Mosh, the brain health nutrition brand co-founded by Maria Shriver and Patrick Schwarzenegger, has raised $13 million in Series A funding led by Main Street Advisors. The round, with participation from Great Circle Ventures, Rogers Healy and Morrison Seger, PCG, and Tonic Ventures, reportedly fuels Mosh’s national grocery expansion, an upcoming nationwide Target rollout, and the launch of Mosh High Protein, a new bar with 20 g of protein, creatine, and Mosh’s Signature Brain Blend.

The investment comes as Mosh crosses 2,000+ U.S. retail doors, with the company’s retail channel on track to triple in 2026, driven by accelerating velocities at existing retailers, expanded facings, and the upcoming launch at Target. The brand has become a defining name in functional nutrition, built on a single idea: that the food people eat every day should nourish the organ they depend on most: the brain.

“When I co-founded Mosh, my hope was simple. I want to give people something delicious and genuinely nourishing that inspires them to take care of their brain, not just for today, but for the future,” says Shriver, Mosh co-founder and founder of the Women’s Alzheimer’s Movement at Cleveland Clinic, award-winning journalist, and eight-time New York Times bestselling author. “Every three seconds, someone in the world develops Alzheimer’s dementia, and two out of three of them are women. With every Mosh bar sold, we direct a portion of proceeds to fund Alzheimer’s research and women’s brain health, having raised more than $400,000 and funded three research grants to date. This is a recognition that millions of people are hungry for nutrition that supports brain health, and that Mosh is leading the way.”

“Our generation is rethinking what it means to take care of ourselves. You build the habits now that carry you forward,” states Schwarzenegger, co-founder of Mosh. “This Series A round puts Mosh on shelves at scale across national grocery stores and delivers category-first innovation like Mosh High Protein.”

“Scaling a consumer brand is fundamentally an execution story,” notes Jeff Gamsey, president of Mosh. “Over the last two years, we’ve built out the team, the supply chain, and the playbook to vault Mosh from breakout brand to a category-defining, durably profitable business.”

“It’s not often you see a brand carve out real white space in a category as crowded as nutrition, but Mosh has done that while building a brand people genuinely love,” said Paul Wachter, founder and CEO at Main Street Advisors. “Maria and Patrick are tapping into a major shift in how people think about brain health, and we're proud to partner with them as they continue to grow.”

The funding arrives at a notable moment for brain health nutrition. The U.S. brain health supplements market is projected to nearly double from $3.56 billion in 2024 to $6.8 billion by 2030, according to Grand View Research, while high-protein bars continue to be one of the fastest-growing segments of the bar category. Yet according to the Alzheimer's Association's 2026 Facts and Figures report, 99% of Americans value brain health equally or more than physical health, while only 9% say they know a lot about ways to maintain it. Mosh reportedly was built to close that gap, pioneering a brain health nutrition category in a bar aisle that has long been dominated by legacy protein and energy claims.
