Introduction
Masayoshi Son and Greg Hayes are well-known business leaders who have made significant contributions to different areas of the global economy. Masayoshi Son is a Japanese entrepreneur and investor recognized for building SoftBank into a major technology and investment group. Greg Hayes, meanwhile, is an American corporate executive known for his leadership at United Technologies Corporation (UTC) and RTX.
Although Masayoshi Son and Greg Hayes are sometimes discussed together in online searches, their professional backgrounds and business activities are quite different. There is no publicly documented evidence that they are relatives, direct business partners, or colleagues who managed the same company. Their names are connected mainly through separate business stories that attracted attention in the United States in December 2016.
During that period, Son announced a substantial investment plan for the United States, while Hayes was involved in discussions about manufacturing jobs at Carrier’s Indiana facility. Understanding these events helps explain why the two executives are sometimes mentioned together.
Who Is Masayoshi Son?
Masayoshi Son is a Japanese entrepreneur, investor, and the founder of SoftBank Group. Born on August 11, 1957, he developed a reputation for making ambitious investments in technology and identifying opportunities in emerging industries.
Son established the business that eventually became SoftBank in 1981. What began as a software distribution business expanded over time into telecommunications, internet services, investment funds, semiconductor technology, and artificial intelligence.
He studied economics at the University of California, Berkeley, before returning to Japan to pursue his business ambitions. Throughout his career, Son has been associated with major investments in companies such as Alibaba and Arm, as well as significant investments connected with OpenAI.
His approach often involves committing substantial capital to technologies he believes will shape the future. Artificial intelligence, advanced computing, and semiconductor infrastructure have become particularly important to SoftBank’s long-term strategy.
When comparing Masayoshi Son and Greg Hayes, one important distinction is that Son built his reputation primarily as a company founder and investor rather than as an executive who advanced through an established industrial corporation.
Who Is Greg Hayes?
Gregory J. Hayes is an American business executive recognized for his leadership at United Technologies Corporation and RTX. Unlike Son, Hayes developed his career through financial, operational, and executive positions within large corporations.
Hayes joined United Technologies in 1999 following its merger with Sundstrand. He subsequently held several senior positions involving finance, planning, and corporate strategy. In 2014, he became CEO of United Technologies, later taking on the role of chairman in 2016.
He earned a bachelor’s degree in economics from Purdue University and is a Certified Public Accountant. His financial background helped shape his approach to corporate management, including acquisitions, restructuring, and operational efficiency.
One of Hayes’s most significant career developments occurred when United Technologies’ aerospace businesses combined with Raytheon Company in 2020. The resulting organization became Raytheon Technologies and was later renamed RTX.
Hayes served as chairman and CEO of RTX before transitioning away from executive leadership. He stepped down as executive chairman and left the company’s board in April 2025. By 2026, his professional activities included corporate governance and board responsibilities, including roles at Phillips 66 and Becton, Dickinson and Company.
What Connects Masayoshi Son and Greg Hayes?
The main connection between Masayoshi Son and Greg Hayes is historical rather than personal or professional. Their names became indirectly associated because both were involved in prominent American business discussions during December 2016.
Son was promoting a major investment commitment intended to support businesses and employment in the United States. Hayes, on the other hand, was dealing with a manufacturing controversy involving Carrier, which was then owned by United Technologies.
These events concerned investment, employment, industrial competitiveness, and the economic priorities of the incoming U.S. administration. However, they involved separate companies and different business objectives.
There is no reliable public evidence establishing that Masayoshi Son and Greg Hayes jointly operated a business, served on the same corporate board, or participated in a shared venture. Their simultaneous appearance in business coverage does not establish a direct relationship.
The December 2016 Investment and Jobs Stories
In December 2016, Masayoshi Son met then-President-elect Donald Trump and announced plans for SoftBank to invest approximately $50 billion in the United States. The announcement was associated with technology businesses and expectations of supporting tens of thousands of American jobs.
Around the same time, Greg Hayes was dealing with a separate issue involving Carrier’s plans to move manufacturing jobs from Indiana to Mexico.
Donald Trump publicly pressured United Technologies and Carrier to retain jobs in Indiana. Following negotiations, an arrangement allowed hundreds of positions to remain in Indianapolis. Carrier also planned to invest approximately $16 million in the facility.
However, Hayes explained that some of the investment would support automation. Although automation can improve productivity and manufacturing efficiency, it can also reduce the number of workers needed for particular tasks.
The contrast between these events explains why Masayoshi Son and Greg Hayes may appear together in discussions about business and employment. Son represented investment in technology, while Hayes was dealing with manufacturing costs and factory operations.
Different Careers and Leadership Styles
The professional paths of Masayoshi Son and Greg Hayes demonstrate two different approaches to business leadership.
Son is known for his ambitious investment strategy and willingness to make large financial commitments based on expectations about future technology. His career includes major successes as well as costly investment setbacks. In 2026, he continues to lead SoftBank, with artificial intelligence and advanced computing among its central priorities.
Hayes built his reputation through corporate finance, acquisitions, restructuring, and executive management. During his time at United Technologies, the company sold Sikorsky Aircraft, acquired Rockwell Collins, and separated Carrier and Otis into independent businesses. The aerospace merger with Raytheon was another major development during his leadership career.
While Son concentrates on identifying and financing emerging technological opportunities, Hayes’s career has been more closely associated with managing established industrial and aerospace businesses.
These differences make it misleading to describe Masayoshi Son and Greg Hayes as business partners simply because their professional stories overlap in historical news coverage.

Their names became associated through separate events in December 2016 involving American investment plans and manufacturing employment.
Son built SoftBank into a major technology and investment group and continues to focus on AI and advanced computing. Hayes established his reputation through leadership at United Technologies and RTX before moving into corporate governance.
Ultimately, Masayoshi Son and Greg Hayes represent two different approaches to business success. One is a founder and technology investor, while the other is an experienced corporate executive. Their shared place in business history comes from the economic issues surrounding their work, rather than any confirmed personal connection or joint enterprise.
