MOSH Raises $13M Series A to Scale Brain Health Nutrition Brand Nationwide

Protein bars still market themselves like a guy yelling through a Bluetooth headset at 5 a.m. More protein. More gains. More chest day philosophy from somebody named Brad who thinks creatine is a personality trait. Then MOSH shows up talking about brain health, cognitive wellness, lion’s mane, Cognizin, omega-3s, ashwagandha, vitamin B12, vitamin D3, and suddenly the whole category looks like it skipped class. That’s why the $13M Series A raised by MOSH lands differently.

Maria Shriver and Patrick Schwarzenegger did not build another celebrity vanity brand with polished packaging and empty calories hiding behind influencer lighting. They built a company rooted in something painfully real. Maria Shriver’s decades-long advocacy around Alzheimer’s and cognitive health came from watching Sargent Shriver battle the disease firsthand. Even the name MOSH comes from Maria Owings Shriver Health. That kind of mission cannot be manufactured in a conference room filled with agency decks and cold brew.

Patrick Schwarzenegger, serving as CEO, has quietly turned that mission into a real consumer business with traction, not just awareness campaigns dressed up as commerce. Jeffrey Gamsey, President and COO, brings the operational discipline needed to scale nationally without stripping the soul out of the brand. Angela Lukic Glandorf, SVP of Marketing, has helped shape a voice that feels informed instead of clinical, accessible instead of performative.

Main Street Advisors led the round, with participation from Great Circle Ventures, Rogers Healy and Morrison Seger, PCG, and Tonic Ventures. Smart capital tends to move before consensus catches up. Meanwhile MOSH already pushed nearly $10M in sales before this broader retail acceleration really kicked into gear. Consumers were already buying into brain health long before the market started treating cognitive wellness like the next frontier in nutrition.

Now comes the national Target rollout, and that changes the equation. Consumer behavior shifts when products stop feeling niche and start feeling normal. Putting brain-health-focused nutrition into everyday retail aisles changes who discovers it, who adopts it, and how fast the category matures. The brands that understand accessibility early usually become the company everyone else reacts to while competitors stay trapped debating “brand synergy” in Slack threads nobody wanted to join in the first place.

The backdrop matters too. The U.S. brain health supplements market is projected to grow from $3.56B in 2024 to $6.80B by 2030. Consumers are paying closer attention to memory, focus, cognitive performance, and long-term wellness because modern life has people mentally buffering like a laptop with 47 browser tabs open. MOSH feels less like a trend and more like a company arriving early to where consumer behavior is already headed.
