Key people at Planeteer Capital.
Planeteer Capital is a New York-based venture capital firm founded in 2022 that invests in early-stage climate technology startups with a strong focus on sustainability and environmental innovation. Its mission is to back founders with "nonlinear ambition and otherworldly urgency" who are developing asset-light solutions to reduce greenhouse gas emissions and help communities adapt to climate change globally. The firm primarily targets pre-seed and seed-stage companies in sectors such as food and land use, manufacturing, buildings, and climate-risk mitigation, aiming to drive positive environmental impact through technology[1][2].
Founded and led by Sophie Purdom, a seasoned climate-tech investor and operator, Planeteer Capital closed its debut $54 million fund in 2025 after a two-year fundraising process. The firm employs a thesis-driven investment philosophy, focusing on leading rounds and providing strategic support beyond capital to help startups scale and navigate the complexities of climate tech markets. Planeteer leverages Purdom’s extensive network and deep sector expertise to build a portfolio of innovative companies addressing urgent climate challenges[1][3][4].
Planeteer Capital was founded in 2022 by Sophie Purdom, who has a strong background in climate technology investing and operations, including co-founding Sightline Climate, a market intelligence platform for climate tech. The idea for Planeteer emerged from Purdom’s recognition of the need for focused early-stage capital dedicated to climate solutions with high urgency and ambition. The firm’s debut fund closed in 2025 with $54 million, slightly below its initial target, reflecting a challenging fundraising environment but strong conviction in its mission[1][4].
Planeteer Capital rides the accelerating global trend toward climate innovation and sustainability, addressing the urgent need for scalable solutions to climate change. The timing is critical as climate tech faces both increasing demand and a challenging funding environment, especially at early stages. By focusing on asset-light, technology-driven startups, Planeteer aligns with market forces favoring scalable, capital-efficient solutions that can rapidly reduce emissions and improve climate resilience. Its influence extends through its network and portfolio, helping shape the emerging climate tech ecosystem and encouraging innovation in key sectors like food, manufacturing, and adaptation technologies[1][4].
Looking ahead, Planeteer Capital is poised to deepen its impact by continuing to back ambitious founders with breakthrough climate solutions. Trends such as increased regulatory pressure on emissions, growing corporate climate commitments, and advances in technology will likely shape its investment focus. As the climate tech ecosystem matures, Planeteer’s role as an early-stage specialist with strong operational support could become increasingly vital in bridging the gap between innovation and large-scale impact. Its future influence may expand through follow-on funds and broader ecosystem engagement, reinforcing its mission to drive positive global environmental change[1][2].
Planeteer Capital stands out as a focused, mission-driven VC firm uniquely positioned to accelerate climate innovation at the earliest and most critical stages of startup development.
