About CZI

The Chan Zuckerberg Initiative was founded in 2015 to help solve some of society’s toughest challenges — from eradicating disease and improving education, to addressing the needs of our communities. Through collaboration, providing resources and building technology, our mission is to help build a more inclusive, just and healthy future for everyone. We engage directly in the communities we serve because no one understands how to address our society’s challenges better than those who live them everyday. These partners help us identify problems and opportunities, learn fast and iterate toward our audacious goals for the next century. We strive to be humble, empathetic and life-long learners who work collaboratively to develop community-centered solutions. To help build a more just, equitable future, we embrace people from all backgrounds and experiences, who challenge each other’s assumptions with fresh perspectives. To that end, we are co-creating an environment where everyone feels respected, valued and we celebrate the beauty in the diversity of our shared strength.
