The Chan Zuckerberg Initiative (CZI) is an organization established and owned by Facebook founder Mark Zuckerberg and his wife Priscilla Chan with an investment of 99 percent of the couple's wealth from their Facebook shares over their lifetime. The CZI is set up as a limited liability company (LLC) and is an example of philanthrocapitalism. CZI has been deemed likely to be "one of the most well-funded philanthropies in human history". Its creation was announced on 1 December 2015, for the birth of their daughter, Maxima Chan Zuckerberg. Priscilla Chan has said that her background as a child of immigrant refugees and experience as a teacher and pediatrician for vulnerable children influences how she approaches the philanthropy's work in science, education, immigration reform, housing, criminal justice, and other local issues.
