Most environment grants target established nonprofits. GrowthSeed's open program sits in a different lane: it funds environmentally conscious entrepreneurs and small businesses working on sustainability goals like energy infrastructure retrofits.

What we know: GrowthSeed is a small Illinois-based foundation with total assets around $247,000. Its 990 history shows a foundation-wide median grant of $500, so the $20,000 ceiling is the upper bound, not the typical award. The application is straightforward: org name, applicant details, requested amount, description of how funds will be used, expected impact, and one attachment.

Realistic fit: early-stage sustainability ventures or small eco-focused businesses seeking modest seed funding for a specific project like an energy retrofit.

Two things to confirm before applying. First, the program page says "nonprofit or entrepreneur," so if you're a 501(c)(3) doing sustainability work, you're likely eligible, but the program leans toward entrepreneurial applicants. Second, given the foundation's size, expect awards well below the $20,000 ceiling.
