Talk about a résumé upgrade. Linda Yaccarino spent the last two years navigating Elon Musk's chaotic transformation of Twitter into X, and now she's moved on to become Tom Brady's boss at a telehealth startup. If nothing else, she knows how to work with demanding personalities.

Brady's New Game Plan

The seven-time Super Bowl champion has stayed busy since his second retirement from the NFL. He's got part ownership of the Las Vegas Raiders, a broadcasting gig with Fox Corporation (FOXA), and now he's diving into healthcare as the founding chief wellness officer at eMed.

The company specializes in GLP-1 weight management programs for businesses and individuals, offering access to FDA-approved weight-loss drugs while also tackling broader metabolic health issues like cardiovascular disease and diabetes management.

"We're working on something that I believe really matters," Brady said in a video announcement on social media. He emphasized that eMed is improving population health at scale and helping people feel better through accountability that keeps them on track.

"That mindset: discipline, consistency, showing up, define my career," Brady explained.

The NFL legend joins a growing roster of celebrities endorsing GLP-1 medications, including tennis champion Serena Williams. While the full details of Brady's role remain under wraps, his commercial appeal is well-established (just watch those Pizza Hut ads where he yells "hut" at customers). His Raiders ownership and NFL connections could open doors for future eMed partnerships.

The GLP-1 Revolution

Yaccarino isn't holding back on her assessment of the moment. "People underestimate the transformational impact that these GLP-1 medications have," she told CNBC. She described it as "the emergence of the biggest health intervention of maybe humanity's history."

That's ambitious language, but the market backs up some of the hype. Companies like Novo Nordisk (NVO) and Eli Lilly (LLY) have turned drugs like Wegovy, Ozempic, and Zepbound into blockbuster products, addressing diabetes, weight loss, and metabolic health at unprecedented scale.

For Yaccarino, the move into healthcare extends a career pattern of transforming industries that touch people's lives, from media to technology and now health. She believes the healthcare sector is "ripe for transformation."

What sets eMed apart, according to Yaccarino, is its focus on weekly check-ins, accountability, and personalization. "We are not a quick fix," she emphasized. That tough-love, accountability-driven approach is exactly why Brady chose to join, she said.

The company has real traction. eMed is backed by Aon plc (AON), which invested after eMed developed a subsidized GLP-1 weight management benefit program for Aon's U.S. workforce earlier this year. In just six months, over 1,200 employees enrolled and lost an average of 22.4 pounds. Those are meaningful results.

Leaving X Behind

Yaccarino served as CEO of X for roughly two years, steering the platform through Musk's turbulent acquisition and transformation into what she called "the global town square." She told CNBC she's "proud of what we accomplished during my time."

When asked about the moment Musk told advertisers to go f*** themselves, Yaccarino offered a diplomatic response: "I would've used different words." She added that transformation moves aren't always tidy.

In less than two years, Yaccarino has worked directly with the world's richest person and the man widely considered the greatest NFL player of all time. Not a bad stretch, even if the first job came with some memorable headaches. Now she's betting that healthcare transformation will be less chaotic than social media transformation. Time will tell if that's wishful thinking or strategic genius.
