There are too few voices that critique the philanthropic sector whom foundation leaders will listen to. Vu Le, and his blog platform, Nonprofit AF, have emerged as a nonprofit-industry resource calling out unhelpful giving behavior and providing unvarnished and useful feedback to grantmakers. AmbitioUS’s work is to influence foundations to use unconventional practices in order to support systems change, and Vu’s voice contributes to a climate of receptivity among foundation leaders to question status quo in favor of responding to constituents’ terms of engagement. AmbitioUS is providing a one-year unrestricted grant that acts as a fellowship to financially enable Vu Le, an important and trusted critic of foundation practices, to continue to develop and provide compelling storytelling that fosters foundation leaders’ receptivity to change.
