Planeteer Capital is a New York-based venture capital firm founded in 2022 by climate-tech investor and operator Sophie Purdom. The firm closed its debut $54 million fund in 2025, focusing on pre-seed and seed-stage investments in climate technology startups. Planeteer is committed to backing founders with "nonlinear ambition and otherworldly urgency," aiming to address the pressing challenges of climate change through innovative solutions.
Planeteer Capital targets asset-light companies operating in sectors such as food and land use, manufacturing, buildings, and climate-risk mitigation and adaptation. The firm invests globally, seeking startups that leverage technology to reduce greenhouse gas emissions and help communities adapt to climate change.
In 2025, Planeteer Capital announced the close of its first fund, totaling $54 million. The fundraising process spanned two years and concluded below the initial $75 million target and $100 million cap.
Despite a challenging fundraising environment for climate-focused ventures, the fund secured backing from notable limited partners, including former Meta CTO Mike Schroepfer, an Ivy League university endowment, Pivotal Ventures (founded by Melinda French Gates), and various corporations and foundations.
The fund aims to invest in early-stage, asset-light climate-tech companies, with a focus on sectors like food and land use, manufacturing, buildings, and climate-risk mitigation and adaptation.
