SCOREScore Breakdown

D
29
Giving score
uses a net worth as of 2025

The giving score is a weighted average of 2 components. The formula is open and versioned — the weight percentages below show how much each component contributes to the final score.

Philanthropy65% weight
19%

Evidenced charitable giving — built on what they actually give each year, not parked assets. Dominated by generosity (annual giving relative to net worth — the share of your fortune you give), plus the absolute scale of that giving, plus a small nudge for signing the Giving Pledge (a commitment, not a realized action).

Data: ProPublica 990 charitable disbursements, net worth, The Giving Pledge registry

Data coverage35% weight
50%

How much sourced public record we hold about this person — net worth, SEC filings, foundation 990s, news coverage, Wikidata. It measures our coverage, not how open the person is. Each further kind of record scores higher, up to eight. Political donation records matched to a person by name alone are not counted: they may belong to someone else with the same name. From October 7, 2026, our own AI-written summary and the profile photo are not counted either — neither is a public record — so grades that leaned on them moved down that day.

Data: SEC EDGAR, ProPublica 990s, GDELT / NewsAPI, Wikidata

Formula (v2): Giving score = 65% x Philanthropy + 35% x Data coverage

Scored on 10/16/2026 on a 0–100 scale. The score uses only the signals we have populated data for. Goal Impact, Controversy, and Community Approval are deferred until that data exists — Phase 1 goal adoption, controversy detection, and community votes respectively.
