Nathan Blecharczyk and Greg Hayes have no documented connection of any kind. They have never worked together, never invested together, never sat on the same board, and are not related. One built a software platform that changed how the world sleeps away from home. The other ran the largest aerospace and defence company on the planet. Nothing in the reliable record joins them, and this article will not invent a link that does not exist.
Blecharczyk is the technical co-founder of Airbnb, the engineer who coded its first website and who now serves as its chief strategy officer. Hayes is the former chairman and chief executive of RTX, the company created when he merged United Technologies with Raytheon in 2020. Their stories are worth reading side by side for the contrast alone: a startup written in code by three young men in a San Francisco apartment, and an industrial giant assembled by merger at the age of spreadsheets and boardrooms.
Here is who each of them is, what each actually did, and what the public record does and does not show.

Who Is Nathan Blecharczyk?
Nathan Blecharczyk was born in 1983 in Boston, Massachusetts, the son of Sheila and Paul Steven Blecharczyk. The family is Polish American, and his ancestors came to the United States around the time of the First World War. Boston stayed at the centre of his story: he attended Boston Latin Academy, one of the city’s famous public schools, and graduated in 2001.
He was an entrepreneur before he was legally an adult. While still at high school he ran a web hosting and software business with clients in more than twenty countries, and he earned enough from it to pay his own tuition at Harvard University. He kept writing programs through college, worked on the business staff of the student newspaper, The Harvard Crimson, and shut the hosting business down in 2002 to concentrate on his studies. He graduated in 2005 with a Bachelor of Science degree in computer science.
His first conventional job was as an engineer at OPNET Technologies, a network software company. It did not hold him for long. He moved to San Francisco, became the roommate of a young designer named Joe Gebbia, and in 2008 became a founder himself, joining Gebbia and Brian Chesky in the small venture that became Airbnb.
The idea itself was born of rent money. During a design conference in San Francisco in October 2007, when every hotel room in the city was sold out, Chesky and Gebbia rented three air mattresses on their apartment floor to visiting designers. The experiment, first called AirBed and Breakfast, suggested something larger: that ordinary people with spare space could be hosts, and that travellers might prefer a stranger’s home to a hotel. What the idea needed was a platform that could handle listings, payments and trust at scale. That was Blecharczyk’s job, and the company they formally built together in 2008 still runs on the foundation he wrote.
Blecharczyk: Building Airbnb and Surviving 2020
Every founding team divides its labour, and Blecharczyk’s share was the machine itself. He was Airbnb’s first chief technology officer and coded the company’s original website personally, using the Ruby on Rails framework. As the platform grew from rented air mattresses during a design conference into a global marketplace, he built and led the teams behind its engineering, data science, payments and performance marketing, the invisible systems that let millions of strangers trust each other with their homes and their money. Few founders in modern business can say they wrote the first version of a product now used in almost every country on earth. He can.
In early 2017 he moved from the technology role to become Airbnb’s chief strategy officer, and that October he was also named chairman of Airbnb China, the company’s push into the largest travel market in the world. One of his later projects shows the strategy mind at work: the Airbnb City Portal, a software tool built for city governments, an attempt to give regulators data about short-term rentals instead of merely fighting them.
Then came the hardest year in the company’s life. When COVID-19 emptied the world’s calendars in the spring of 2020, Airbnb’s bookings collapsed within weeks. The company raised about $2 billion in emergency funding, and in May 2020 it cut roughly 1,900 jobs, about a quarter of its workforce. The turnaround that followed was just as fast: travellers chose whole homes over crowded hotels, bookings roared back, and in December 2020 Airbnb listed on the Nasdaq stock exchange in one of the largest American IPOs of the year. The programmer who had paid his college tuition from a teenage business was now a co-founder of a public company, and he remains its chief strategy officer in 2026.
The scale the platform reached is difficult to overstate. Airbnb now operates in more than 220 countries and regions, and its hosts have welcomed well over a billion guest arrivals since those three air mattresses in 2008. Blecharczyk’s own biography on the company’s investor site notes, almost as an aside, that he has personally stayed in hundreds of homes booked through the platform and hosts guests himself in San Francisco, a founder still using his own product nearly two decades on.

Who Is Greg Hayes?
Gregory J. Hayes was born in 1960 or 1961; his exact birth date has never been published in authoritative sources, a small reminder that senior industrial executives could once keep such details private. He grew up in Williamsville, New York, spent a year at Cornell University, where he played football and started in pre-law, then transferred to Purdue University, graduating from its Krannert School in 1982 with a bachelor’s degree in economics. He qualified as a certified public accountant.
Hayes joined United Technologies Corporation in 1999, arriving through its acquisition of the Sundstrand Corporation, and spent the next fifteen years climbing the finance and strategy ladder. He served as the company’s chief financial officer from 2008 to 2014, through the financial crisis, and in November 2014 he became its chief executive, adding the chairmanship in September 2016.
His formation explains his style. Accountant chief executives are rare at the top of industrial companies, and Hayes ran United Technologies as a numbers-first operator: a portfolio manager of businesses as much as a manager of factories. As chief financial officer he had already helped steer the $18 billion acquisition of the aerospace supplier Goodrich, completed in 2012, and the pattern of his later career, buying, selling and separating whole divisions, was set in those finance years.
Hayes: The Merger That Created RTX
Hayes’s decade at the top was defined by reshaping his company rather than merely running it. In 2015 he sold the Sikorsky helicopter business to Lockheed Martin. In 2018 he completed the acquisition of Rockwell Collins, the largest deal in the company’s history to that point, creating the Collins Aerospace business. Then he made the move that defines his career: a merger of equals between United Technologies and the Raytheon Company, closed on 3 April 2020. In the same week the group’s Otis elevator and Carrier air conditioning businesses were spun off as separate companies, and the remaining aerospace and defence giant took the name Raytheon Technologies. Hayes was elected chairman of the combined board in 2021, and in 2023 the company shortened its name to RTX.
The timing could hardly have been harsher. The merger closed days after the pandemic grounded the world’s airlines, the customers of half his new company. Hayes steered the combined group through that collapse in air travel while integrating two huge engineering cultures, and he handed over a stabilised company: he retired as chief executive on 2 May 2024, succeeded by Christopher Calio, stayed as executive chairman until 30 April 2025, and finished a special advisor role at the start of January 2026.
Retirement has not ended his board career. Since March 2025 he has been a director of BD, the medical technology company, he remains a director of the energy company Phillips 66, and he chairs the board of NAF, the education nonprofit formerly known as the National Academy Foundation.

The Connection Question
Is there any real connection between Nathan Blecharczyk and Greg Hayes? On the public record, none at all. The standard checks come back empty in every direction. They have never worked for the same company: Blecharczyk has spent his whole career in software and at Airbnb, Hayes spent his in industrial finance and aerospace. They share no boardroom: Airbnb and the education media nonprofit Common Sense Media on one side, BD, Phillips 66 and NAF on the other. No investment, deal, panel, award or news report places them in the same room, and there is no personal or family relationship between them.
The pairing exists because search engines and comparison sites put prominent names together, not because the men have any history together. If their names appear side by side online, that is the whole explanation.
What they genuinely share is a theme, and it is an interesting one. Both are builders of platforms that other people depend on: his software platform connects millions of hosts and guests, Hayes’s industrial platform connected two centuries-old engineering companies into one. Both are operators rather than celebrities, men whose work is mostly invisible when it goes well. And both had their defining leadership test in the same spring of 2020, when the pandemic attacked travel from both ends at once, emptying Airbnb’s rooms and grounding the airlines RTX supplied.
Personal Lives
Blecharczyk’s family life is documented in outline. He is married to Dr Elizabeth Morey Blecharczyk, a neonatal hospitalist and clinical instructor in paediatrics at Lucile Packard Children’s Hospital at Stanford, who cares for newborn babies. The couple live in San Francisco, are hosts on Airbnb themselves, and have welcomed hundreds of guests over the years, according to the company’s own biography of him. In June 2016 the couple signed the Giving Pledge, committing to give away the majority of their wealth. Their letter described giving interests that were, in their words, quite broad:
“Education, scientific research, medicine, space exploration, conservation of the planet and more effective governance.”
The pledge has produced concrete gifts close to home: in 2019 he gave $1 million to Boston Latin Academy, his old school, and pledged a further $1 million in matching gifts, and in 2022 the couple committed to match up to $10 million in donations to Airbnb.org to house refugees fleeing the war in Ukraine. Their children are kept out of public profiles, and this article follows that choice.
Hayes’s personal life is documented even more thinly. Mainstream profiles record that he is married, and his wife and family are not named in them. For a man who ran a company of well over a hundred thousand employees, his private footprint is remarkably small, and what is public about him is his work: the finance career, the merger, and the board seats he holds now.
What They Share, and What They Do Not
Set side by side, the two careers rhyme in clear ways:
- Both built or rebuilt platforms at global scale, one in software and one in heavy industry.
- Both are working operators rather than public personalities, rarely in the spotlight their positions could command.
- Both faced their defining crisis in 2020 and came through it with their companies transformed rather than broken.
- Both started at the bottom of their trades, he writing code for his own teenage business, Hayes as an accountant in an acquired subsidiary.
The differences are just as clear:
- Blecharczyk is a founder who still works at the company he created; Hayes was a professional manager who rose inside a company founded generations before him.
- Blecharczyk’s world is consumer technology and hospitality; Hayes’s is aerospace, defence and industrial finance.
- Blecharczyk is still in his executive role in 2026; Hayes has completed his, moving to board seats in 2024 and 2025.
- They have never worked together, share no board, and have no documented meeting or personal link of any kind.

Frequently Asked Questions
Did Nathan Blecharczyk and Greg Hayes ever work together?
No. There is no record of them working together, investing together, or sitting on the same board. Blecharczyk has spent his career in software and at Airbnb, which he co-founded in 2008. Hayes spent his career at United Technologies and RTX. Their industries, travel technology and aerospace, simply do not intersect in any documented way.
Are Nathan Blecharczyk and Greg Hayes related?
There is no evidence of any family relationship, and no reliable source suggests one. Blecharczyk’s family is Polish American and rooted in Boston. Hayes grew up in Williamsville, New York. The two names are paired online by search engines and comparison sites, not by any real connection.
Is Greg Hayes still the CEO of RTX?
No. Hayes retired as chief executive of RTX on 2 May 2024 and was succeeded by Christopher Calio. He remained executive chairman until 30 April 2025 and finished a special advisor role in January 2026. In 2026 he is a director of BD and Phillips 66 and chairman of the education nonprofit NAF.
What does Nathan Blecharczyk do at Airbnb now?
He is Airbnb’s chief strategy officer, a role he took in early 2017 after serving as the company’s first chief technology officer, and he is also chairman of Airbnb China. He leads major strategic initiatives across the business and serves on the board of the nonprofit Common Sense Media.
Did Greg Hayes found RTX?
Not in the startup sense, but he created it. As chief executive of United Technologies he engineered its merger of equals with Raytheon, which closed on 3 April 2020 and formed Raytheon Technologies, renamed RTX in 2023. He had earlier completed the Rockwell Collins acquisition and the sales and spin-offs that reshaped the group.
Why are Nathan Blecharczyk and Greg Hayes searched together?
Because comparison sites and search suggestions pair prominent business names, and both men are well-known, relatively private operators who led their companies through the pandemic. There is no event, deal or relationship behind the pairing, only that shared profile.
Conclusion
Nathan Blecharczyk and Greg Hayes are not connected by a company, a boardroom or a family tree, and this article has not pretended otherwise. One wrote the first code for a platform that changed travel and has guided its strategy ever since. The other spent a decade taking an industrial giant apart and putting it back together as RTX.
Read together, they show two very different ways of building at scale: writing the thing yourself, line by line, or assembling it, merger by merger. That contrast, and nothing more personal, is why their names travel together.
