Immigrant. CEO. Billionaire.

Hamdi Ulukaya has built Chobani into a multibillion-dollar yogurt giant by meshing big-hearted values with hard-edged competition. How his brand of progressive capitalism offers a new leadership model for the 21st century.

Hamdi Ulukaya never planned to move to America, much less start a yogurt business that would make him a billionaire. Things so easily could have been different. He might have gone into Turkish politics or the family cheese-making business, perhaps even married the hometown girl who his mother claimed would be perfect for him. He thinks about it a lot.

Instead, Ulukaya got hauled in for questioning by the Turkish police one day, and his life went in another direction.

At the time, in the early 1990s, Ulukaya was studying political science at Ankara University. A Kurd who grew up raising sheep in the mountains of eastern Turkey, he had gravitated toward the contentious Kurdish-rights movement, attending demonstrations and publishing a politically minded newspaper. Though Ulukaya has always strongly disavowed violence and wasn’t involved with the extremist group the PKK, he nevertheless attracted the attention of the Turkish government, which then—as now—sometimes harshly cracked down on activists. Ulukaya knew people who had been taken by the authorities and simply never came back. Was he about to be jailed? Tortured? Killed?

More than two decades later, Ulukaya was in Twin Falls, Idaho, recalling that fraught era. The founder and CEO of the multibillion-dollar yogurt business Chobani was at the largest of his company’s three manufacturing plants, where he had assembled senior staff to go over plans for the next year and beyond. Ulukaya is a quiet man with oversize features and a subtle magnetism that’s occasionally punctured by an endearingly goofy high-pitched laugh. Unlike many CEOs, he radiates more warmth than authority, and his manner is unhurried, even when his schedule is hectic (his schedule is always hectic).
