Masayoshi Son: Early Life and Education
Masayoshi Son was born on August 11, 1957, in Japan. He developed an interest in technology and business during his early years. Later, he moved to the United States to continue his education and explore opportunities in the growing technology sector.
Son attended the University of California, Berkeley, where he studied economics. During his university years, he became interested in computers and the commercial possibilities of emerging technology. In particular, the rapid development of personal computers influenced his decision to build a business in this field.
After completing his education, Son returned to Japan with plans to establish his own company. This decision eventually led to the creation of one of the country’s most recognised technology businesses. His educational experience and international exposure helped shape his approach to entrepreneurship.
Masayoshi Son’s Business Career and SoftBank
In September 1981, Son founded Nihon SoftBank, which later became SoftBank Group. Initially, the company focused on distributing packaged computer software in Japan. However, Son gradually expanded its business activities as the technology market developed.
During the 1990s, SoftBank increased its involvement in internet-related businesses. In 1996, Son became president and CEO of Yahoo Japan, which helped strengthen his position in the growing digital economy. Furthermore, SoftBank entered the telecommunications market through its acquisition of Vodafone Japan in 2006.
Another major milestone came in 2016 when SoftBank acquired ARM, a leading semiconductor technology company. This investment strengthened SoftBank’s position in the global technology industry. Son also established the SoftBank Vision Fund, which provided investment capital to technology businesses around the world.
As a result, his career became closely associated with major investments in technology, telecommunications, artificial intelligence, and other developing industries.

Hayes earned a bachelor’s degree in economics from Purdue University. He also became a Certified Public Accountant, giving him a professional foundation in accounting and financial management. These qualifications later supported his work in senior corporate positions.
In 1999, Hayes joined United Technologies Corporation through its merger with Sundstrand Corporation. Over time, he took on several important responsibilities within the organisation.

In 2014, United Technologies appointed Hayes as its chief executive officer. Two years later, he also became chairman. His leadership focused on reshaping the company’s business portfolio and strengthening its position in the aerospace industry.
For example, United Technologies sold Sikorsky Aircraft in 2015 and acquired Rockwell Collins in 2018. Later, the company separated its Otis and Carrier businesses in 2020. These changes formed part of a wider strategy to focus the remaining organisation on aerospace operations.
One of Hayes’s most important achievements came in 2020. He led the merger of United Technologies’ remaining aerospace businesses, Pratt & Whitney and Collins Aerospace, with Raytheon Company. Consequently, the transaction created Raytheon Technologies, which later adopted the name RTX.
Hayes served as RTX’s chief executive before becoming executive chairman in May 2024. He stepped down from the executive chairman role in April 2025.
