Career & Education – Company, University, & College

Masayoshi Son’s career is one of the most remarkable entrepreneurial journeys in modern business history. From selling a translation device as a college student to building a $166 billion technology empire, his story spans over four decades of bold investments and relentless ambition.

Masayoshi Son Career Timeline

While studying at UC Berkeley in the late 1970s, the teenage Son invented a multilingual electronic translator, which he sold to Sharp Corporation for approximately $1 million. He also developed arcade game software used in cafeterias and restaurants, earning another $1 million. He then formed a company called Unison World, which he sold to ceramics and electronics company Kyocera for about $2 million.

After graduating in 1980, Son returned to Japan and founded SoftBank in 1981 as a software distribution company. The famous origin story recounts how Son stood on a crate in a small office and told his two part-time employees that the company would reach $75 million in sales and serve 1,000 dealer outlets within five years. Both employees quit, thinking he was delusional. Within 18 months, SoftBank had signed 200 dealer outlets.

In 1995, SoftBank went public and Son co-founded Yahoo! Japan. By 1999, SoftBank had become the world’s largest internet technology company. His most legendary investment came in 2000 when he put $20 million into a then-unknown Chinese startup called Alibaba — an investment that grew to approximately $75 billion by Alibaba’s 2014 IPO, making it the most profitable venture capital investment in history.
