Solidaire Network membership requirements

Every criterion Solidaire Network publishes, with its source, the date it was verified and how confident we are in it — plus superseded figures, so you can see how the tests have moved.

Read a requirement as the organization's published floor, not as a promise. A revenue test may have alternative versions for different business types, chapters can set stricter local tests, and invitation-only bodies publish criteria that describe members rather than admit them.

How admission works

Application process

Prospective members complete an interest form on the membership page, indicating which categories apply to them and how they heard about Solidaire. The donor organising and philanthropic transformation teams then follow up. Separate individual and institutional membership documents are linked from the page. New members receive an orientation packet. Solidarity Circles are joined by separate application.

Invitation required

Sponsor required

— not documented by the organization or a source we could verify

Selectivity

Not publicly disclosed — no acceptance rate or review process is published. The effective filters are the $50,000 giving-capacity expectation and alignment with Solidaire's stated political principles.

Membership term

— not documented by the organization or a source we could verify

Primary audience

Individual wealth holders able to move $50,000 or more a year in giving, and professional staff and trustees at grantmaking foundations, who want to direct money toward left-of-centre social justice organising

Typical member

Individual members are people with wealth who can generally move $50,000 or more in annual giving, whether personally or through a family foundation, donor-advised fund or family office, and who are aligned with Solidaire's stated values. Institutional members are foundation professionals: Solidaire says about 40 per cent of its membership works at foundations of all sizes. The joining form also names donor advisors, money coaches, current and prospective foundation trustees and philanthropy-serving organisation staff as relevant categories.
