The Pisces Foundation appears to be a single-purpose funder: all reported giving (three grants totaling $54.95M) went to one recipient listed as “Attachment B.” This suggests the foundation makes large, donor-directed awards to a designated beneficiary or project rather than funding a portfolio of nonprofits. Because the grantee name provides no program detail, the specific policy or service area supported is not discernible from the data provided.
Highly concentrated: very few grants all to one recipient, large dollar amounts, repeat payments to the same beneficiary—indicative of one-off or multi-installment funding for a specific project or designated organization rather than broad diversified giving.
Pisces Foundation’s reported giving is dominated by three very large grants to a single recipient listed as Attachment B, with awards of $20,298,853 in 2023, $17,957,250 in 2024, and $16,696,100 in 2025. That pattern points to highly concentrated, designated grantmaking rather than a broad portfolio of many small awards. The foundation’s public grantmaking materials also show a clear environmental and climate orientation, with programs tied to One Water, environmental education, and collaboration-building in San Francisco. The foundation uses large, time-limited awards alongside program channels that support field-building and place-based collaboration. Its published descriptions emphasize collective action, policy change, and equitable environmental outcomes. In the San Francisco program, the focus is on high-impact collaboration and capacity-building to support civic, community, and environmental priorities in the city. Across the data provided, Pisces Foundation appears to fund through a mix of restricted, place-based, and field-building approaches, with the largest visible awards tied to a single named recipient rather than a diversified grantee set.
Environmental and climate work is the clearest theme in Pisces Foundation’s public program descriptions. Under Environment + Climate Grantmaking, the foundation supports collaboration and capacity-building to address global environmental and climate challenges, including policy change and equitable environmental outcomes. Water is another major area. The 2018 Urban One Water RFP funded integrated water management in mid- to large-size U.S. cities, with an equity lens and attention to policy, regulatory change, green infrastructure, and workforce development. The foundation also backed environmental education as field-building. Its 2019 Environmental Education Field-Building RFP supported backbone support, leadership, shared measurement, collective impact, and efforts to strengthen diversity, equity, inclusion, and cultural relevancy. A separate San Francisco program focuses on collaboration and capacity-building for civic, community, and environmental priorities in the city.
Pisces Foundation’s typical grant size is very large: p25 is $17,326,675, the median is $17,957,250, and p75 is $19,128,052. The reported grant record is extremely concentrated, with three grants in the file all going to one recipient. That pattern suggests recurring awards to a designated beneficiary rather than a broad open-grant portfolio. The foundation is classified as a regular funder, does not fund individuals, and does not make program-related investments. Its grants portal and RFP materials indicate invited applications rather than unsolicited submissions, with past public RFPs used for specific initiatives.

Notable grantees: Attachment B
The visible grant record is fully local in the dataset: 100% of grants went to recipients in California, and the recipient country distribution is entirely U.S. The top grant recipient city shown in the recent grants is San Francisco, where Attachment B is located. Program descriptions also point to San Francisco as a place-based focus, alongside broader U.S. funding through time-limited RFPs such as One Water and Environmental Education. The foundation’s place-based work is therefore centered in California, with San Francisco appearing as the clearest local hub.
Its program descriptions center on environmental and climate work, including collaboration and capacity-building, One Water and integrated water management, environmental education field-building, and San Francisco place-based collaboration. Those themes appear across the Environment + Climate Grantmaking, Urban One Water RFP, Environmental Education Field-Building RFP, and San Francisco program descriptions.
No. The grants portal and RFP materials indicate invited applicants, and the active program descriptions state that unsolicited applications are not accepted. Past public RFPs were used for specific initiatives such as One Water and environmental education field-building.
The typical award size is very large in the reported data: p25 is $17,326,675, the median is $17,957,250, and p75 is $19,128,052. The broader program descriptions also show smaller grant-size ranges for some initiatives, including $1,000–$500,000 for Environment + Climate Grantmaking and $1,000–$300,000 for San Francisco Grantmaking.
The dataset shows all reported grants going to recipients in California, with 100% of grants in the HQ state. The recipient country distribution is also fully U.S.-based, and San Francisco appears in the recent grants list as the location of the named recipient.
The grant record suggests recurring support to a single beneficiary: three reported grants in 2023, 2024, and 2025 all went to Attachment B. That pattern points to repeated awards rather than a wide, one-off distribution across many nonprofits.
