278. Joseph Grendys
His $3.3 billion (est. sales) poultry processor, Koch Foods, slaughters, ships and sells chicken directly to customers and companies nationwide. (If you’ve had a Burger King nugget, you’ve probably eaten a Grendys bird.) Grendys still lives in his 1,300-square-foot split-level childhood home. He started at Koch Foods when it was a one-room butcher shop, lured by a 50% equity offer from original owner Fred Koch. He bought out his former boss in 1992 and expanded by snapping up smaller feed mills and slaughterhouses.
