| Type | Philanthropic network | Philanthropic network |
| Fondé | 2010 (Founded by Warren Buffett, Melinda French Gates and Bill Gates in 2010; formally announced in June 2010 with 40 initial signatories, all in the United States. The Giving Pledge publishes no office address of its own; it is "a separate but affiliated community operationally hosted by the Gates Foundation", which is based in Seattle.) | 2012 (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.) |

| Primary audience | Individuals and couples with a net worth of at least one billion dollars, or who would be billionaires but for their giving | 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 |
| Membre type | Signatories are billionaires and billionaire couples who have publicly committed to give the majority of their wealth to philanthropy during their lifetime or in their wills. Most publish a signed letter explaining their reasoning. A separate Next Generation group, created in 2014, has more than 300 active members worldwide aged 18 to 75, drawn from the children and grandchildren of signatories; their identities are not disclosed because they did not personally sign the pledge. | 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. |

| Application process | Someone who meets the billionaire threshold and is ready to make the public commitment contacts the Giving Pledge to express interest. There is no published application form, review committee, sponsorship requirement or interview stage. In the early years Gates, French Gates and Buffett recruited signatories directly.

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. |
