My wife of 30 years is Chinese although born in Vietnam. She knows the owner of Huy Fong who also is ethnic Chinese from Vietnam. He started in a small space in LA's Chinatown and become so successful that eventually he built a large manufacturing facility where they also produce other styles of hot sauce.

My wife and her family own several large Asian supermarkets in Los Angeles and Orange counties where Sriracha of course is a big seller. It's always in the house, and my kids grew up on it.
