Mize Family Foundation

The Mize Family Foundation (MFF), based in Houston, TX, is a small but highly distinctive grantmaker with an unusually explicit intersectional framework. Founded as a climate-focused foundation, MFF goes beyond traditional environmental philanthropy by making climate justice and diversity in the environmental movement core to every grantmaking decision. The foundation supports organizations across the United States and in sub-Saharan Africa, making it one of the few small family foundations with a genuine dual-geography portfolio of this kind.

The foundation's four core values define its approach: supporting emerging leaders (youth, women, grassroots activists), climate justice (centering marginalized communities disproportionately affected by climate change), ecosystem interdependence (wildlife, humans, and environment as interconnected), and trust in partners (providing general operating support rather than restricted project grants). The trust value is particularly notable: MFF explicitly provides unrestricted general operating funds, trusting grantees' vision and leadership rather than dictating program activities.

The 2025 grantee list demonstrates the foundation's theory of change in practice. Recipients span: African agroecology food systems transformation (Agroecology Fund Africa), economic inclusion for marginalized communities in the Global South (BOMA), diversity and inclusion capacity building within the US environmental sector (Center for Diversity and the Environment), community-centered wildlife conservation in Zimbabwe (Akashinga/IAPF), girls' education and empowerment in Northern Ghana (Northern Girls Initiative), Indigenous women's rights in Kenya (Samburu Women Trust), women-led grantmaking in Tanzania (Women Fund Tanzania Trust), and Black climate justice communities in the US (The Chisholm Legacy Project). This portfolio reflects extraordinary geographic, cultural, and strategic diversity for a foundation with $2.3M in assets.

The preselected model (no public open application process) combined with returning grantees suggests MFF builds long-term relationships with a core portfolio and adds a small number of new grantees annually. Organizations want to be known within MFF's referral networks in the climate justice, women-and-environment, and Africa-focused philanthropy ecosystems.

The Mize Family Foundation holds approximately $2.33 million in assets. At the 5% minimum payout, annual grantmaking plus expenses totals at least $117,000. Given the active 2025 grantee list (7-8+ organizations), typical individual grants are likely in the $10,000–$20,000 range, with some returning grantees potentially receiving slightly higher amounts. Total annual grantmaking is likely in the $100,000–$150,000 range.

The general operating support model means grants flow directly into organizational budgets rather than being restricted to specific activities. For organizations operating on limited budgets — as many of the African-led grassroots organizations do — even a $10,000–$15,000 unrestricted grant from MFF can be strategically significant. The combination of general operating support with a $2M+ endowment allows the foundation to sustain multi-year relationships.

The US and sub-Saharan Africa dual geography is unusual for a foundation of this size. Most small US-based foundations either focus exclusively on domestic issues or exclusively on international development. MFF's portfolio spans both — US-based organizations like the Center for Diversity and the Environment and the Chisholm Legacy Project receive the same consideration as African-led organizations in Ghana, Kenya, Tanzania, and Zimbabwe. This suggests the Mize family has genuine personal connections or travel experiences in sub-Saharan Africa alongside their US climate advocacy work.

The returning grantee model is financially significant for eligible organizations: once you're in the portfolio, renewal grants are likely, reducing the transaction costs of annual fundraising. Building a relationship with MFF is therefore a medium-to-long-term investment.

Mize Family Foundation operates at an intersection that very few funders of any size occupy: US and African climate justice philanthropy, with an explicit diversity and gender equity overlay. National peers in the climate-justice-and-diversity space include the Patagonia Environmental Grants Program, the Solidago Foundation, the New World Foundation's environmental justice programs, and the Chorus Foundation. At larger scales, the Blue Green Alliance Foundation and the Hewlett Foundation's environment program address similar themes.

For the sub-Saharan Africa environmental philanthropy component, MFF operates in a space alongside organizations like the African Women's Development Fund, the African Philanthropy Network, and US-based foundations with significant Africa portfolios including the Christensen Fund and the BAND Foundation. The specific combination of wildlife conservation (Akashinga), Indigenous rights (Samburu Women Trust), agroecology (Agroecology Fund Africa), and women's funds (Women Fund Tanzania) reflects careful curation by a founder with deep Africa knowledge.

The Center for Diversity and the Environment is a well-known US grantee in the diversity-in-environmentalism space — other foundations funding CDE include the Wilburforce Foundation, Patagonia, and Rockefeller Brothers Fund. MFF's alignment with this organization signals participation in the broader JEDI (Justice, Equity, Diversity, Inclusion) in conservation philanthropy movement that has grown rapidly since 2020.

For small family foundations, MFF's explicit values articulation, transparent grantee lists, and dual-geography portfolio place it among the more sophisticated and mission-aligned small foundations nationally. Organizations already connected to networks like the Funders Network for Smart Growth, the Climate and Clean Energy Equity Fund, or the African Philanthropy Forum would likely have natural access points to MFF's attention.

The Mize Family Foundation announced its 2025 grantees on the website, confirming active grantmaking through at least the current year. The 2025 portfolio includes both new and returning grantees across the US and sub-Saharan Africa, demonstrating consistent programmatic engagement. Previous grantee lists from 2021 through 2024 are also published on the website, providing a rich record of the foundation's evolving priorities.

The 2025 grantee slate reflects geographic breadth: Agroecology Fund Africa (Pan-African), BOMA (global but Kenya/Africa focused), Center for Diversity and the Environment (US), Akashinga (Zimbabwe), Northern Girls Initiative (Ghana), Samburu Women Trust (Kenya), Women Fund Tanzania Trust (Tanzania), and The Chisholm Legacy Project (US). This diversity suggests MFF actively curates its portfolio to maintain geographic balance between US domestic and African international grantees.

The Grantee News section of the website documents ongoing grantee activities and outcomes, indicating the foundation maintains active relationships with portfolio organizations and tracks impact. This engagement culture reflects the "trust in partners" value and creates natural opportunities for grantee organizations to communicate progress and deepen the relationship.

The foundation's website was last updated in 2024, with the copyright footer reflecting current operation. The Houston, TX base does not appear to influence grantmaking geographically — none of the current grantees are Texas-based.

Mize Family Foundation does not have a public application process. Organizations seeking to engage should focus on building visibility within the foundation's networks and demonstrating alignment with its specific values framework. Key strategies:

1. Operate at the intersection of climate, diversity, and either US or sub-Saharan Africa. MFF's portfolio is highly specific: climate justice work that explicitly centers marginalized communities and diverse leadership. Organizations doing conventional environmental conservation without equity and inclusion dimensions, or equity work without climate connection, are poor fits. The intersection is non-negotiable.

2. Sub-Saharan Africa organizations: be African-led. Every African grantee in MFF's portfolio is led by African staff serving African communities — Northern Girls Initiative in Ghana, Samburu Women Trust in Kenya, Women Fund Tanzania, Akashinga in Zimbabwe. MFF is not funding US-based international development organizations working in Africa. It is funding African-led organizations. This is a critical distinction.

3. US organizations: prioritize diversity and equity in the environmental movement. The Center for Diversity and the Environment and The Chisholm Legacy Project both focus on building diverse leadership within the climate and environmental movement rather than on a single environmental issue. Organizations building capacity for marginalized groups to participate in and lead environmental action are the strongest US candidates.

4. Operate with unrestricted funding compatibility. MFF provides general operating support — not project grants. Your organization should be able to clearly articulate how unrestricted funding would strengthen your mission and operations. A strong organizational sustainability narrative and credible leadership team are more important than a detailed project plan.

5. Build connections through shared grantee networks. MFF's current and past grantees are connected through networks including the Center for Diversity and the Environment's alumni, African Philanthropy Forum members, and JEDI-in-conservation networks. Connecting with these organizations creates natural pathways to the Mize family's attention. Attending conferences like GreenState, the African Philanthropy Forum, or NAAEE (North American Association for Environmental Education) builds visibility in these networks.
