Aitthipat Kulapongvanich (Thai: อิทธิพัทธ์ กุลพงษ์วณิชย์; RTGS: Itthiphat Kunlaphongwanit), or nickname Tob (Thai: ต๊อบ), is a Thai Chinese young billionaire based in Thailand.
A Thai movie, The Billionaire, has been produced about this man's story.
He is most well known for his product Tao Kae Noi, a fried seaweed snack, which is sold around the Asia-Pacific area.
As a young man, Kulapongvanich gained success at playing online games and winning tournament prizes. He invested his money into selling fried chestnuts, which became popular in Thailand. With this financial backing, he went on to create the product of packaged deep fried flavored seaweed, which quickly became successful in Thailand, and was exported to Indonesia, Japan, Taiwan, Singapore, and the United States.
