Planeteer Capital
InvestorActivePlaneteer Capital is a New York-based venture fund founded by Sophie Purdom, who also co-founded Sightline Climate and writes the influential CTVC newsletter covering the climate tech sector. The firm closed its debut $54M fund in 2025, investing at pre-seed and seed stages with checks of $1M-5M in climate tech, targeting a limited number of founders with what the fund calls 'nonlinear ambition and otherworldly urgency.' Backed by LPs including former Meta CTO Mike Schroepfer, an Ivy League endowment, and Melinda French Gates' Pivotal Ventures, Planeteer brings strong climate sector visibility and networks to portfolio companies.
