Pivotal Philanthropies Momentum Foundation, formerly the Rosefinch Foundation, is a left-of-center private foundation associated with Pivotal Ventures, the umbrella entity for the philanthropic and advocacy activities of Melinda French Gates, which also includes the Pivotal Philanthropies Opportunity Foundation and the Pivotal Philanthropies Pathway Foundation. The foundation was one of several entities created to receive funds from Bill Gates as part of the couple’s 2021 divorce settlement and Melinda Gates’s 2024 departure from the Bill and Melinda Gates Foundation. The Momentum Foundation aligns with Pivotal Ventures’ broader left-of-center priorities, including expanding women’s political representation, advocating for government-funded caregiving, and supporting women’s health initiatives that encompass abortion and contraceptive access. ^{1 2 3}

Background

The Pivotal Philanthropies Momentum Foundation was established in 2023 and received tax-exempt status from the Internal Revenue Service (IRS) in December of that year. It initially operated under the name Rosefinch Foundation before adopting its current name. The foundation shares an address and leadership with other Pivotal Ventures entities and was created as part of Melinda French Gates‘s expansion of her independent philanthropic network following her divorce from Bill Gates. ^{1 4}

The foundation reported no grantmaking in its first year of substantial operations and held assets derived almost entirely from a single large contribution from Bill Gates. It operates alongside similar Pivotal-affiliated foundations that channel funds toward left-of-center causes, such as increasing the number of women in elected office and promoting policies like paid family leave mandates. ³

Activities

The Pivotal Philanthropies Momentum Foundation reported no independent activities, grantmaking, or programs in 2024. Its operations appear to be tied to the broader Pivotal Ventures network, which pursued left-of-center initiatives such as training women for political office and funding organizations advocating for left-leaning election reforms. For instance, Pivotal supported groups that aimed to increase the representation of left-of-center women and racial minority women in government, including efforts to recruit and train candidates for down-ballot races. ⁵

The network also backed campaigns for policy changes like expanded mandates for paid family and medical leave, framing such measures as essential to addressing gender inequities. In addition, Pivotal collaborated on global women’s health efforts, including a $250 million grant program that funded organizations addressing mental and physical health issues, with an emphasis on underserved populations. While Momentum itself did not participate in these grants, its assets position it to support similar activities in the future. ^{6 4}

Funding

The Pivotal Philanthropies Momentum Foundation received $982,228,982 in contributions in 2024, accounting for virtually all its revenue. This amount came from Bill Gates as part of a $12.5 billion agreement tied to Melinda French Gates‘s exit from the Gates Foundation. Similar transfers were made to other Pivotal-affiliated foundations, totaling over $10.8 billion across the network. ^{3 4 7 8}

People

Melinda French Gates has been the director of the Pivotal Philanthropies Momentum Foundation since its inception, with no reported compensation in 2024. French Gates, a longtime advocate for left-of-center causes, previously co-chaired the Gates Foundation and founded Pivotal Ventures in 2015 to focus on women’s issues. ⁹

All five foundations in the Pivotal network share the same street address and list Melinda French Gates as director, John Sage as president/treasurer, and Brooke Anderson as vice president/secretary. Anderson is Pivotal’s president, while Sage is a longtime advisor to French Gates. The same three individuals are also listed among the five officers/directors of the 501(c)(4) Pivotal Initiatives Fund. ⁴
