When Jim Koch found out he had become a billionaire, it was his daughter who broke the news.
Her friends were confused. "Em, your dad's a billionaire? Why are you scooping ice cream for $7 an hour?" they asked her. She relayed the question to her dad, founder of The Boston Beer Co. the brewhouse behind Sam Adams beer.
"It was actually pretty funny because when it happened I didn't know," Koch said in an interview with CNBC at the Iconic conference in Boston last week. "You know, Forbes prints this thing and they don't notify you. But it got in the Globe and my daughter told me."
