In 1987, Dubin was asked by fellow hedge fund manager and close friend Paul Tudor Jones to join him and Peter Borish in a venture philanthropy project Jones had conceived and started. The resulting Robin Hood Foundation has raised and granted more than $2 billion to fight poverty in New York City. The foundation finds, funds, and creates programs and schools that generate measurable results for families in New York's poorest neighborhoods. A rigorous system of metrics and third-party evaluation of these groups guarantees accountability. The board pays all administrative, fundraising, and evaluation costs, allowing 100% of donations to go directly to organizations helping New Yorkers in need. Dubin has served on the board since its founding, is a former Board Chair, and sits on the Jobs and Economic Security subcommittee.
