About Stolte Family Foundation
The Stolte Family Foundation concentrates its giving in the Seattle/King County area, providing flexible general operating support to a small number of repeat grantees focused on climate policy and broad community needs. Nearly all grant dollars went to two organizations—Climate Solutions and United Way of King County—indicating a dual interest in regional climate advocacy and funding pooled community services. The foundation favors unrestricted support that enables grantees to sustain operations and scale impact.

About Stolte Family Foundation
A defining feature of the Stolte Family Foundation is its repeated, large unrestricted support for a small set of Seattle-area organizations. Climate Solutions - Seattle received $700,000 in 2023 and again in 2024, while United Way of King County received $602,500 in 2023 and $650,000 in both 2024 and 2025. Those recurring awards point to a grantmaker that backs multi-year operating capacity rather than one-time project funding. The foundation’s giving reaches both climate policy work and broad community services. In the climate space, it has supported organizations working on clean energy transition, emissions reduction, and policy advocacy. In community services, it has funded pooled support for local needs through United Way of King County and other nonprofit infrastructure organizations in the region. Its recent grants also show a preference for general charitable operations across mid-sized nonprofits, including Community Center for Education Results, Evergreen Collaborative, and Washington Alliance for Better Schools. The overall pattern is concentrated, relationship-based, and centered on organizations that can use flexible funding to sustain ongoing work in Washington communities.
What Stolte Family Foundation Funds
Climate advocacy is a central theme. The foundation gave $600,000 in 2025 to Climate Solutions - Seattle for general charitable operations, and it also supported Evergreen Collaborative with $200,000 in 2023, $200,000 in 2024, and $200,000 in 2025. Those grants align with its climate pillar focused on a carbon-free economy, clean energy transition, and policy solutions. Education and family engagement appear as another thread. Community Center for Education Results received $469,128 in 2023, 2024, and 2025 for general charitable operations, matching the foundation’s education emphasis on closing opportunity gaps through family and community engagement. The foundation also funds civic participation and community power. Washington Progress Fund received $300,000 in 2023, and Utility Information Alliance received $300,000 in 2025, both as general charitable operations. That pattern fits its civic engagement pillar, which supports organizing, infrastructure, and rural community work in Washington state.
How Stolte Family Foundation Gives
Typical grants cluster around a middle range: p25 is $31,688, median grant size is $60,000, and p75 is $100,000. The recent grant list shows many awards above that range, including repeated six-figure operating grants. The foundation appears to use a recurring, multi-year model rather than one-off support: several recipients appear in consecutive years, especially from 2023 through 2025. It is a regular funder and also makes program-related investments. The grants shown are almost entirely described as general charitable operations, which suggests flexible support is a core part of how it gives.
