The Ecosystem Integrity Fund

The Ecosystem Integrity Fund is a private equity and venture capital firm based in San Francisco, with offices in Los Angeles and New York, that targets early- to late-stage investments in environmental sustainability and climate-related sectors. It backs companies and projects in clean technologies, energy, transportation, water, agriculture, building materials, waste management, habitat conservation, and related areas that advance resource efficiency and biodiversity while addressing threats to ecosystem integrity such as land fragmentation and contamination. Typical initial commitments range from about 0.5 million to 5 million dollars, with investments primarily in North America and increasingly global opportunities. The firm seeks both financial returns and measurable ESG impact by supporting scalable solutions across energy, climate resilience, and environmental remediation.
