When Asian Americans were largely excluded from labor markets in the 19th century, they started their own businesses. They have started convenience and grocery stores, professional offices such as medical and law practices, laundries, restaurants, beauty-related ventures, hi-tech companies, and many other kinds of enterprises, becoming very successful and influential in American society. They have dramatically expanded their involvement across the American economy. Asian Americans have been disproportionately successful in the hi-tech sectors of California's Silicon Valley, as evidenced by the Goldsea 100 Compilation of America's Most Successful Asian Entrepreneurs.
