Clayton Lee “Clay” Mathile (pronounced [Muh-til]), born January 11, 1941, is an American entrepreneur, investor and philanthropist, best known for leading The Iams Company, to nearly $1 billion in sales before selling it to Procter & Gamble for $2.3 billion in 1999 in what was, at the time, the largest cash-only deal in P&G’s history. Mathile shared some of the proceeds with 2,000 Iams employees.
In 1970, dissatisfied with corporate life, Mathile accepted a job as sales manager at a small, regional pet food manufacturer: The Iams Food Company in Dayton, Ohio. Over time, he became the company’s sole owner, CEO, and chairman. Known for his commitment to developing products that delivered superior nutrition, Mathile also emphasized innovative marketing. He is one of the few entrepreneurs to lead a company with two successful premium brands — Iams and Eukanuba.
