Nathan Blecharczyk and Greg Hayes built their careers in different corners of American business. Blecharczyk helped establish Airbnb and develop the technology behind its travel marketplace. Hayes rose through finance and corporate management before leading United Technologies and RTX, overseeing major changes in the aerospace and defense industry. Comparing their backgrounds offers a useful look at how founders and career executives reach senior leadership positions. This article examines their education, professional milestones, responsibilities, and current roles, while addressing the central question behind the pairing: whether there is an established connection between them.
Are Nathan Blecharczyk and Greg Hayes Connected?
The company biographies and announcements reviewed for this article do not establish a direct business partnership or family relationship between Nathan Blecharczyk and Gregory J. Hayes, the former RTX chief executive discussed here.
Their careers can be compared through their work in technology, strategy, and company development. However, describing them as collaborators would require evidence of a shared venture, investment, or project.
Nathan Blecharczyk: Building Airbnb’s Technical Foundation
Nathan Blecharczyk, also known as Nate, is an Airbnb co-founder and its Chief Strategy Officer. He holds a Bachelor of Arts degree in Computer Science from Harvard University.
His contribution to Airbnb extends beyond software development. The company credits him with establishing its engineering, data science, payments, and performance marketing teams. These functions support different parts of the business, from maintaining the platform to processing transactions and attracting customers.
Airbnb’s development also involved a gradual expansion of its offering. Its original Airbed & Breakfast service launched in 2008. In March 2009, the business adopted the Airbnb name and expanded beyond rooms to include apartments, entire homes, and vacation rentals. It became a publicly traded company in December 2020.
From Technical Teams to Business Strategy
Blecharczyk’s strategy responsibilities bring together product development, data, public policy, and the company’s long-term priorities. Several projects offer concrete examples of that work.
He oversaw the creation of Airbnb’s City Portal, a tool designed to help local governments understand and manage short-term rentals. He also oversaw reservation screening technology intended to identify potentially high-risk bookings.
Another initiative, Airbnb-friendly apartments, helps eligible renters host their homes. Together, these projects show how his responsibilities reach beyond the booking interface into safety, housing arrangements, and relationships with cities.
Greg Hayes: From Finance to Aerospace Leadership
Gregory J. Hayes earned a bachelor’s degree in economics from Purdue University and is a Certified Public Accountant. His professional foundation was in finance, accounting, corporate strategy, and business development.
Hayes joined United Technologies through its acquisition of Sundstrand Corporation in 1999. He served as UTC’s Chief Financial Officer from 2008 to 2014, then became Chief Executive Officer in 2014 and chairman in 2016.
Those appointments placed him in charge of a diversified industrial company. His subsequent decisions changed the businesses UTC owned and the industries on which it concentrated.
Reshaping United Technologies
Under Hayes, UTC sold Sikorsky Aircraft in 2015 and acquired Rockwell Collins in 2018. The Rockwell Collins transaction helped create Collins Aerospace through its combination with UTC Aerospace Systems.
In November 2018, UTC also announced its intention to separate into three independent companies. The plan would give Otis and Carrier their own corporate structures while leaving UTC focused on aerospace.
The Otis and Carrier separations took place in 2020. UTC’s remaining aerospace businesses, Pratt & Whitney and Collins Aerospace, then combined with Raytheon Company in April 2020. Hayes became CEO of the resulting company, then called Raytheon Technologies and now known as RTX.
This sequence is central to his career: he led an established group through acquisitions, divestitures, separations, and a major merger.
Nathan Blecharczyk and Greg Hayes Compared
The clearest distinction between their careers is how they entered senior leadership and the organizations they helped develop.
| Area | Nathan Blecharczyk | Greg Hayes |
|---|---|---|
| Main career association | Airbnb | United Technologies and RTX |
| Educational background | Computer science at Harvard | Economics at Purdue; CPA |
| Route to leadership | Company co-founder | Finance and management executive |
| Principal industry | Travel marketplace and technology | Aerospace and defense |
| Representative work | Technical teams, platform tools, strategic initiatives | Acquisitions, divestitures, restructuring, merger integration |
| Current notable position | Airbnb Chief Strategy Officer | Phillips 66 Lead Independent Director |
Blecharczyk’s record centers on developing capabilities within a company he helped establish. Hayes’s record centers on managing and reshaping large businesses with existing operations, products, and customers.
That difference also changes the practical meaning of strategy. At Airbnb, the projects associated with Blecharczyk address how a marketplace operates and interacts with hosts, guests, and governments. In Hayes’s UTC career, major strategic decisions determined which businesses belonged together and which should operate independently.
These are comparisons drawn from their documented responsibilities, rather than claims about their private management styles.
What Roles Do They Hold Now?
As of October 2026, Airbnb identifies Blecharczyk as its co-founder and Chief Strategy Officer. His official biography also lists his board service at Common Sense Media.
Hayes is Lead Independent Director of Phillips 66, an appointment that took effect on May 13, 2026. He originally joined the energy company’s board in July 2022. Phillips 66 also lists him as a director of Becton, Dickinson and Company.
Understanding Hayes’s RTX Departure
Hayes’s former RTX titles need to be read with their dates. Christopher Calio succeeded him as CEO on May 2, 2024, when Hayes became Executive Chairman.
Calio subsequently became chairman effective April 30, 2025. RTX’s transition announcement specified that Hayes would serve as Special Advisor to the CEO through January 2, 2026. Calling Hayes the current RTX CEO or chairman would therefore misstate his position.
