USA by Donation Causes

Family offices identified by their documented charitable giving — not by what they invest in. Every office in these lists is matched to a recorded cause, and where available to the family's own foundation, the organizations they have funded, and a source reference (IRS 990-PF filing, foundation website, or public donor listing).

Each list includes verified websites and LinkedIn pages, top decision makers with personal LinkedIn profiles and work emails, and a column flagging giant family offices — 13F institutional filers and known billionaire families.

Built for nonprofit development teams, foundation fundraisers and philanthropic advisors who need to reach families with a proven history of giving to their cause.
