Nathan Blecharczyk and Greg Hayes are two well-known American business figures, but they come from very different industries. Blecharczyk is a co-founder of Airbnb, the online travel and home-sharing company. Hayes is the former chief executive of RTX, formerly Raytheon Technologies, one of the largest aerospace and defense companies in the world. Many people type both names into a search engine at once, and this guide explains who each man is and what is actually known about any link between them.
Is There a Connection Between Nathan Blecharczyk and Greg Hayes?
The first thing to say is that no public record shows a business partnership, shared company, or personal relationship between the two men. Blecharczyk’s career has been tied to Airbnb since 2008, while Hayes spent more than two decades at United Technologies and then led RTX. Their companies operate in separate sectors, and neither man sits on the board of the other’s company.
A search for both names together often returns pages that mix unrelated stories or sound more certain than the facts allow. Some of these pages are low-quality content that pairs well-known names to catch search traffic. The more useful way to understand the two men is to look at each career on its own, and the sections below do that using company filings, official biographies, and reliable business reporting.
Who Is Nathan Blecharczyk?
Nathan Blecharczyk was born in 1983 and grew up in the Boston area. He attended Boston Latin Academy before going on to Harvard University, where he earned a degree in computer science. He was also an entrepreneur while still in high school, running a software business that sold to clients in more than 20 countries.
After Harvard, Blecharczyk worked as an engineer at several technology companies, including Microsoft, OPNET Technologies, and Batiq. His path changed when he moved into an apartment in San Francisco with Joe Gebbia, whom he had known from Boston. Gebbia was then working with Brian Chesky on a new idea, and Blecharczyk joined them as the technical builder behind it.
How Airbnb Began
The three men started the website in August 2008, and it grew out of a simple idea about renting out spare space to travelers. The company was accepted into the startup program Y Combinator in 2009, which helped it find investors and grow beyond its early days. As the founding engineer, Blecharczyk built the first version of the platform and later led the teams that handled engineering, data science, payments, and performance marketing.
Airbnb became a public company in December 2020, and it now describes itself as a platform with millions of hosts around the world. Bloomberg’s wealth index reports that the company has welcomed more than two billion guests since it was founded. Its most recent annual revenue figures cited by Bloomberg were above eleven billion dollars for 2024.
Blecharczyk’s Role at Airbnb Today
Blecharczyk was the company’s first chief technology officer. In early 2017 he moved into the role of chief strategy officer, which he still holds. In October 2017 he was also named chairman of Airbnb China, the company’s local business in that market.
Airbnb’s 2026 proxy statement lists him as chief strategy officer, co-founder, and director, and gives his age as 42. Company biographies explain that he leads work that needs a broad view of the business, public policy, product, and data. Examples of projects he has overseen include tools that help cities manage short-term rentals and technology that screens reservations to reduce risky bookings.
Giving, Family, and Public Life
In June 2016, Blecharczyk, Chesky, and Gebbia signed the Giving Pledge, the campaign started by Warren Buffett and Bill Gates in which wealthy individuals promise to give away most of their wealth. Blecharczyk is married to Elizabeth Morey Blecharczyk, a neonatologist, and the couple have two children and live in San Francisco. He serves on the board of Common Sense Media, and he and his wife have said they enjoy hosting guests through Airbnb themselves.
Bloomberg’s billionaire ranking places his wealth at a little over nine billion dollars, with most of it tied to his Airbnb shares. Figures like this move with the stock market, so they should be treated as a snapshot instead of a fixed number.
Who Is Greg Hayes?
Gregory J. Hayes was born around 1960 and grew up in Williamsville, New York, near Buffalo. He began college at Cornell University, where he played football and studied pre-law for a year, and he soon decided law was not the right path. He transferred to the Krannert School of Management at Purdue University and graduated in 1982 with a degree in economics. He is also a certified public accountant, and he has said that becoming the chief financial officer of a major company was his goal after he left public accounting.
Hayes’s Rise at United Technologies
Hayes joined United Technologies in 1999 when it merged with Sundstrand Corporation, where he had been a finance executive. Over the following years he held a series of finance and accounting roles, including controller in 2003. In 2008 he became chief financial officer, a position he held until 2014. On November 23, 2014, the board named him president and chief executive officer after Louis Chênevert retired, and he became chairman in 2016.
As chief executive, Hayes reshaped the company from a broad industrial group into a focused aerospace business. He sold the helicopter maker Sikorsky Aircraft in 2015 and bought Rockwell Collins in 2018. In 2020 the elevator business Otis and the heating and cooling business Carrier were spun off as separate companies.
Creating RTX and Stepping Aside
The biggest move of his career came in April 2020, when United Technologies merged its remaining aerospace businesses, Pratt & Whitney and Collins Aerospace, with Raytheon Company. The result was Raytheon Technologies, which was later renamed RTX. Hayes became chief executive of the new company and was elected chairman in 2021.
On May 2, 2024, Christopher Calio took over as chief executive and Hayes became executive chairman. In February 2025 the company announced that Calio would also become chairman effective April 30, 2025, and that Hayes would leave the board and serve as a special adviser to Calio through January 2, 2026. Hayes had also joined the board of Nucor, the steel producer, back in 2014 while he was still chief financial officer.
Comparing the Two Leaders
The two men took very different paths to the top of their organizations. Blecharczyk is a founder who helped create a company from nothing and has stayed with it for nearly two decades, while Hayes is a career finance executive who rose through an established company and then led a major merger. One built technology that changed how people travel, and the other guided one of the largest defense and aerospace groups in the world.
They also share some traits that explain why both names draw attention. Each held a senior role at a company that is closely watched by investors and the press, and each is known for a strong grasp of numbers, one as an engineer and the other as an accountant. Neither approach is better than the other, and both show that large companies are led by people with very different strengths.
Why People Search for Both Names
There are a few likely reasons the two names appear together in search results. Business news sites often list executives from different industries in the same roundup, and some content websites combine famous names in a single headline to attract clicks. A reader may also have seen both men mentioned in articles about corporate leadership, wealth, or board changes and wanted to compare them.
If you are looking for a direct link, the honest answer is that none has been confirmed. The best sources for the latest facts are Airbnb’s investor and news pages, RTX’s investor relations site, and regulatory filings, which are updated as roles change.
