Masayoshi Son and Greg Hayes: Is There a Business Connection?
One of the most interesting questions about Masayoshi Son and Greg Hayes concerns their professional relationship.
Despite their influence in international business, available corporate biographies and company records do not establish a direct partnership between them.
There is no verified public announcement showing that they jointly founded a company, managed a shared investment, or served together on the same corporate board.
Their careers developed through separate organizations.
Masayoshi Son is associated with SoftBank Group, Arm, and technology investments. Greg Hayes built his career through United Technologies, RTX, and other corporate leadership positions.
However, the absence of a documented partnership does not prove that the two executives have never met or communicated privately.
Why Are Their Names Discussed Together?
There are several reasons their names can appear together in business discussions.
First, both executives have managed large multinational organizations. Their decisions have influenced employees, investors, customers, and entire industries.
Second, both have participated in major corporate transactions. Son became known for technology investments and acquisitions, while Hayes led significant aerospace restructuring and mergers.
Finally, their careers demonstrate how leadership can shape industries during periods of technological change.
Therefore, comparing their achievements makes sense. However, it is important not to confuse a professional comparison with evidence of a personal or business relationship.
Masayoshi Son vs. Greg Hayes: Key Differences
Although both men have held senior leadership positions, their professional responsibilities and business strategies differ considerably.
| Category | Masayoshi Son | Greg Hayes |
|---|---|---|
| Nationality | Japanese | American |
| Main company | SoftBank Group | United Technologies and RTX |
| Industry | Technology and investment | Aerospace and defense |
| Education | University of California, Berkeley | Purdue University |
| Career background | Entrepreneur and investor | Accountant and corporate executive |
| Major achievement | Building SoftBank and major technology investments | Helping establish RTX |
| Business focus | AI, semiconductors, and technology | Aerospace, engineering, and defense |
| Leadership approach | Long-term technology investment | Corporate restructuring and operations |
| Known role | Founder and CEO | Former CEO and chairman of RTX |
The comparison highlights their different strengths.
Son has concentrated on identifying future technology opportunities. Hayes focused on managing established industrial businesses and improving their long-term structure.
Neither approach is automatically better. Their effectiveness depends on the industries, risks, and business goals involved.
Masayoshi Son’s Focus on Artificial Intelligence
Artificial intelligence has become a central part of SoftBank’s business strategy.
Son believes AI will transform industries such as healthcare, manufacturing, transportation, communication, and computing.
His company has therefore increased its investments in businesses and infrastructure connected to advanced AI systems.
SoftBank’s Investment in OpenAI
One of SoftBank’s major recent developments involves its investment in OpenAI.
On February 27, 2026, SoftBank announced a planned additional investment of $30 billion through SoftBank Vision Fund 2.
The company completed the three investment tranches by October 1, 2026. Following those investments, SoftBank reported cumulative OpenAI investments of $64.6 billion and an ownership interest of approximately 13%.
These figures come from SoftBank’s corporate announcements.
The investment reflects Son’s ambition to expand SoftBank’s position in artificial intelligence and support the development of advanced computing technologies.
However, large investments also carry financial risks. Their eventual returns depend on company performance, market conditions, competition, and future technological developments.
Why Arm Matters to Son’s Strategy
Arm is another important part of SoftBank’s technology strategy.
The company designs semiconductor architectures used in many smartphones, computers, and other electronic devices.
Arm’s technology has become increasingly relevant as demand grows for efficient computing systems.
For Son, the semiconductor industry offers opportunities connected to AI, cloud computing, robotics, and data centers.
This strategy shows how SoftBank aims to participate in several layers of the technology industry rather than relying on one business sector.
Greg Hayes and the Transformation of RTX
Greg Hayes made his most significant corporate contribution through the development of RTX.
In 2020, United Technologies combined its aerospace businesses with Raytheon Company. The transaction created Raytheon Technologies, which later adopted the RTX name.
The company brought together three major business areas:
- Collins Aerospace: Develops aircraft systems, avionics, and aerospace technologies.
- Pratt & Whitney: Produces aircraft engines and related propulsion systems.
- Raytheon: Develops defense systems, missiles, sensors, and other advanced technologies.
This combination created a major organization serving commercial aviation and defense customers.
Greg Hayes’s Leadership Transition
Hayes served as RTX’s president and CEO following the 2020 merger.
In May 2024, Christopher Calio succeeded him as president and CEO. Hayes then continued as executive chairman.
In February 2025, RTX announced that Hayes would step down as executive chairman and leave the board effective April 30, 2025.
He subsequently served as a special adviser to the RTX CEO through January 2, 2026.
Therefore, Hayes should not be described as RTX’s current CEO or chairman.
What Does Greg Hayes Do Now?
His corporate responsibilities have continued beyond RTX.
As of November 2026, publicly available corporate information identifies Hayes as a director of Becton, Dickinson and Company and lead independent director of Phillips 66.
These positions allow him to contribute his experience in corporate governance, financial oversight, strategic planning, and executive leadership.
His transition from a major operating role to corporate board positions represents a different stage of his business career.
