Investment thesis
TSP Ventures backs early-stage, hard science and breakthrough environmental technologies that supply critical resources (clean air, water, food, energy, metals and minerals, steel and cement, plastics, rare earths) more cost-effectively, sustainably and securely. Driven by macro forces of demographics, climate change, geo-security and AI's resource demands, the firm targets five verticals: future power and energy, future of food and water, critical materials, carbon mitigation, and adaptation, circularity and waste. It provides hands-on business, commercial and financial support to improve start-up success rates, often leading or co-leading rounds and taking board seats.
