Charitable foundations are organizations that provide financial support to various causes, such as education, health, and social services. They typically receive funding from individuals, families, or corporations and distribute grants to non-profit organizations or projects that align with their mission. These foundations can be private, funded by a single source, or public, supported by multiple donors. Examples include the Bill & Melinda Gates Foundation and the Ford Foundation. Their goal is to address societal issues and improve the quality of life for communities in need through strategic philanthropy.
