In June, Forbes ranked him ninth on its 2026 Top Creators list with $30 million in earnings, and his Netflix competition series Schooled! is in the works.

Mark Rober Early Life

Mark was born in Orange County, California, and grew up in Brea as the youngest of three children, with an older brother, Brian, and an older sister, Lisa. He was a spacey kid who didn’t speak until he was three or four, and people around him assumed he just wasn’t very bright. His sister Lisa has said the family joked that he was always off in la-la land. That changed in third grade, when he took his first standardized test and scored off the charts, and his mother told the teacher there must be a mistake because it couldn’t be her son.

His mother, Caroline, was the biggest influence on his life. She was a stay-at-home mom who barely graduated high school, but she made creativity a habit at home. When he was about six, he was asked to help make dinner and chop onions, and to stop his eyes from watering, he went upstairs, found swim goggles, and wore them while cutting. She laughed, called it a great idea, and took a photograph, which in those days meant something, and he says that moment taught him he was encouraged to come up with his own solutions. She did the same when he nailed two blocks of wood together and called it a violin.

He was also a prankster. Four times while he was growing up, his father sat him down and told him he needed to get serious and couldn’t prank his way through life, a line he now laughs about. Meanwhile, he played soccer, did well socially, and fell for math and physics. As a child, he loved designing McDonald’s PlayPlaces in his head, imagining where he’d put a foam pit or a tunnel, and he later noticed a link between that habit and what he has built at CrunchLabs. His father often took the kids to the Wright-Patterson Air Force Museum, a tradition Mark later continued with his own son.

He graduated from Brea Olinda High School in 1998 and went to Brigham Young University to study mechanical engineering.

Mark Rober Family

Mark’s father is Larry Lee Rober, a University of Washington graduate. His mother, Caroline Melissa Braxton Rober, was a genealogist and lecturer who died of a rare and aggressive form of ALS in February 2011, months before Mark posted his first YouTube video in October 2011. In her final years, Mark and his brother Brian built her a special jacuzzi lift so she could keep enjoying the tub. He has said in podcasts that she’s the reason he believes in encouraging kids to experiment, and he talks about her often when he describes CrunchLabs.

His older sister, Lisa Rober Henderson, graduated from BYU in 2001, and his older brother, Brian, works in building and has appeared in some of his videos.

Mark has one son, who is 19 and on the autism spectrum. For years he kept his son out of his videos, and in 2021 he published “The Truth About My Son,” explaining that he’s protective because the internet can be harsh on people who are different. He has said the nightly routine of telling the same jokes to his son and his stuffed animals is the best part of his day, and that his son has changed how he thinks about success.

Mark Rober Relationship

Mark married Lisa Rober, born Lisa Nicole Earl, in 2015, and the couple settled in Sunnyvale, California, where they raised their son. After CrunchLabs launched in 2022, Lisa worked on the team, helping with marketing and content strategy.

He filed for divorce on July 6, 2021, at the Santa Clara County Superior Court in California. In a September 2024 post on X, he confirmed that it had been about three and a half years since the divorce, and that he hadn’t worn a wedding ring in his videos for that long. He keeps his personal life private to protect himself and the people close to him, and he and Lisa share the job of raising their son.

Mark Rober Education

He earned his bachelor’s degree in mechanical engineering from Brigham Young University in 2004, then a master’s degree in the same field from the University of Southern California in 2014, which he completed while working at NASA. He later gave a TEDx talk in 2015 called “How to Come Up with Good Ideas” and another on the Super Mario Effect, which argues that people learn better when they treat failure like a video game. In 2023, he delivered the commencement address at MIT.

Mark Rober Career

Nine Years at NASA

Straight out of BYU in 2004, Mark joined NASA’s Jet Propulsion Laboratory in California, where he stayed for nine years and spent seven of them on the Curiosity rover, which is now on Mars. He designed and delivered hardware for several JPL missions, including GRAIL, SMAP, and the Mars Science Laboratory. He was also one of the main architects of JPL Wired, a company-wide knowledge wiki, and published a case study on applying wiki technology in a high-tech organization. His NASA salary was between $120,000 and $150,000 a year.

The First Viral Video and Digital Dudz

While still at NASA, he began making viral videos. In October 2011, a few months after his mother died, he recorded his first YouTube video, a Halloween costume that used two iPads to create the illusion of a hole through his torso, and it collected 1.5 million views in a single day. The next year, he launched Digital Dudz, an online costume company based on the same idea, and earned $250,000 in its first three weeks. By 2013, his app-integrated costumes were in stores like Party City, and later that year he sold the company to the UK costume firm Morphsuits, which gave him the freedom to leave NASA.

Apple and the YouTube Breakthrough

From 2015 to early 2020, he worked at Apple in the Special Projects Group, where he wrote two patents involving virtual reality in self-driving cars. His work stayed secret until Variety reported on it in 2018. Meanwhile, he kept posting videos on the side, with topics ranging from April Fools’ pranks to escape rooms to filming primates in zoos.

His real breakthrough came in December 2018 with the glitter bomb video, in which he built a decoy package that sprayed glitter and a foul smell on porch pirates while filming them. It collected 25 million views in a day. After it went viral, he admitted that two of the five thieves shown were actually friends of a person he hired to help, and he removed those clips and apologized.

He turned the glitter bomb into a franchise. In December 2019, he teamed up with Macaulay Culkin on a second version, and in 2020, he built a third with help from YouTube scam-baiters Jim Browning and Scammer Payback. Using the bait packages to track money mules, the group helped authorities arrest officials connected to scam call centers in India, which led to the shutdown of those centers and the arrest of 15 senior officials.

In 2020, he released Backyard Squirrel Maze, in which he built an obstacle course to keep squirrels from stealing from his bird feeders. By September 2023, the original had 114 million views, and the sequels had 80 million and 25 million. His channel took six years to reach 300,000 subscribers, and he sometimes spends 200 hours of footage to produce a ten-minute video. Today, a team of about 100 people helps produce his videos, and some episodes cost seven figures to make. His projects have included teaching physics through roller coasters, an Alcatraz escape experiment, a robotics video with soccer star Cristiano Ronaldo, and a $5 million satellite that let anyone take a selfie with Earth.

TV, Fundraisers, and CrunchLabs

In 2020, he starred with Jimmy Kimmel in the Discovery Channel’s hidden-camera series Revengineers and in This Is Mark Rober, and he has made many appearances on Jimmy Kimmel Live!, including guest-hosting in July 2022. In 2022, he founded CrunchLabs, a company that sells subscription Build Boxes with engineering projects for kids, with Jim E Lee as CEO. CrunchLabs signed an exclusive global deal with toy company Moose Toys, hired former Lionsgate and Discovery executive Scott Lewers as chief content officer in June 2025, launched in India in 2025, and partnered with Chess.com on a Mark Rober chess bot. In November 2025, its videos began streaming on Netflix, where they got more than 12 million views in two months, and a third season followed on March 16, 2026. He also appeared in Elmo & Mark Rober’s Merry Giftmas special and on Skyscraper Live.

Netflix and Class CrunchLabs (2025 to 2026)

In August 2025, Netflix announced Schooled!, a competition series for kids hosted by Mark and produced with Jimmy Kimmel’s Kimmelot. Netflix began casting contestants aged 9 to 17 in March 2026, promising booby-trapped lockers, secret passageways, a Jell-O pool classroom, and lots of elephant toothpaste.

His largest project in 2026 is Class CrunchLabs. He announced the free curriculum at a TED talk in April, partnered with YouTube and the National Science Teaching Association on June 29, and released the first courses for grades 6 to 8 on September 29, with more than 1,000 videos planned across 34 languages. He will volunteer one week of every month for the next four and a half years to make videos for it. The project also received a $7.2 million grant to create the CrunchLabs.org Foundation, plus the $2.5 million grant from YouTube and Google.org on October 6, which will fund translations and research and keep it free. GeoGuessr star Trevor Rainbolt is among the creator co-stars.

Mark Rober Charity Work and Philanthropy

Charity has become a big part of his career. In October 2019, he and MrBeast launched Team Trees, which aimed to raise $20 million to plant 20 million trees. In October 2021, they followed it with Team Seas, targeting $30 million for ocean cleanup. In 2025, they launched Team Water, which raised more than $40 million for WaterAid by September. In April 2021, Mark and Jimmy Kimmel hosted the Color the Spectrum livestream for NEXT for Autism, which raised $3 million, and Class CrunchLabs is the biggest of all, with Mark committing $55 million to $60 million of his own money.

Mark Rober Controversies

His career has had a few notable controversies. In 2018, he admitted that two of the thieves in his first glitter bomb video were staged, and he apologized. In April 2021, after the Color the Spectrum livestream raised $3 million, some autism advocates criticized the fundraiser and the group it supported.

The biggest backlash came in March 2025, when he posted “Can You Fool a Self-Driving Car?” on March 15. The video showed a Tesla Model Y hitting a painted fake wall while a lidar-equipped vehicle from Luminar stopped. Critics said the Tesla was on Autopilot, not the more advanced Full Self-Driving software the title implied, and pointed out that Luminar, a lidar company, was thanked in the description. He posted raw footage on March 17, and Luminar removed the video from its homepage, while the company’s stock jumped about 20% during the debate.

Mark Rober Net Worth

Mark Rober’s net worth in 2026 is $50 million, and he earns about $30 million a year, or roughly $2.5 million a month before taxes and expenses. Forbes ranked him ninth on its 2026 Top Creators list with those $30 million in earnings, up from $25 million on its 2025 list, and he has more than 90 million followers across platforms.

The foundation of his income is YouTube. His videos collect hundreds of millions of views every year, and a team of about 100 people produces episodes that can cost seven figures. Ad revenue from the channel is steady, but sponsorships add a lot more, since brands such as Rivian, Google, and Disney pay to be featured in his videos.

The biggest asset is CrunchLabs, the subscription STEM box company he founded in 2022, which brings in more than $50 million a year in retail revenue, with the Moose Toys licensing deal adding to it. Netflix is a newer source, since CrunchLabs videos stream there and he hosts and executive-produces Schooled!. Earlier in his career, he earned $120,000 to $150,000 a year at NASA, the 2013 sale of Digital Dudz gave him early capital, and Apple paid him a salary from 2015 to 2020. Speaking appearances, like his MIT commencement address, add smaller amounts.

A big part of his money goes back out. He has committed $55 to $60 million to the free Class CrunchLabs curriculum and gives large amounts through his fundraisers.
