Ecosystem Integrity Fund (EIF) is a venture capital firm investing in companies which create practical solutions for environmental sustainability. The fund focuses on businesses addressing major challenges like climate change, resource efficiency, and ecosystem health, supporting innovations in clean energy, transportation, and sustainable products. EIF works closely with its portfolio companies to help them scale, aiming for both strong financial returns and measurable positive impact on the environment.

A clear example of EIF’s impact is its investment in ZeroAvia, a company developing hydrogen fuel cell technology for airplanes. ZeroAvia retrofits existing aircraft with engines powered by hydrogen, replacing traditional jet fuel and enabling zero-emission flight. The company has formed partnerships with major airlines—including United, Alaska, and British Airways—and leading manufacturers like Amazon and Mitsubishi Aircraft. By making air travel cleaner, ZeroAvia helps reduce carbon emissions and supports the shift to a low-carbon economy. EIF’s early investment in ZeroAvia reflects its strategy of backing scalable, systems-level solutions to environmental challenges, and the fund continues to support the company’s growth through follow-on investments.

The fund focuses on technology-enabled businesses across healthcare, education, economic empowerment and environmental sustainability, supporting underrepresented founders who bring new solutions to underserved markets and communities.

A clear example of Rethink Impact’s work is its investments in two digital care platforms: Bold and Wellthy. Bold is designed to help older adults improve strength, balance and mobility through evidence-based programs delivered in partnership with healthcare providers. These programs have led to fewer fall-related hospitalizations and increased physical activity among patients. Wellthy provides care coordination services for individuals managing caregiving responsibilities, helping families navigate complex healthcare systems and access needed support. Together, these investments show how Rethink Impact supports solutions to deliver meaningful health and quality-of-life benefits for individuals and families.
