S tephen Butt is an American billionaire and a member of the Butt family, which owns the popular Texas-based supermarket chain, H-E-B. The company was founded by his great-grandmother, Florence Butt, in a small town in Texas in 1905. H-E-B (which stands for Howard E. Butt, his grandfather's name) has since grown into a massive and beloved retail giant, with hundreds of stores across Texas and in Mexico. The company is known for its fierce loyalty from its customers, its innovative private-label products, and its deep commitment to community service and philanthropy.

While his cousin, Charles Butt, served as the longtime chairman and CEO and is the public face of the company, Stephen has also had a long and influential career within the family business. He is the president of Central Market, H-E-B's upscale, gourmet grocery division, which he was instrumental in developing and expanding. The company remains privately held by the Butt family, and Stephen's substantial ownership stake is the source of his considerable fortune.
