The tech industry with all its innovation, glamour, and youth can still be incredibly stressful. As companies launch, go public, and tackle turmoil, executives go gray, lose weight, and forget to buy eye cream.
Tech execs like Facebook'sMark Zuckerberg and Amazon'sJeff Bezos were once fresh faces on the scene. Now, they've crafted themselves into multibillionaires while growing their businesses into worldwide success stories.
Take a look at how dramatically these tech execs have changed since they've started the job.
Any time Mark Zuckerberg mentions Facebook, he often brings up how he started it in his dorm room at Harvard when he was just 20 years old. Early photos of Zuckerberg show him in a plain t-shirt, sweats, and Adidas sandals lounging on the steps of his would-be alma mater.
And although Zuckerberg's wardrobe hasn't changed much (albeit the slides and sweats), the company he founded has.
Today, Facebook has more than 2.3 billion users and has fought to keep its reputability as privacy scandals continue to plague the social network and Zuckerberg himself.
Take a look at how dramatically other world-famous CEOs changed over the course of their job:
Jeff Bezos founded Amazon when he was 30 in 1994. Like other famed tech execs, he started the company in his garage in Seattle.
Fast forward to 2019, and Bezos, 55, is the wealthiest person in modern history, with a net worth of $150 billion. In September, Amazon briefly became the second US company to achieve a valuation of more than $1 trillion.
Mark Zuckerberg founded "The Facebook" when he was 20 years old in 2004 while studying at Harvard University.
Zuckerberg, now 34, has a net worth of over $64.1 billion. Today, Facebook has more monthly active users than any single country in the world has people — 2.3 billion.
Steve Jobs and Steve Wozniak started Apple Computer Company in 1976 in Jobs' garage. Jobs was just 21.
Jobs ushered in a new era at Apple, introducing the iPhone and iPad. In 2003, he was diagnosed with a unique form of pancreatic cancer.
Steve Jobs named Tim Cook, then 51, the COO of Apple in 2007, the same year the iPhone was released. Jobs noticed Cook's leadership quickly, and handed off the CEO title to Cook in 2011.
Today, Apple is worth $1 trillion under Cook, 58. It was worth about $330 billion at the time that Jobs passed.
Bill Gates and Paul Allen founded Microsoft in 1975. Gates was just 20 years old, and like Zuckerberg, he dropped out of Harvard to spend more time with his technology startup.
Today, Gates, 63, has a net worth of $97 billion.
Indra Nooyi became CEO of Pepsi in 2006.
After 24 years with the company, Nooyi announced last August she would be stepping down. In the year preceding her retirement, she earned $31 million.
Jack Dorsey founded Twitter with Ev Williams in 2006 when he was 30.
Dorsey, now 42, was renamed the CEO of Twitter in 2015. Today, the company has over 321 million monthly users and took in $909 million last year. Dorsey himself has a net worth of $5.5 billion.
Evan Spiegel founded Snapchat with Reggie Brown and Bobby Murphy in 2011 when he was 21 years old.
Today, Spiegel is 28 and one of the youngest billionaires in the world. His net worth hangs just short of $3 billion.
In 2004, Elon Musk, then 33, made the first of what would be $70 million of total investments in Tesla, an electric car company cofounded by veteran startup exec Martin Eberhard.
Musk, now 47, was named the CEO of Tesla in 2008 after investing in the company with his own money. Tesla went public in 2010, and raised $226 million in the IPO, becoming the first car company to go public since Ford in 1956. Today Musk has a net worth of $23.8 billion.
Larry Page and Sergey Brin founded Google in 1998 when they were both 25 years old.
Page, now 45, has a net worth of $54.1 billion, and is CEO of Alphabet, Google's parent company. Page is also the ninth-richest person in the world.
Brin is just behind Page in terms of net worth, at $52.7 billion.
Larry Ellison co-founded Oracle, the software firm, in 1977 when he was 33 years old. He said he started the company because he saw a gap in management databases.
Ellison, now 74, gave up the CEO role at Oracle in 2014. Forbes pegs his net worth at about $56 billion.
Satya Nadella joined Microsoft in 1992 at age 25, when founder Bill Gates was still the reigning CEO.
Nadella is only the company's third CEO, following Steve Ballmer and Bill Gates.
Hailed as one of the world's most powerful women, Meg Whitman first worked for companies P&G and Hasbro before she became CEO of eBay in 1998.
After joining Hewlett Packard's board in 2011, Whitman was offered the CEO position.
Michael S. Dell officially founded his company under the name PC's Limited in 1984.
After several years in a chairman position, Dell returned to his CEO role in 2007 and has continued to head the company ever since.
