| Founded | 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.) | 2001 (Synergos states the GPC's mission "arose in 2001, from a series of events with fellow philanthropists hosted by Synergos' founder Peggy Dulany and her late father, David Rockefeller Senior".
