Somewhere in your donor file is a major gift you've never asked for. Greenfield screens your entire database against public records and hands you the shortlist — for a fraction of what the big wealth vendors charge.
Get a free database screen Free. No subscription. No sales call required.You already know your top givers. It's the rest of the file you can't see.
The retired business owner giving $50 a year. The quiet family with land, stock, a foundation seat. Every donor file has them — and no small shop has time to find them. Wealth-screening subscriptions start in the thousands per year and hand back unverified batch guesses; a development office costs far more. So the hidden major gifts stay hidden.
Your file, worked the way a nine-figure development shop works theirs.
Your entire database checked against public records — property, business ownership, securities filings, foundation ties — and against your own giving history, the signal the vendors never use.
The strongest signals get researched by hand — right person, real assets, every claim linked to its evidence. No unverified batch guesses, ever.
You get a shortlist: who to ask, for how much, and when — with the reasoning attached. We do the legwork. You make the ask.
Greenfield was built by a donor-operations professional who designs and runs donor qualification for a nine-figure national nonprofit — the same screening, research, and assignment discipline the largest shops use, rebuilt for organizations that can't spend six figures on development.
Also available: right-sized donor CRM setup for brand-new organizations — no $500-a-month software required.
