This Ivy League reject taught himself to code at 7, built a $30m app by 18 and is treating college like a $100k vacation: ‘not gaining much from the classes’

Zach Yadegari, 18, isn’t new to being a tech entrepreneur. Instead of making money from lemonade stands growing up—he made it from apps.

In his teens, he started building apps he deemed as “small projects.” One of them isn’t so small anymore, as Cal AI has taken off to become a $30 million empire. The app allows users to track calories by taking a picture of their food, inspired by Yadegari’s own fitness journey. (Fortune reviewed financial records showing the app brings in several million dollars of revenue per month.)

Yadegari told Fortune about the wild ride of the last two years, from bringing in a mix of friends (all older than him) as co-founders, to being widely rejected by Ivy League schools despite a 4.0 GPA, a 34 ACT and entrepreneurial success, to why he’s decided to go to college anyway.

“I look at it as I’m paying $100,000 a year for a vacation,” he said.

Bulking up and scaling up

Yadegari said his success started with a personal project to bulk up when he was a (younger) teenager.

“I was very, very skinny my entire life growing up, and I wanted to start getting bigger and gaining weight,” Yadegari tells Fortune. When he realized a majority of his progress was coming from diet, he started to track his calories more and eat in surplus.

But there was something missing from his fitness journey. The app. It was “an awful experience” using the most popular app at the time. He found that he couldn’t eat at the cafeteria with his friends because he was eating pre-portioned meals that were weighed on scales, and he often had to skip eating at restaurants because he wouldn’t know the calories.

“For a kid, I was in school, that just wasn’t sustainable,” he added.

The experience was so bad for him, he said, that he gave up on most of his fitness journey for a while. But having some coding skills and considering the rise of AI tools like ChatGPT and Claude, he decided to just make one himself.

With the idea in mind, he brought the vision to partners he knew he could trust, one friend from coding camp and two people he met on X.com, as reported by CNBC. Together, Henry Langmack, Blake Anderson and Jake Castillo launched Cal AI in May 2024.

“We started making TikToks, we started partnering with influencers, and then we had pretty explosive growth,” he said.

Last year in July, encouraged by the positive feedback, he decided to flock to San Francisco with his co-founders to focus and hire about 15 employees. As written on his X account, investors tried to constantly “throw money at us [Cal AI],” which they rejected. A year and four months later—Cal AI brings in $30 million annually and the team is more than 30 people.

According to Yadegari, the app has a 90% accuracy rate. It’s free to download on both the Apple App Store and Google Play, with subscriptions priced at $2.49 per month or $29.99 annually. Yadegari was previously profiled by other outlets such as CNBC, CBS and TechCrunch.

Coding isn’t new to Yadegari

Starting as a coding whiz at just seven years old, and giving lessons for $30 an hour at age 10, he developed coding skills before the AI boom. By 12, he had put his first app, “Speed Soccer,” on the App Store.

In high school, he kept building. Yadegari started making money online after creating a gaming website called “Totally Science”, which allowed his peers at school to play unblocked games in school–that brought him in six figures.

“Everything I built up to that point was free,” Yadegari said.

“Over two years, [Totally Science] grew to 5 million users and started making $60,000 a month from banner ads I placed on the site. I sold it when I was 16 for $100,000—and that’s when I started building apps.”

School days

Being a self-starter at such a young age, Yadegari knew that the conventional path wasn’t meant for him after high school. He didn’t need to go to college to make millions, but that didn’t mean he wasn’t qualified.

He is currently undeclared in his major. He dropped out of the business school, and now takes classes in philosophy. He still takes one entrepreneurship class, but says he’s “not gaining much from the class material.”

“I never wanted to go to college. I’ve always been against the idea that everyone should follow the same formula: get good grades, go to a good college, get a degree, get a job, and then start making money. I hated that notion—and I used to fight with my parents about it all the time.”

Now, he combines parties with paychecks. In Miami, he lives in a house with a bunch of his like-minded app-building friends between the ages of 18-26. According to Yadegari, they are successful entrepreneurs like himself.

The young founders are building “App Mafia,” a community and brand where they educate people online by making content on how to build apps.

“We’re going to have a lot of ideas for shaping the future. We’re basically trying to lead the forefront of Gen Z builders,” he added.

Nvidia’s CEO says AI adoption will be gradual, but we still may all end up making robot clothing

Nvidia CEO Jensen Huang doesn’t foresee a sudden spike of AI-related layoffs, but that doesn’t mean the technology won’t drastically change the job market—or even create new roles like robot tailors.

The jobs that will be the most resistant to AI’s creeping effect will be those that consist of more than just routine tasks, Huang said during an interview with podcast host Joe Rogan this week.

“If your job is just to chop vegetables, Cuisinart’s gonna replace you,” Huang said.

On the other hand, some jobs, such as radiologists, may be safe because their role isn’t just about taking scans, but rather interpreting those images to diagnose people.

“The image studying is simply a task in service of diagnosing the disease,” he said.

Huang allowed that some jobs will indeed go away, although he stopped short of using the drastic language from others like Geoffrey Hinton a.k.a. “the Godfather of AI” and Anthropic CEO Dario Amodei, both of whom have previously predicted massive unemployment thanks to the improvement of AI tools.

Yet, the potential, AI-dominated job market Huang imagines may also add some new jobs, he theorized. This includes the possibility that there will be a newfound demand for technicians to help build and maintain future AI assistants, Huang said, but also other industries that are harder to imagine.

“You’re gonna have robot apparel, so a whole industry of—isn’t that right? Because I want my robot to look different than your robot,” Huang said. “So you’re gonna have a whole apparel industry for robots.”

The idea of AI-powered robots dominating jobs once held by humans may sound like science fiction, and yet some of the world’s most important tech companies are already trying to make it a reality.

Tesla CEO Elon Musk has made the company’s Optimus robot a central tenet of its future business strategy. Just last month, Musk predicted money will no longer exist in the future and work will be optional within the next 10 to 20 years thanks to a fully fledged robotic workforce.

AI is also advancing so rapidly that it already has the potential to replace millions of jobs. AI can adequately complete work equating to about 12% of U.S. jobs, according to a Massachusetts Institute of Technology (MIT) report from last month. This represents about 151 million workers representing more than $1 trillion in pay, which is on the hook thanks to potential AI disruption, according to the study.

Even Huang’s potentially new job of AI robot clothesmaker may not last. When asked by Rogan whether robots could eventually make apparel for other robots, Huang replied: “Eventually. And then there’ll be something else.”

The ‘Mister Rogers’ of Corporate America shows Gen Z how to handle toxic bosses

After two decades of climbing the corporate ladder at companies ranging from ABC, ESPN, and Charter Communications (commonly known as Spectrum), Timm Chiusano quit it all to become a content creator.

He wasn’t just walking away from high titles, but a high salary, too. In his peak years, Chiusano made $600,000 to $800,000 annually. But in June of 2024, after giving a 12-week notice, he “responsibility fired himself” from his corporate job as VP of production and creative services at Charter.

He did it all to help others navigate the challenges of a workplace, and appreciate the most mundane parts of life on TikTok.

@timmchiusano

most people are posting their 2024 recaps; these are a few of my favorite moments from the year that was, but i need to start reintroducing myself too i dont have a college degree, no one in my life knew that until i was 35 when i eventually got my foot in the door in my early 20’s after a few years of substitute teaching and part time jobs, i thought for sure i had found the career path of my dreams in live sports production i didn’t think i had a chance of surviving that first college football season but i busted my ass, stuck around and got promoted 5 times in 5 years then i met a girl in Las Vegas, got married in 7 months, and freaked out about my career that had me travelling 36 weeks a year i had to find a more stable “desk job”, i was scared shitless that i was pigeonholed and the travel would eventually destroy my marriage i crafted a narative for espn arguing they needed me on their marketing team because of my unique perspective coming from the production side i got rejected, but kept trying and a year i got that job the 7 years with espn were incredible, but also exhausting and raised all kinds of questions about corporate america, toxic situations, and capitalism in general why was i borderline heart attack stressed so often when i could see that my ideas were literally generating 2,000 times the money that i was getting paid? in 2012 i had a kid and in 2013 i got the biggest job of my career to reinvent how to produce 20,000 commercials a year for small business it took 12 rounds of interviews, a drug test i somehow passed, and a background check that finally made me tell my wife of 8 years that i didnt have a college degree they brought me in the thursday before my first day and told me what i told grace in that clip the next decade was an insane blur; i saw everything one would ever see in their career from the perspective of an executive at a fortune 100 i started making tiktoks, kinda blacked out at some point in 2019 and responsibly fired myself in 2024 to see what i might be capable of on my own with all the skills i picked up along my career journey now the mission is pay what i know forward, and see if i can become the mr rogers of corporate america cc: @grace beverley @Ryan Holiday @Subway Oracle

What started as short-video vlogs on just about anything in 2020 (reviews on protein bars, sushi, and sneakers) later transitioned to videos on growing up, and dealing with life’s challenges, like coming to terms when you have a toxic boss. Today, his platform on TikTok has over 1 million followers.

With the help of going viral from his “loop” format where videos end and seamlessly circle back to the beginning, he began making more videos as a side-hustle on top of his day-to-day tasks in the office.

“How can I get people to be smarter and more comfortable about their careers in ways that are gonna help on a day-to-day basis?” Chiusano told Fortune.

Today, he could go by many titles: former vice president at a Fortune 100 company, motivational speaker, dad, content creator, or as he labels himself, the Mister Rogers of Corporate America.

Just as the late public television icon helped kids navigate the complexities of childhood, Chiusano wants to help young adults think about how to approach their careers and their potential to make an impact.

“Mister Rogers is the greatest of all time in his space. I will never get to that level of impact. But it’s an easy way to describe what I’m trying to do, and it consistently gives me a goal to strive for,” he said. “There are some parallels here with the quirkiness.”

Firing himself after 25 years in the corporate world

Even with years in corporate, Chiusano doesn’t resemble the look of a typical buttoned-up executive. Today, he has more of a relaxed Brooklyn dad attire, with a sleeve of tattoos and a confidence to blend in with any trendy middle aged man in Soho. During our interview, he showed off one of the first tattoos he got: two businessmen shaking hands, a reference to Radiohead’s OK Computer album.

“This is a dope ass Monday in your 40s,” began one of his videos.

It consisted of Chiusano doing everyday things such as eating leftovers, going to the gym, training for the NYC marathon, taking out the trash, dropping his daughter off at school, a rehearsal for a Ted Talk, eating lunch with his wife, and brand deal meetings. Though the content sounds pretty normal, that’s the point.

“The reason why I fired myself in the first place was to be here,” he says in the video while picking his daughter up from school.

Today, Chiusano spends his days making content on navigating workplace culture, public speaking, brand deals, brand partnerships, executive coaching, writing a book, and the most important job: being a dad to his 13-year-old daughter Evelyn.

“I’m basically flat [in salary] to where I was, and this is everything I could ever want in the world,” he said. “The ability to send my kid to the school she’s been going to, eat sushi takeout almost as much as I’d like, and do nice things for my wife.”

In fact, when sitting inside one of his favorite New York City spots, Lure Fishbar, he keeps getting stopped by regulars who know him by name. He points out that one of his favorite interviews he filmed here was with legendary filmmaker Ken Burns.

Advice to Gen Z

In a time where Gen Z has been steering to more unconventional paths, like content creation or skill trades rather than just a 9-to-5 office job, Chiusano opens up a lens to what life looks like when deciding to be present rather than always looking for what’s next—a mistake he said he made in his 20s.

Instead, he wants to teach the younger generation to build skills for as long as you can, but “if you are unhappy, that’s a very different conversation.”

“I think some people will make themselves more unhappy because they feel like that’s what’s expected of a situation,” he said.

“I would love to be able to empower your generation more, to be like somebody’s gonna have to be the head of HR at that super random company to put cool standards and practices in place for better work-life balance for the employees.”

Mark Zuckerberg says the ‘most important thing’ he built at Harvard was a prank website

Published

For Mark Zuckerberg, the most significant creation from his two years at Harvard University wasn’t the precursor to a global social network, but a prank website that nearly got him expelled.

The Meta CEO said in a 2017 commencement address at his alma mater that the controversial site, Facemash, was “the most important thing I built in my time here” for one simple reason: it led him to his wife, Priscilla Chan.

“Without Facemash I wouldn’t have met Priscilla, and she’s the most important person in my life,” Zuckerberg said during the speech.

In 2003, Zuckerberg, then a sophomore, created Facemash by hacking into Harvard’s online student directories and using the photos to create a site where users could rank students’ attractiveness. The site went viral, but it was quickly shut down by the university. Zuckerberg was called before Harvard’s Administrative Board, facing accusations of breaching security, violating copyrights, and infringing on individual privacy.

“Everyone thought I was going to get kicked out,” Zuckerberg recalled in his speech. “My parents came to help me pack. My friends threw me a going-away party.”

It was at this party, thrown by friends who believed his expulsion was imminent, where he met Chan, another Harvard undergraduate. “We met in line for the bathroom in the Pfoho Belltower, and in what must be one of the all time romantic lines, I said: ‘I’m going to get kicked out in three days, so we need to go on a date quickly,’” Zuckerberg said.

Chan, who described her now-husband to The New Yorker as “this nerdy guy who was just a little bit out there,” went on the date with him. Zuckerberg did not get expelled from Harvard after all, but he did famously drop out the following year to focus on building Facebook.

While the 2010 film The Social Network portrayed Facemash as a critical stepping stone to the creation of Facebook, Zuckerberg himself has downplayed its technical or conceptual importance.

“And, you know, that movie made it seem like Facemash was so important to creating Facebook. It wasn’t,” he said during his commencement speech. But he did confirm that the series of events it set in motion—the administrative hearing, the “going-away” party, the line for the bathroom—ultimately connected him with the mother of his three children.

Chan, for her part, went on to graduate from Harvard in 2007, taught science, and then attended medical school at the University of California, San Francisco, becoming a pediatrician.

She and Zuckerberg got married in 2012, and in 2015, they co-founded the Chan Zuckerberg Initiative, a philanthropic organization focused on leveraging technology to address major world challenges in health, education, and science. Chan serves as co-CEO of the initiative, which has pledged to give away 99% of the couple’s shares in Meta Platforms to fund its work.
