Ecosystem Integrity Fund

Managing Partners James Everett and Devin Whatley co-lead the fund. Everett authored the fund strategy, chairs the Investment Committee, and directs research and due diligence. Whatley co-leads deal structuring, negotiations, and portfolio company engagement, drawing on over 30 years in sustainability and technology commercialization.

EIF targets early-growth stage companies where a critical business problem overlaps with a sustainability problem. It focuses on six themes — renewable energy, transportation, agriculture and food, climate resilience, green chemistry, and waste reduction — and seeks niches that are undercapitalized but positioned for near-term adoption within large, slow-changing industries.

No. EIF operates as an independent, sustainability-focused venture capital manager raising discretionary private funds. It is not a family office or a captive corporate venturing vehicle.

EIF makes direct equity investments in operating companies. It does not present itself as a fund-of-funds or LP in other managers. Board seats at companies like ZeroAvia, Sunverge, and Liminal confirm a direct, active-ownership model.

EIF's mandate excludes hydrocarbon energy, conventional internal combustion engine vehicle manufacturing, and extractive agriculture. The firm structures its portfolio in opposition to legacy industrial systems that it views as economically and environmentally unsustainable.

EIF has not publicly disclosed its limited partner base. Senior Partner Geoffrey Eisenberg leads fundraising and investor relations, and the firm markets itself to institutional investors seeking sustainability exposure, but specific LP identities and commitment amounts remain private.

EIF invests heavily in system-level research to identify market niches before they become crowded. The firm describes its approach as resistant to hype, deliberately charting a course into under-studied pain points where sustainability economics are compelling but venture competition is thin.
