Nathan Blecharczyk and Greg Hayes: Are They Connected?

Nathan Blecharczyk and Greg Hayes have no known business tie. Blecharczyk is an engineer who cofounded Airbnb in 2008 and still shapes its strategy. Hayes is an accountant who climbed through United Technologies, became its CEO in 2014, and later led RTX. Hayes has since retired from RTX and joined new company boards. Blecharczyk’s wealth is estimated near $9 billion, while Hayes’s disclosed holdings sit near $107 million. Both figures move with share prices. Treat them as snapshots. People often search both names together after seeing them in the same business roundup. Their companies do share one thing: both depend on air travel. Everything here comes from company filings, official bios, and reported results.

Bio at a Glance: Nathan Blecharczyk and Greg Hayes

Are Nathan Blecharczyk and Greg Hayes Connected?

Short answer: no. No filing, press release, or official bio ties them together. They have never run a company together. As far as public records show, neither has invested in the other’s business. Blecharczyk sits on Airbnb’s board. Hayes sits on the boards of BD and Phillips 66. Those boards do not overlap.

Where their worlds overlap

Air travel is the thread. Airbnb makes money when people book trips, and many of those trips involve a flight. RTX owns Pratt & Whitney, which builds jet engines. It also owns Collins Aerospace, which makes aircraft systems. So both companies rise and fall with travel demand.

2020 showed this clearly. Flights collapsed that spring. Airbnb cut about a quarter of its staff in May. Both companies also changed shape that year. RTX formed in April, and Airbnb went public in December.

Why some pages claim more

Some sites pair famous names because the pair gets clicks. They stretch thin facts into a story. If a page claims a deal or a friendship, look for a filing or a named source. If it cites none, move on. Investor pages and SEC filings settle most of these claims in minutes.

Who Is Nathan Blecharczyk?

Early life and education

Blecharczyk was born in 1983 and grew up in Boston. He attended Boston Latin Academy, one of the city’s public exam schools. He then earned a computer science degree at Harvard University in 2005.

He did not wait for graduation to start building. In high school, he ran a software business with customers in more than 20 countries, according to the World Economic Forum. After Harvard, he worked as an engineer at Microsoft, OPNET Technologies, and Batiq.

How Airbnb began

Blecharczyk found an apartment in San Francisco through a Craigslist ad and moved in with Joe Gebbia. Gebbia was already working with Brian Chesky on a plan to rent out air mattresses in their home. Blecharczyk joined as the technical cofounder. The website launched in August 2008.

Money was tight. During the 2008 presidential race, the founders sold cereal boxes with political themes to raise cash. Y Combinator, the startup accelerator, accepted Airbnb in 2009. That brought funding and advice. Blecharczyk wrote much of the original code, then built the engineering team.

His role today

Blecharczyk served as Airbnb’s first chief technology officer. In early 2017, he became chief strategy officer. That October, he also became chairman of Airbnb China, which goes by Aibiying locally. He still sits on the board. Earlier, in 2015, he oversaw Airbnb’s expansion into Cuba.

Airbnb is now a global platform. Bloomberg reports more than 5 million hosts and over 2 billion guests since 2008. The company reported about $12.2 billion in revenue for its latest full year, up 10%. Guests booked 533 million nights and seats, up 8%, according to its annual report filed with the SEC.

Growth now leans on new markets. Airbnb reported that nights booked by guests in India rose 50% in the last quarter of its latest full year. Brazil rose more than 20%. A chief strategy officer watches shifts like these closely.

Giving, family, and public life

On June 1, 2016, Blecharczyk, Chesky, and Gebbia signed the Giving Pledge. Warren Buffett and Bill Gates started that campaign. Signers promise to give away most of their wealth. Blecharczyk is married to Elizabeth Morey Blecharczyk, a neonatologist who treats newborns. They have two children and live in San Francisco.

Who Is Greg Hayes?

Education and early career

Hayes earned an economics degree from Purdue University and became a certified public accountant. That path made him a finance leader first and an operator second. Before United Technologies, he worked in finance at Sundstrand, an aerospace and industrial manufacturer.

RTX’s 2024 proxy statement listed his age as 63. It also credited him with 34 years of experience with the company and its predecessor.

Rise at United Technologies

Hayes joined United Technologies in 1999, when it merged with Sundstrand. He served as chief financial officer from 2008 to 2014. In November 2014, he became CEO, replacing Louis Chênevert. He added the chairman title in 2016.

As CEO, he turned a broad industrial group into a focused aerospace business. In 2015, he sold Sikorsky Aircraft, the helicopter maker, to Lockheed Martin. In 2018, he bought Rockwell Collins, which makes aircraft electronics. In 2020, he split off Otis, the elevator company, and Carrier, the heating and cooling business.

Creating RTX

The biggest move came in April 2020. United Technologies merged its aerospace units, Pratt & Whitney and Collins Aerospace, with Raytheon Company. Raytheon brought missiles and defense systems. The combined firm covered engines, aircraft systems, and defense.

The new company was first called Raytheon Technologies. It became RTX in 2023. Hayes served as CEO and became chairman in 2021.

RTX is huge. It reported adjusted sales of $88.6 billion for its latest full year. Its backlog of future orders stood at $268 billion at year end. By mid 2026, that backlog hit a record $289 billion. The company now expects about $95 billion to $96 billion in sales this year. Hayes shaped the company behind those numbers.

The powder metal setback

Hayes faced one hard test near the end of his term. In 2023, RTX found a quality problem with powder metal used in some Pratt & Whitney geared turbofan engine parts. Airlines had to inspect and pull engines early. In the third quarter of 2023, RTX took a charge of about $2.9 billion against operating profit. It also cut reported sales by about $5.4 billion. The board lowered Hayes’s bonus because of the matter. In December 2023, he announced that Calio would take over as CEO.

Stepping aside and life after RTX

Christopher Calio took over as CEO on May 2, 2024. Hayes became executive chairman. RTX announced in February 2025 that Hayes would leave the board. He stepped down on April 30, 2025. He then advised Calio until January 2, 2026. That role has ended.

Hayes has since taken on new work. He joined the board of BD, a medical technology company, in 2025. He has served on the board of Phillips 66, an energy company, since 2022. He also chairs the National Academy Foundation, a nonprofit that works on education.

Career Timeline: Nathan Blecharczyk and Greg Hayes

This timeline shows how two careers ran side by side. It does not suggest a shared project.

How Their Leadership Paths Compare

The careers of Nathan Blecharczyk and Greg Hayes look alike from far away. Both reached the top tier of a major company. Up close, the roads were very different.

Founder and career executive

Blecharczyk built something from nothing. He wrote code, learned the business, and later moved into strategy. Hayes joined a company that already existed. He earned trust on the finance side, then took the top job. One man started the engine. The other learned how to rebuild it while it ran.

Engineer and accountant

An engineer asks how a thing works. An accountant asks what it costs and what it returns. You can see that split in their choices. Blecharczyk’s work centers on product, platform, and long range plans.

Hayes made his biggest calls through deals. He sold Sikorsky, bought Rockwell Collins, spun off Otis and Carrier, and formed RTX. That pattern reads as a dealmaker’s career. It is an observation, not a claim from either company.

Growth platform and industrial group

Airbnb grows when more hosts list homes and more guests book trips. RTX sells engines, avionics, and defense systems under contracts that can last for years. Airbnb has to win customers every season. RTX leans on long relationships with airlines and governments. Those models need different leaders. Neither style is better. Each fits its company.

Net Worth and Pay

Bloomberg’s Billionaires Index puts Blecharczyk near $9.18 billion at its latest update. It counts about 62 million Airbnb shares, based on late filings. Some websites show far lower numbers, even under $1 billion. They appear to count only shares he holds directly, not shares in family trusts. Insider filings also show regular share sales in 2026. Selling shares does not erase wealth. It moves it from stock to cash.

MarketScreener estimated Hayes’s disclosed holdings at about $107 million in June 2026. Most of that is RTX stock. His pay is easier to check. RTX’s 2024 proxy statement shows the board approved an annual incentive of $2.78 million for 2023. It trimmed that award because of a manufacturing problem at Pratt & Whitney. His full package also included salary and stock awards. The proxy lists every number.
