Solidaire Network
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
A profile page holds what the organization publishes and what named sources report: who it admits, what it costs, how it is structured, where it operates, and how it has changed. Every figure carries the date it was checked. A dash means the organization does not publish that fact.
Founding: Sources differ. Wikipedia's article on co-founder Leah Hunt-Hendrix dates the network's founding to 2012; Solidaire's own site says it has been embedded in justice movements "for a decade" and its published timeline begins in 2015. Solidaire Network Inc received its own IRS tax exemption only in May 2020, having previously operated under fiscal sponsorship, so the incorporation date and the founding date are different things.
Solidaire Network is a US membership network of donors and foundation professionals that directs money toward left-of-centre social justice organising, and organises its own members to do it. It describes itself as an intergenerational and cross-class community of donor organisers, and its stated approach, Transformative Donor Organizing, treats wealth holders as a constituency to be organised in the same way frontline movements organise their own. Individual membership is aimed at people who can generally move $50,000 or more a year in giving, personally or through a family foundation, donor-advised fund or family office. Institutional membership serves foundation staff, who make up around 40 per cent of the membership. The network runs on member-driven structures: Solidarity Circles that members form around topics and run on their own schedule, regional hubs, biweekly virtual meetings called Beloved Fridays, a rapid-response giving listserv for member-led resource mobilisations, an annual in-person network gathering, and drop-in caucuses on philanthropic transformation. Alongside membership, Solidaire operates pooled vehicles including Building the Fire Fund, the Janisha R. Gabriel Movement Protection Fund and the Leadership and Legacy Initiative. It reported revenue of $27.1 million in the year to June 2025.
How it works
Prospective members submit an interest form describing which category they fall into (individual wealthy donor or member of a high net wealth family, donor advisor or money coach, current or prospective foundation trustee, foundation staff, or philanthropy-serving organisation staff) and Solidaire's donor organising and philanthropic transformation teams follow up. Members then plug into whichever structures suit them: Solidarity Circles they can apply to join, a regional hub, biweekly Beloved Fridays calls, the rapid-response giving listserv and the annual network gathering. Members give directly to organisations they choose and can also contribute to Solidaire's pooled funds.
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.
Membership requirements
Requirements in detail, with history →Requirements are the tests the organization itself publishes: an age ceiling, a company-revenue floor, a net-worth minimum, a role. Where a figure straddles a range, the organization's own assessment decides. Local chapters can apply stricter tests than the published standard.

Structure and programming
Independent context
Solidaire sits at the activist end of the philanthropic network spectrum, and it does not disguise that: its published principles state that wealth is accumulated through exploitation and must be liberated, and its members have joined tax-the-rich lobbying days. Prospective members should read that as a genuine filter rather than positioning. The $50,000 annual giving threshold is meaningfully lower than the $1 million commitments asked by Women Moving Millions or the Synergos Global Philanthropists Circle, which makes it accessible to a wider band of donors, and the roughly 40 per cent share of institutional members means a good part of the room is foundation staff rather than principals. Two gaps stand out. Membership dues are not published anywhere on the site (the detail sits inside Canva documents linked from the membership page) and no member count is given. The organisation is financially substantial, with $27.1 million in revenue in the year to June 2025 against $15.5 million in expenses, but that figure covers its pooled funds as well as membership operations.
