A lexandra Daitch is an American heiress and one of three sisters who inherited a significant stake in Cargill, one of the largest privately held companies in the world. She is a great-granddaughter of William W. Cargill, who founded the agribusiness behemoth in 1865 as a single grain storage warehouse. The company has since grown into a global giant with operations spanning the entire food supply chain, from agricultural commodities trading to food processing and risk management.

Like the other Cargill and MacMillan family heirs, Alexandra Daitch is not involved in the day-to-day management of the company. The family has long maintained a policy of professional management while retaining ownership. Her wealth is derived from the dividends and valuation of her share in the massive, deeply entrenched family enterprise. The family is known for its privacy, and Daitch, like her sisters, maintains a very low public profile.
