- Max Levchin is a software engineer and entrepreneur born in Ukraine in 1975. He moved to the U.S. in 1991.
- Max Levchin is most famous for co-founding PayPal.
- Levchin has also successfully invested in Yelp, Affirm, and Evernote.
- He also co-created the Gausebeck-Levchin test, which became one of the earliest implementations of the challenge-response human verification test called CAPTCHA.
Max Levchin probably isn’t a name you know. But, if you’re like most Americans, you’ve probably sent or received funds via PayPal, which he co-founded in 1998. After all, in 2023, PayPal users are set to hit 223.3 million globally.
It’s also highly likely that you’ve been “challenged” by CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart), which was developed at PayPal by Levchin and his team. If the word “CAPTCHA” doesn’t ring a bell, think back to the last time you went to a website and saw a checkbox next to the text “I’m not a robot.” Levchin developed this security tool to differentiate between real users (humans) and automated users such as bots. (Although it does sometimes feel as if the CAPTCHA challenge presents itself simply to annoy us!)

Let’s find out more about Max Levchin’s life and innovations.
Who Is Max Levchin?
Max Levchin is primarily a software engineer and entrepreneur. He also dabbles in investing and even has an executive producer credit in a movie.
Levchin is known for co-founding the startup that eventually turned into PayPal. His contributions helped bulletproof the security and encryption features of the software. He was also one of the top dogs in what became known as the PayPal Mafia.
After leaving PayPal, Levchin, alongside other members of the PayPal Mafia, was involved in a string of successful investments in tech companies, including Yelp, Affirm, and Evernote. He also co-created the Gausebeck-Levchin test, which became one of the earliest implementations of the challenge-response human verification test, CAPTCHA.
Levchin’s parents lived in Kiev, Ukraine, when he was born. In 1991, at age 16, little Max moved to the U.S. with his parents and made a new home in Chicago. When they immigrated to the U.S., his family only had a few hundred dollars to their name.
As a young adult, Levchin studied computer science at the University of Illinois at Urbana-Champaign, eventually earning his bachelor’s degree. While completing his studies, Levchin founded four different tech companies, mainly focusing on selling online ad banners and white-label classified ads to various marketing networks and newspaper sites.
Although his first three attempts fell flat, the fourth matured and was acquired by a 90s online advertising cooperative named LinkExchange. The sale of this startup allowed Levchin to move his home from Illinois to California after graduating in 1997.
When he arrived in Palo Alto in 1998, Levchin didn’t have a place to stay at first. He made temporary arrangements to sleep on the floor of a friend’s home near the campus of the University of Stanford. During the day, Levchin would sneak into random Stanford lecture halls to take advantage of the air conditioning. As he wandered around Stanford one day, another friend of his, Luke Nosek, recommended he check out a lecture by a young entrepreneur named Peter Thiel.
It turned out the lecture was actually more of a seminar, with only six people in attendance. Levchin found Thiel’s ideas fascinating, so he hung around after the talk to chat up the lecturer. The pair hit it off immediately, and after their very first conversation, they decided to partner up and launch a startup together.
In 1998, the same year they met, Levchin and Thiel started a digital security company they called Fieldlink. Its main focus was helping its users safely store data in encrypted digital wallets on handheld devices of the time, which were called PDAs. They named Thiel the CEO and Levchin the CTO.
The team soon narrowed its focus to digital money transfers, developing a payment product called PayPal that immediately went viral. PayPal allows users to use their PDAs to instantly transfer money online to anyone else with a PDA and a PayPal account. A new focus deserved a new name, so Levchin and Thiel renamed the company Confinity.
In 2000, they merged Confinity with X.com, an online financial services company run by another friend from Stanford, Elon Musk. X.com provided a service similar to PayPal, so instead of competing, they decided to team up. They named the newly merged company PayPal, after their most popular product, and linked the new PayPal accounts to users’ email addresses instead of their PDAs.
The Gausebeck-Levchin Test
As Chief Technology Officer of PayPal, Levchin’s main responsibility was keeping the PayPal service safe and free of fraud. He did this by co-developing his very own CAPTCHA.
A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is an online testing system that determines whether a given user is a human or a bot. The Gausebeck–Levchin test, developed at PayPal by Max Levchin and his team, was one of CAPTCHA’s first widespread commercial applications.
Once PayPal switched to email addresses instead of PDAs, the company needed a way to ensure new accounts were being opened by real humans instead of bots. Levchin and his team implemented a kind of CAPTCHA that would pop up during important transactions to help prevent automated attempts at fraud. The Gausebeck–Levchin test displayed distorted text on the screen that was difficult for programs but easy for humans to recognize.
PayPal Goes Public
In 2002, after months of playing politics with the SEC and fiddling with lawyers, patents, and boards of directors, PayPal went public. Almost immediately, eBay, one of its chief competitors, acquired the company for $1.5 billion.
Levchin had a stake of 2.3% in the company. On the day of the acquisition, his shares were valued at around $34 million.
The price of the acquisition, however, was measured in more than just money. eBay’s corporate culture instantly began to take over PayPal’s more casual atmosphere. Within only four years, Levchin, Peter Thiel, Elon Musk, and many of the other 50 original employees had moved on.
Levchin stayed connected with his fellow members of the PayPal Mafia. In the following years, he would continue to work closely with Peter Thiel, Elon Musk, and a few others, co-founding and investing together in each other’s new tech startups and projects.
What Is Max Levchin Known For?
Post-PayPal Innovating and Investing
In 2004, a couple of years after the PayPal sale, Levchin used some of his earnings to open an online media-sharing service called Slide. He invested $7 million of his personal money to get the company running. Six years later, Slide was acquired by Google for $182 million.
A few months after Levchin opened Slide, two members of the PayPal Mafia, Russell Simmons and Jeremy Stoppelman invited him out for lunch. They were on the cusp of launching an online social network where customers could rate and review the businesses and services they used. They hoped it would one day take the place of the yellow pages, so they called it Yelp.
Levchin loved their idea and, before lunch was over, presented them with a check for a million dollars. That investment made him Yelp’s largest shareholder. He served as Yelp’s chairman of the board for over ten years.
In the 2000s and 2010s, Levchin invested in or joined in some capacity various tech startups and multinational conglomerates, including Google, Yahoo, Evernote, and Glow, a fertility app inspired by his experiences raising his children with his wife. He once said on Twitter that one of the most important heuristics he used to decide whether or not he should invest in a startup was whether he felt he would be interested in joining the company if the founders asked him to.
Although he has repeatedly stated his desire to stay away from politics, in 2015, Levchin was appointed to serve a three-year term on the Consumer Advisory Board of the U.S. Consumer Financial Protection Bureau. He became Silicon Valley’s first executive to serve on this board.
Also, in 2015, Levchin publicly announced he would be withdrawing from most of his involvement in the politics of business. This included renouncing his positions on the boards of Yelp, Yahoo, etc., in order to focus on Affirm, a new startup he had launched. Affirm is a tech financing company that loans people money to help them pay in installments for things they need right away. Customers can also open savings accounts and buy and sell bitcoin and other cryptocurrencies.
As CEO and co-founder of Affirm, Levchin’s stake amounted to almost 11% of the company. It went public in January 2021 and was valued at around $24 billion.
Max Levchin: Marriage, Divorce, Children and Personal Life
Max became a billionaire in January 2021, when Affirm went public, thanks mainly to his more than 27 million shares in the company. At the end of 2021, estimates of his net worth put it in the neighborhood of $3.4 billion.
In 2008, at age 33, Levchin finally convinced his girlfriend of many years, Nellie Minkova, to become his wife. She had briefly broken up with him back in 2002 when PayPal was sold to eBay. Levchin insists that her plan had always been to take him back, but he says the month he spent on his own felt like an eternity.
Max and his wife, Nellie Levchin, have two children. Their names, birthdays, and personal info remain private, although Levchin will tell you he loves cooking dinner for his whole family.
