (sustainable extraction, synthesis, recycling), Carbon Mitigation (carbon capture, heavy industry decarbonisation), and Adaptation, Circularity & Waste (recycling, e-waste management, climate resilience). The fund provides hands-on business, commercial, and financial support to portfolio companies, with a track record of 25 investment rounds, 2 exits, 1 partial exit, 8 up-rounds, over £10 million deployed, and over £75 million in follow-on funding unlocked since 2019.
