• The world's top YouTuber, MrBeast, has found his first CMO.
• His company promoted its consumer goods president, marketing vet Michelle St. Jacques, to the role.
• She'll lead marketing for the MrBeast brand while retaining the consumer goods remit.

MrBeast has found his first CMO, Business Insider exclusively learned.

The top YouTuber's company promoted Michelle St. Jacques to the role. St. Jacques has served as president of consumer goods at Beast Industries — notably overseeing Feastables, MrBeast's snack and candy company — since February.

In her new role, she'll add marketing duties for the star's holding company, while continuing to oversee consumer goods. She's based in Chicago.

Beast Industries started the search earlier this year, a move that reflected the company's growing ambitions. It's been expanding far beyond its core YouTube channel — which has over 524 million subscribers — and seeks to become a Disney-style entertainment giant.

Beast Industries CEO Jeff Housenbold said in a memo to staff, viewed by Business Insider, that he considered external candidates for the CMO role but decided St. Jacques was the best person for the job.

"In her time at Beast, MSJ has shown she can set clear strategy and deliver strong execution for our products and partners," he wrote. "She has served as both CMO and Chief Commercial Officer and built iconic consumer brands like Dove, Heinz, Miller Lite, and Coors Light. She's also a world-class people leader who knows how to build high-performing teams."

St. Jacques joined the company following a slowdown in Feastables' growth.

Housenbold wrote that St. Jacques' remit would involve defining the MrBeast brand and making sure everything the company does ladders up to the same positioning; leading marketing for MrBeast and partner brands; and overseeing the viral marketing team. He said that he saw an opportunity to lean into e-commerce and performance marketing to drive customer acquisition and retention.

St. Jacques steps into a role overseeing a brand that's looking to lessen its reliance on its famous founder. Her job requires someone who can do everything from getting people to theatrical releases — Donaldson lent his voice to "Angry Birds Movie 3," which is scheduled for a December release — to selling snacks and toys in stores, or pitching fans on phone plans and financial products.

Beast Industries has made a string of big hires to bulk up its executive suite. Along with Feastables, the company has begun to move into financial services with the acquisition of the Step app and has planned a mobile phone service.

The company is also laying the groundwork to expand into ad and marketing services for brands and additional services for other independent content creators like MrBeast, and has teased a membership program.

• Steven Bartlett's "Diary of a CEO" has been fact-checking health and science episodes following a BBC probe.
• The show uses pop-ups to provide more context during the show, and research reports go deeper.
• There are weaknesses to its approach: the reports are long and dense, while the pop-ups are limited to video.

The top producer of the hit podcast "The Diary of a CEO" says the show has raised its bar for accuracy, an effort that began after a BBC investigation found it had shared harmful health misinformation.

"We're being more rigorous than we have in the past," Hans Sahni, the executive producer for "DOAC," told Business Insider. "That bar gets higher and higher every day."

The BBC reported in late 2024 that 15 of 23 health-related episodes contained an average of 14 potentially harmful claims.

A core part of "DOAC's" accuracy effort is fact-checking its guests. The show began its own fact-checking about six months after the BBC report. The team runs every episode through an AI-assisted review using Claude, Gemini, and Consensus. It also hired an independent medical Ph.D. researcher to review its health and wellness episodes.

Sahni said the show is putting every new episode through this process, and has fact-checked 71 episodes with the Ph.D. researcher. That amounts to about 13% of the 540 long-form interviews in its YouTube catalog. Sahni said the team is exploring the idea of fact-checking previously published episodes.

"DOAC's" fact-checking effort shows how independent creators are acting more like traditional media companies as they grow their audiences and attract the interest of big advertisers, who want their ads to run in brand-safe environments. Health and wellness have become particularly fraught topics, as many creators — including major stars like Joe Rogan — have been criticized for not pushing back against fringe views espoused by some of their guests.

"DOAC" host Steven Bartlett has come under more scrutiny as his megaphone has grown. "DOAC" has about 21 million subscribers on YouTube and regularly ranks as the top business podcast on Spotify. Bartlett recently told Fortune he projects the show will make $60 million this year from sponsorships and other sources.

In the video version of "DOAC" on platforms like YouTube and Spotify, when contested or complex topics arise, the show displays temporary pop-ups called "DOAC Community Notes" to rebut a guest or provide additional context. These are the result of the internal team's review or collaboration between the researcher and the show's team, who make the final call on what to put on screen.

The decision is based on the stakes of the claim, how strongly it's challenged by scientific literature, and what context is useful to the viewer in the moment — with an emphasis on fewer, higher-value interruptions.

The audio version doesn't have community notes, but information shared by the guest is cut if the team determines it to be inaccurate. An extensive fact-checking research document is linked in the show notes.

Sahni said the show's guest-booking and research teams have also become more disciplined in evaluating potential guests.

'DOAC's' approach has its limits

Angie Drobnic Holan, director of the International Fact-Checking Network, a Poynter project, applauded the show for making an effort to provide more accurate and contextual information.

"I would like to see more podcast hosts presenting information in context," she said. "The bigger the audience, the bigger the responsibility, especially when there's risk for harm."

Holan saw some limitations to "DOAC's" approach, though.

She said the sourcing on the Community Notes was unclear to viewers, as was who wrote the research briefings. She questioned whether the audience would read them, given that they're long and dense and don't present clear takeaways. The research documents often run upward of 80 pages. "DOAC" said it didn't have reliable user data on readership but was looking at getting that measurement.

Holan suggested that, overall, it's better to vet guests beforehand and have the interviewer fact-check the guest as they go.

Sahni said "DOAC" isn't a news program and doesn't present itself as such. At the same time, the show has a responsibility to the audience, he added.

Sahni said his team is working to improve the fact-checking process based on audience feedback and to expand its scope. For example, some viewers have said the pop-ups disappear too quickly or that there are too many of them.

The team uses Consensus, an AI research platform, in the fact-checking process and is exploring the use of its Consensus Meter, a visual feature, on-screen.

Figuring out how to present the same info on audio as on video without interrupting the listening experience is another hurdle. Right now, audio listeners can access the research document, but there's no audio equivalent of the on-screen pop-up.

Pop-ups challenged guests on drug and science claims

"DOAC" has had ample opportunity to put its fact-checking to work. Bartlett recently interviewed neuroscientist and podcaster Andrew Huberman, who's been called out for promoting unapproved treatments.

Throughout the interview, which has over 8 million views, occasional pop-ups challenge Huberman's medical claims, especially about peptides and weight-loss drugs.

Huberman said his sleep improved after he took the peptide pinealon. A 20-second pop-up appeared that read in part, "Evidence from human clinical studies remains limited."

Another pop-up read, in part: "Interest in peptides has surged, particularly for weight loss and skin health, but many marketed products are not FDA-approved and lack strong evidence from human clinical trials."

When Huberman calls the weight-loss drug Retatrutide "amazing" and says people lost about one-third of their body weight on it, a pop-up cautions that the drug remains under investigation and isn't FDA-approved.

In an episode with sleep specialist Michael Breus that has 13 million views, Breus said 75% of the reason for insomnia is anxiety and depression. The research doc said insomnia has multiple contributors.

When aging researcher David Sinclair recommended eating a Brazil nut a day for its selenium, a pop-up warned that excessive intake can cause toxicity.

"There's a tension between having a provocative guest and presenting the most accurate information we possibly can," Sahni said. "We're always going to lean toward being as accurate as we feel we can be. We're not journalists. None of us are and don't purport to be the news."

• MrBeast has an unusual expectation for ex-employees: Don't talk about MrBeast on social media — at all.
• Labor lawyers said the language in a letter outlining obligations for departing employees was uncommonly broad.
• A MrBeast rep said the language is meant to protect employees and the company from harassment.

MrBeast has an unusual expectation for departing employees: The world's top YouTuber doesn't want them to post about him — even if they're saying nice things.

Employees leaving the company of MrBeast, whose real name is Jimmy Donaldson, receive a letter outlining their obligations, including an "expectation" that they refrain from creating, commenting on, or engaging with social posts involving Donaldson, his company Beast Industries, or any of its employees. Business Insider viewed one such letter and confirmed it was the standard version used by the company.

The letter also states that the employee should not disclose nonpublic information about the company or make false or disparaging statements about it.

Three employment lawyers told Business Insider that the letter had a few uncommon features, pointing particularly to the references to social media.

"It does seem like an unusual burden to not be able to comment on social media," said V. James DeSimone, a California-based attorney. Plus, the letter doesn't offer any severance or other consideration in exchange, he added.

A Beast Industries spokesman said the social media language is intended to protect employees and the company from harassing behavior on social media.

Evan Fray-Witzer, of the firm Ciampa Fray-Witzer — who has experience working with creators — said the language in the MrBeast letter was broader than typical nondisparagement clauses he's seen. That's because it covers all comments, not just negative ones, and also extends to every post that references the company.

"If you were to read this literally, the person couldn't hit the 'like' button on a MrBeast post," Fray-Witzer said. "That's absurd."

Donaldson has been chasing YouTube fame since he was a teen, and the colossus he's built is the result of the tight creative control he exerts. He's known to obsess over his videos and his image and to kill projects he doesn't believe meet his standards.

Russell Berger of Offit Kurman said the language might be understandable in the context of a social media star's company, but thought the letter was unusually formal, long, and cold in tone.

"This is more of a putting-you-on-notice way of doing it," he said. "Mostly when people leave a job, they don't get a reminder of what they can and can't do."

Legal bark or bite?

Fray-Witzer said the company's motivation is understandable: It likely doesn't want former employees undermining its brand or profiting from MrBeast's content.

The 28-year-old creator, who has over 523 million YouTube subscribers, has been rapidly scaling up his company, which was valued at around $5 billion last year. The operation has grown to nearly 800 employees as it has expanded into areas like candy and financial services.

"Where it becomes more questionable and heavy-handed is the extent that it is being used simply to silence former employees from saying anything about MrBeast or the company," Fray-Witzer said of the letter.

The lawyers who spoke with Business Insider said the letter isn't a contract and is likely not enforceable.

DeSimone said, however, that if the employee previously signed an agreement saying they wouldn't comment about Beast Industries on social media, and then did so, the company could potentially have a basis for legal action.

It might be hard to get a judge to enforce the provision, however, and MrBeast would likely "have to prove some sort of damages," Fray-Witzer said.

Even if the language isn't enforceable, it could still have a chilling effect.

"The question for the employee is always, what's worth the juice here?" DeSimone said.

• Influencer marketers from Disney, the NFL, and more shared novel ways they're using platforms today.
• They're embracing Substack for cultural cachet, Threads to experiment, and YouTube for entertainment.
• Brands are also bringing creators in earlier, treating them more like creative partners.

Creators are jumping among an ever-wider mix of platforms and formats — and brands are scrambling to follow them.

We asked the most innovative marketers working with influencers which platforms and tactics have their attention right now — and why.

Marketers from Disney, e.l.f. Beauty, and others told us they're using platforms like TikTok to own the red carpet, Substack to align with tastemakers, and Threads to experiment.

"YouTube is a home for creators. TikTok is a great way to get discovery," said Ian Trombetta, the National Football League's senior vice president of global social, creator, and content marketing. "And then Instagram is another big one for us as it relates to discovery. Even platforms like X and Reddit have a really important role to play."

Beyond platforms, brands like Keurig Dr Pepper are also exploring ways to work directly with creators, involving them earlier in the campaign process.

"A major shift has been pivoting away from rented reach to true collaboration," said Samim Sadrzadeh, Disney's director of creator content and partnerships. "For a long time, the industry treated creators as ad placements. We think that significantly undersells the value they actually bring."

Substack, Threads, and more

YouTube and creators are taking over the living room, and marketers like e.l.f. Beauty and St. Jude's fundraising organization ALSAC are leaning in, not wanting to be left behind.

"We have a lot of plans around long-form content, and that's a great place to show up," said Patrick O'Keefe, e.l.f. Beauty's chief integrated marketing officer. "We've been on YouTube for years. We're now looking at it from the lens of entertainment."

Others, like Poppi and Rothy's, are embracing the newsletter platform Substack to partner with creators. For some creators, Substack has become a way for them to get more personal with their biggest fans. That helps Poppi plan collaborations, said Sophia Sesto, Poppi's vice president of culture.

Yahoo has found value in Meta's Threads as a way to try out ideas in a lower-key environment before putting them out on bigger platforms, especially if it's jumping on a cultural moment and isn't sure how the effort will go over. When Taylor Swift released "Patient Zero," Yahoo riffed on it with a Thread that tied the "Os" in its name to the song.

"I think it's a little less precious over there, and it feels like a fun place to kind of gut check certain things, see how they'll perform," said Kemma Kefalas, Yahoo's senior director and head of Creative Lab. "It's just been a nice kind of litmus test for us."

Disney has especially found success with TikTok's Live feature, finding it a customizable way to build excitement for premieres. For "Zootopia 2," it had the viral squirrel character Nibs interview cast on the red carpet, while internet personality Carter Kench played host for the "Hannah Montana 20th Anniversary Special."

"Those moments work because we treated the platform as a canvas for a new kind of storytelling that connects directly to audiences in real time," Sadrzadeh said.

Brands are going direct

Platforms may always be a necessary part of doing business with creators. But going direct has become a bigger buzzword as many brands seek to bypass platforms entirely.

Keurig Dr Pepper, for one, wouldn't typically hire a creator through a platform's marketplace, said Lindsay Burstein, senior director of integrated social and communications, using TikTok as an example.

"We would hire the creator, have them post on TikTok. Then we have the ability to use that content and distribute it across multiple channels, but slice it up in different ways that make sense for that channel."

Influencers spent a long time trying to convince marketers to take them seriously. This year, marketers are expected to spend $44 billion with creators, more than tripling in five years, per the Interactive Advertising Bureau.

As brands increasingly treat creators as long-term partners, they're engaging with them earlier in the marketing process.

Yahoo's approach is to find creators who are entertaining and figure out how to insert itself into their work, rather than vice versa, as it did with TV persona Kyle Cooke to promote its new Yahoo Weather app.

"We're working with them for the entertainment that they bring to people, and we'll Yahooify it," Kefalas said. "Our briefs are often loose in those regards. We're not doing a lot of 'talk to camera, promote products' kind of thing. We've gotten a lot of positive feedback from creators that they've loved that opportunity to just do what they do best."

• The Tiger Sisters shared advice on when to keep friendships and when to walk away.
• Cherie and Jean Luo are applying their signature analytical approach to emotional topics.
• They laid out four factors to consider in evaluating friendships.

The Tiger Sisters became top business podcasters by sharing their educational and career experience at Stanford, Goldman Sachs, and more. Now, the self-described "Silicon Valley and Wall Street big sisters" are applying their mindset to friendships.

"I think everyone privately has gone through a friendship breakup at some point in their life, whether it's passive or active," Cherie Luo said in an interview. "And it's something that doesn't get enough attention because when we think relationships, we mostly think the romantic breakup is the most traumatic."

In a three-part series on the subject this month, the hosts broke down how they audit relationships with pals and when they know it's time to break up with a friend.

The sisters, who just joined the Vox Media Podcast Network, started out in 2024 by sharing lessons from their school and work experiences and have since introduced more emotional content. It's a bet that their formula can extend to a broad array of topics and give them more staying power as they aim to grow into a larger media company.

"We did start Tiger Sisters with a very, very business-oriented approach," Jean Luo said. "It was more so our audience that kept asking us like, 'Well, what about how does this apply to friendships? Who are you guys dating? What's going on in your relationships, in your dating lives?'"

In the friendship episodes, the sisters took a data-driven approach, drawing on academic research and layering in their own experiences rather than just venting about breakups.

"I think it's kind of in our DNA of, 'How do we make sense of something that could potentially be very messy and emotional and bring a framework to help guide us through it?'" Cherie Luo said.

When to end a friendship

The sisters say people should consider four things when evaluating a friendship: who you are, where you are in your life, who the friend is, and how they'll fit into your life going forward.

"By providing this framework, it helps the listener and the Tiger fan take a step back from what is inherently an extremely emotional topic," Jean Luo said. "You can then decide if you want to go through an active or a passive dissolution."

Researchers have found that most friendship endings happen passively when people grow apart, Cherie Luo said. This leaves open the possibility that the friendship could be rekindled, whereas abrupt endings tend to be more acrimonious and permanent.

"It is less disruptive to a broader friend group," Jean added. "Friendships don't exist in a vacuum."

In the podcast, they also discussed alternatives to ending a friendship: distancing yourself or changing the role the friend occupies in your life.

They gave the example of a friend who was tired of always being canceled on by a pal. Rather than break up with them, they addressed the problem by double-booking them.

If you decide a friendship's run its course, you don't have to take the leap and break up with them immediately, the sisters said. It's important to take the rest of your life into account.

"Let's say you just had a baby, and you are starting a new job, and you are helping your parents with their health," Jean Luo said. "If there's a lot of things going on, maybe you actually don't need to address that friendship breakup right now. Even if the right decision is to end a friendship, there are a million different ways in which you can approach it."
