Lowercarbon Capital, founded in 2018 by Chris Sacca, is a venture capital firm based in Jackson, Wyoming. The firm invests in companies that reduce carbon dioxide emissions, develop methods to extract carbon from the atmosphere, and explore techniques to cool the planet. Emphasizing market-driven solutions rather than moral pressure, Lowercarbon Capital supports startups that combine rigorous scientific research with bold goals to address climate change. Chris Sacca, who previously led investments at Google Ventures, leads the team in providing financial and operational support to early-stage innovators.
The fund focuses on technologies that aim to prevent new greenhouse gas emissions, remove carbon already in the air, and extend the window for climate solutions to scale. Investments target sectors such as renewable energy, sustainable agriculture, clean transportation and industrial processes, with funding stages ranging from seed to Series A. Beyond capital, the team offers hands-on guidance on product development, regulatory strategy and customer introductions. Lowercarbon Capital maintains a network of scientific experts and industry leaders to help founders refine their approaches and address critical technical challenges.
A notable theme in the portfolio is support for clean energy storage and battery innovation. The firm has backed companies like Breathe Battery Technologies, which develops smart control software to speed up charging and extend battery life, and Antora, which designs solid-state thermal batteries for industrial heat and grid stability. Lowercarbon Capital also invests in lithium extraction methods with Lilac Solutions and advanced fusion energy projects at Avalanche Energy and Commonwealth Fusion Systems. Additional holdings address low-carbon materials, such as zero-emission cement from Sublime, and carbon conversion platforms like Dioxycle.
