TSP Ventures

TSP Ventures

TSP Ventures launched in 2013 under co-founders Colin Campbell and Charles Seely. The firm operates from a single conviction: the most consequential financial returns of the next two decades will come from companies that slash carbon emissions in hard-to-abate sectors. It concentrated its entire strategy on that thesis before climate tech became a congested category. The firm targets pre-seed and seed-stage companies across Europe and North America, typically as the first institutional investor in a round. Its portfolio spans electric mobility, alternative proteins, energy storage, and circular-economy infrastructure. Confirmed positions include publicly reported holdings in Vertical Future, a London-based vertical-farming company, and Tevva Motors, the electric-truck manufacturer. The firm co-invests alongside specialist climate funds and angel networks, structuring primarily direct equity deals rather than fund-of-funds commitments. Team size remains lean, consistent with the model of a focused early-stage investor. No additional offices beyond London are disclosed. In November 2022, TSP Ventures participated in Vertical Future's £8 million top-up round, which brought the company's total Series A to £27 million (per Sifted, November 2022). The firm does not publicize an aggregate AUM figure. TSP Ventures pursues a remodeling thesis — backing companies that replace high-carbon infrastructure rather than layering software optimization onto incumbent systems. This hardware-forward, asset-heavy bias differentiates it from many early-stage climate investors that favor asset-light SaaS models. The partnership structure places investment authority with the founding team, maintaining a governance footprint consistent with a specialist boutique rather than a multi-strategy platform.
