Masayoshi Son and Greg Hayes are two prominent business leaders whose names have occasionally appeared together in searches and older U.S. business coverage. However, there is no documented evidence that they are relatives, business partners, colleagues, or members of the same company.
Their strongest connection comes from December 2016, when both were involved in separate stories about American jobs and investment. Son was discussing a massive U.S. investment pledge through SoftBank, while Hayes was dealing with the Carrier factory controversy in Indiana.

Who Is Masayoshi Son?
Masayoshi Son is a Japanese entrepreneur, billionaire investor, and the founder of SoftBank Group. He was born on August 11, 1957, and is 69 years old as of 2026.
Son founded the business that became SoftBank in 1981. Over the following decades, he transformed it from a software distributor into a global technology and investment group.
His career has been closely connected with telecommunications, artificial intelligence, internet companies, semiconductors, and venture capital. Major SoftBank investments have included companies such as Alibaba, Arm, and OpenAI.
Who Is Greg Hayes?
Gregory J. Hayes is an American corporate executive best known for his leadership at United Technologies Corporation and RTX.
Hayes joined United Technologies through its merger with Sundstrand in 1999. He held several senior finance and strategy positions before becoming CEO in 2014 and chairman in 2016.
His background differs considerably from Son’s. Hayes built his career inside established corporations rather than founding his own company.
He earned a bachelor’s degree in economics from Purdue University and is also a Certified Public Accountant.
What Really Connects Them?
There is no confirmed direct business relationship between Masayoshi Son and Greg Hayes.
Public corporate records do not show that they have managed a company together, served on the same board, created a joint venture, or participated in the same major transaction.
Their names became indirectly connected because both appeared in major U.S. business stories during December 2016.
Those stories concerned investment, manufacturing, employment, and the incoming U.S. administration, but they involved completely different companies.
The December 2016 Connection
In December 2016, Masayoshi Son met President-elect Donald Trump and announced plans for SoftBank to invest approximately $50 billion in the United States.
The investment plan was associated with technology businesses and was expected to support tens of thousands of American jobs.
At roughly the same time, Greg Hayes was handling another politically sensitive jobs issue involving Carrier, which was then owned by United Technologies.
Carrier had planned to move manufacturing jobs from Indiana to Mexico.
The Carrier Jobs Story
Greg Hayes became part of a national debate after Donald Trump pressured United Technologies and Carrier to keep jobs in Indiana.
A deal eventually allowed hundreds of positions to remain in Indianapolis.
Carrier also planned to invest about $16 million in the facility, but Hayes later explained that part of this money would fund automation.
That created a complicated situation because automation could improve productivity while reducing the number of employees needed at the factory.
Two Different Stories
The Son and Hayes stories shared a broad theme but were fundamentally different.
Son’s announcement focused on bringing investment capital into American technology companies.
Hayes was focused on manufacturing costs, factory operations, jobs, and automation.
Son represented an international investor promising new investment, while Hayes represented a major industrial corporation deciding how to keep production competitive.
That is why describing them as business partners would be misleading.
Were They Business Partners?
There is no reliable evidence that Masayoshi Son and Greg Hayes were ever business partners.
Son’s professional world largely revolves around SoftBank, technology investments, telecommunications, semiconductor companies, and artificial intelligence.
Hayes spent his career working within major American industrial and aerospace corporations.
Their careers occasionally touched similar economic topics, but they did not follow the same corporate path.
No publicly documented company connects the two men directly.
Masayoshi Son’s SoftBank Career
Masayoshi Son established the predecessor of SoftBank in 1981.
He gradually expanded the company into telecommunications, internet services, investment funds, semiconductor technology, and artificial intelligence.
One of his most famous investments was SoftBank’s early backing of Alibaba. SoftBank later acquired Arm, one of the world’s most important semiconductor architecture companies.
Son also created the massive SoftBank Vision Fund to invest in technology businesses worldwide.
Son’s AI Strategy
Artificial intelligence has become one of Masayoshi Son’s biggest areas of focus.
SoftBank has increasingly concentrated its strategy around AI infrastructure, semiconductor technology, data centers, and advanced computing.
The company has also made enormous investments connected with OpenAI.
Son frequently discusses the potential development of artificial superintelligence, which he believes could eventually exceed human intellectual abilities across many areas.
His willingness to make enormous technology bets remains central to his business reputation.
Greg Hayes at United Technologies
Greg Hayes followed a more traditional corporate career.
He worked through finance, accounting, planning, and strategy roles at United Technologies before becoming its CEO.
During his leadership, UTC underwent major structural changes.
The company sold Sikorsky Aircraft, acquired Rockwell Collins, and later separated Carrier and Otis into independent companies.
These decisions significantly changed the structure and direction of one of America’s largest industrial corporations.
The Creation of RTX
One of Hayes’s most important career developments came in 2020.
United Technologies’ aerospace businesses merged with Raytheon Company to create Raytheon Technologies Corporation.
The company was later renamed RTX.
Hayes became Chairman and CEO of the newly combined organization, putting him in charge of one of the world’s largest aerospace and defense companies.
He remained an important figure at the company until his executive transition began.
Where Greg Hayes Is Now
Greg Hayes is no longer CEO of RTX.
Christopher Calio became President and CEO in May 2024, while Hayes moved into the Executive Chairman role.
Hayes later stepped down as Executive Chairman and left the RTX board in April 2025.
He subsequently served as a special adviser during the leadership transition.
By 2026, Hayes had moved primarily into corporate board and governance roles.
Greg Hayes’s Current Roles
Greg Hayes currently serves as Lead Independent Director at Phillips 66.
He also serves on the board of Becton, Dickinson and Company.
These positions represent a shift from managing large corporations every day toward advising and overseeing them from the boardroom.
His extensive experience with mergers, restructuring, finance, and executive leadership makes him valuable in corporate governance positions.
What Masayoshi Son Is Doing Now
Masayoshi Son remains actively involved in SoftBank.
Unlike Hayes, who has stepped away from full-time executive leadership, Son continues to guide his company’s long-term strategy.
His main focus is now artificial intelligence and advanced computing.
SoftBank has committed enormous amounts of capital to AI-related projects and companies.
Son believes the next major technological transformation will be driven by increasingly capable artificial intelligence systems.
Masayoshi Son Net Worth
Masayoshi Son is one of Japan’s wealthiest individuals.
Forbes estimated his fortune at roughly $80 billion in 2026, although billionaire net worth can change quickly because much of the wealth is connected with stocks and company valuations.
Son’s fortune has risen and fallen dramatically throughout his career.
Changes in SoftBank’s share price, Arm’s valuation, and major technology investments can significantly affect his estimated wealth.
Greg Hayes Net Worth
Greg Hayes’s exact net worth has not been officially confirmed.
Some websites publish estimates, but these numbers are usually calculated from stock holdings, executive compensation, or incomplete public information.
Reliable corporate filings provide clearer information about his salary and compensation than his total personal wealth.
While leading RTX, Hayes earned millions of dollars through salary, incentives, and equity awards.
However, executive compensation should not be confused with personal net worth.
Age and Education
Masayoshi Son was born on August 11, 1957, making him 69 years old in 2026.
He studied economics at the University of California, Berkeley before returning to Japan and beginning his entrepreneurial career.
Greg Hayes is approximately 65 years old in 2026 based on recent corporate filings.
He earned a bachelor’s degree in economics from Purdue University and later developed a strong career in corporate finance and accounting.
Family Background
Masayoshi Son comes from a family of four brothers.
His younger brother, Taizo Son, is also an entrepreneur and investor.
Son has occasionally spoken publicly about the influence of his father and his upbringing, although he generally keeps his immediate family away from constant media attention.
Greg Hayes is considerably more private about his family life.
Major corporate biographies provide very little information about his parents, siblings, wife, or children.
Height and Appearance
The exact heights of Masayoshi Son and Greg Hayes are not reliably documented in authoritative corporate biographies.
Several biography websites publish estimated measurements, but these should not be treated as confirmed facts.
Son usually appears in simple formal business clothing during corporate presentations and major technology events.
Hayes also maintains a traditional executive appearance, typically wearing formal suits during board meetings, investor presentations, and professional engagements.
Lifestyle
Masayoshi Son has accumulated enormous wealth, but his public image focuses more on business strategy than luxury living.
He is widely associated with ambitious investments, long-term technology predictions, and high-risk financial decisions.
Greg Hayes maintains an even more private public image.
Most information about him relates to corporate management, aerospace, financial strategy, and board responsibilities rather than personal possessions, homes, vehicles, or holidays.
Both executives maintain strongly business-focused public profiles.
Social Media Presence
Masayoshi Son has maintained a significant presence on X, where he has millions of followers.
He has used social media to comment on technology, society, business, and SoftBank-related developments.
Greg Hayes has a much quieter online presence.
He is primarily visible through professional networks such as LinkedIn and official corporate websites.
Neither man uses social media in the same way as entertainment celebrities or lifestyle influencers.
Leadership Styles
Masayoshi Son is known for a highly ambitious and future-focused leadership style.
He frequently makes large investments based on his expectations about how technology will develop over many years.
His strategy can involve considerable financial risk.
Greg Hayes developed a more operational and finance-driven leadership approach.
His major decisions involved acquisitions, divestitures, mergers, restructuring, and improving corporate performance.
The difference reflects their backgrounds: Son is a founder-investor, while Hayes built his career as a professional corporate executive.
Son and Rene Haas
One source of confusion around this keyword may be Rene Haas.
Rene Haas and Greg Hayes are completely different executives.
Rene Haas is CEO of Arm and has a genuine corporate relationship with Masayoshi Son through SoftBank’s ownership of Arm.
He has also held leadership responsibilities within the broader SoftBank organization.
Greg Hayes, by comparison, built his career at United Technologies and RTX and has no equivalent SoftBank role.
Interesting Facts
Masayoshi Son has led the business that became SoftBank for more than four decades.
His career includes enormous successes as well as costly investment setbacks, making him one of the most closely watched technology investors in the world.
Greg Hayes helped oversee one of the biggest transformations in American industrial business.
During his leadership years, UTC sold businesses, acquired new ones, separated Carrier and Otis, and merged its aerospace operations with Raytheon.
Both men became known for managing decisions worth billions of dollars.
Key Differences

Son founded his company and built his fortune through ownership and investments.
Hayes rose through the ranks of major corporations using his finance and management experience.

Their industries also differ, with Son focused largely on technology and AI and Hayes associated with aerospace, defense, and industrial management.

Their most notable connection comes from December 2016, when both men appeared in major U.S. business discussions involving jobs and investment.
Son was announcing a $50 billion U.S. investment plan, while Hayes was negotiating around Carrier manufacturing jobs in Indiana.
Nearly a decade later, their paths remain separate.

Greg Hayes has completed his executive leadership career at RTX and moved into corporate board positions.
The real connection between Masayoshi Son and Greg Hayes is therefore not a hidden partnership. It is an interesting overlap between two major business stories involving two very different leaders.
