Kaelin Poulin, Founder Of Former Fastest Growing Women's Health Company In The U.S. Partners With Supra Human To Lead Women's Division

After building and exiting America's fastest-growing women's health and fitness company, Kaelin Poulin is returning to the industry with the company that coached her through a health comeback of her own.

SCOTTSDALE, Ariz., Oct. 5, 2026 /PRNewswire/ -- Kaelin Poulin, the entrepreneur behind the women's health and fitness company that reached No. 4 on the 2019 Inc. 5000, is returning to the industry she left behind. After making a fitness comeback of her own as a Supra Human client, she will now lead more high-performing women through the same coaching approach that helped her.

At 19, Kaelin lost 65 pounds, beginning a transformation that would shape much of what came next. She later became an IFBB Pro, earning her Pro Card in just two shows and setting a world record. Her journey in health and fitness eventually led to LadyBoss, the company she built alongside her husband, Brandon. Together, they grew LadyBoss to serve more than 700,000 women and reach No. 4 on the 2019 Inc. 5000 and No. 1 among B2C companies in America.

After selling LadyBoss, Kaelin stepped away from the industry to focus on homeschooling their children. Years later, after the birth of their third child, she found herself looking for a coach again.

Through each of her first two pregnancies, Kaelin gained and lost roughly 60 pounds, working with a coach each time. After her third, nearly two years passed before she hired a coach again. She didn't need more information about training or nutrition. She needed structure, accountability and an outside perspective that could make fitness work within the life she was living now.

That decision led her to Supra Human.

Kaelin had known founders John and Nineveh Madsen personally for years and watched the company take shape from the outside. But familiarity wasn't what made Supra Human the fit. By then, Supra Human had delivered more than 10,000 client transformations and earned back-to-back Inc. 5000 rankings through a coaching model architected around the realities of high-performing lives.

"The more I experienced it for myself, the more I kept thinking, 'Busy women with successful lives need this,'" Kaelin said. "High-achieving women carry so much responsibility in every other area of their lives. They need world-class support here, too."

What began as a fitness comeback with Supra Human was becoming a professional one.

From Client to Partner & Head of Supra Woman

The results Kaelin experienced through Supra Human did more than change her health. They began reconnecting her with an industry she had left years earlier.

For Nineveh, bringing what Supra Human had built to more women had long been close to her heart. After years spent building and architecting the company, she wanted the right partner leading the women's division, Supra Woman.

Kaelin brought experience on both sides of the equation: she had built and led a women's health and fitness company and had now experienced Supra Human's coaching firsthand as a client.

As Kaelin's progress continued, conversations expanded beyond her experience as a client to what a professional return to the industry could look like.

"I can't think of a better person to lead this from the front than Kaelin," said Supra Human CEO Nineveh Madsen. "She's a dynamic leader with the business acumen to run alongside me and a rare ability to connect with women. My focus is continuing to build Supra Human and advance the technology behind where we're going next. Kaelin is exactly who I want at the front as we bring that vision to more women."

Leading High-Performing Women Through Their Own Comeback

As Head of Supra Woman, Kaelin will lead high-performing women balancing demanding careers, businesses and families without lowering the standard they have for their health.

Her ability to connect with women has been a defining part of her career. Now, she brings that ability to a coaching model she first experienced as a client navigating the demands of her own fast paced life. Rather than standing on the other side of the transformation, she'll be in it alongside the women she leads,continuing her own journey while they pursue theirs through Supra Human's coaching.

She came to Supra Human to make a comeback of her own. Now, she'll help more women make theirs through the same coaching model she continues to experience firsthand.
