Join Us

Solidaire Action gives quickly and generously and advocates courageously to repair the past and ongoing harms of society’s and philanthropy’s disinvestment from Black, Indigenous, immigrant, and other communities excluded from political power.

We are guided by our desire to be transformational rather than merely transactional, to bring more money, and more than money to the movement ecosystem and to our approach.

We do our part to invest in power-building by communities that have suffered inequity across generations, experiencing oppression and exploitation upon which the current political system has been built.


Solidaire members represent a wide range of roles within the broader giving ecosystem. From individual wealth inheritors and first generation earners, to those with positions on philanthropic boards and those who develop programmatic and grantmaking work, to those who advise and organize wealth holders, our members are poised to make an impact across philanthropic organizing.

Below are some figures that help give more life and depth to our vibrant, intergenerational community:
