MOSH, the brain health nutrition brand co-founded by Maria Shriver and Patrick Schwarzenegger in 2021, has raised $13 million in Series A funding led by Main Street Advisors.

The funding round helps fuel MOSH’s national grocery expansion, an upcoming nationwide Target rollout, and the launch of MOSH High Protein, a new bar with 20 grams of protein, creatine, and the MOSH 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.

“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,”  Maria Shriver, co-founder of MOSH, founder of the Women’s Alzheimer’s Movement at Cleveland Clinic, award-winning journalist, and eight-time New York Times bestselling author, said in a press statement.

“Every three seconds, someone in the world develops Alzheimer’s dementia, and two out of three of them are women,” she added.

The company directs a portion of proceeds to fund Alzheimer’s research and women’s brain health. To date, it has raised more than $400,000 and funded three research grants.

“This is a recognition that millions of people are hungry for nutrition that supports brain health, and that MOSH is leading the way,” Shriver said.

MOSH’s protein bars feature Cognizin Citicoline, along with its signature blend of lion’s mane, ashwagandha, omega-3s, and vitamins B12 and D3. 

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

According to Jeff Gamsey, president of MOSH, scaling a consumer brand is fundamentally about execution. “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.” 

Fueling and Funding the Next Chapter

According to MOSH, the Series A will fund four strategic priorities: 

• National Grocery Expansion: MOSH will continue scaling across national grocery, with an upcoming launch at Target adding to an expanding footprint across major retailers including Sprouts, Albertsons, Kroger, HEB, and more. 

• Category-First Product Innovation: MOSH is debuting MOSH High Protein, a new line of indulgent bars featuring 20 grams of protein, creatine, and the MOSH Signature Brain Blend. The line extends MOSH’s brain health platform with a formulation designed for consumers looking to support both cognitive and physical performance.

• Pioneering the Brain Health Category: In 2026, MOSH will fund a third research grant that will examine gut biomarkers present in people with cognitive decline or Alzheimer’s, with the goal of developing early nutritional interventions. 

• Team and Infrastructure: The company will grow its marketing, sales, and supply chain capabilities to support expanding retail scale.
