## About

The Seaweed Bath Co launched in 2010 when founder Adam Grossman, seeking relief from chronic psoriasis, began formulating body-care products using wild-harvested bladderwrack seaweed from the coast of Maine. The company is headquartered in Boulder, Colorado, and operates as a closely held consumer packaged goods business rather than an allocator of external capital. Its product line has expanded from a single soap bar into a full range of shampoos, conditioners, lotions, and scrubs built around sustainably harvested seaweed as the hero ingredient. Grossman has steered the brand toward national omnichannel distribution. By 2018 The Seaweed Bath Co products were available in more than 12,000 retail locations across the United States, including mass-market chains such as Target and Walmart alongside natural-channel mainstays like Whole Foods Market and Sprouts Farmers Market (per the firm's official communications). The company also maintains a direct-to-consumer e-commerce operation. Unlike investment firms, its capital deployment takes the form of inventory builds, retail marketing, and new product development rather than portfolio construction across asset classes. The firm has remained independent since inception, with no disclosed outside institutional capital. Grossman continues to lead the business as CEO. In September 2022, the company further expanded its reach through a partnership with Thrive Market, the membership-based online retailer, extending its direct-to-consumer footprint beyond its own website (per Thrive Market, September 2022). Team size and revenue figures are not publicly disclosed by the firm. The structural differentiator for The Seaweed Bath Co is its ingredient-procurement model: the company directly harvests wild bladderwrack seaweed from the Gulf of Maine under a sustainable hand-harvesting protocol. This vertical integration into raw-ingredient sourcing sets it apart from competitors that purchase commodity seaweed extracts from third-party suppliers. Founder-led and independently operated since 2010, the firm maintains a governance structure typical of a private founder-controlled CPG company with no external board seats, no disclosed institutional minority investors, and no philanthropic arm separated from the operating business.

## Questions

### Who founded The Seaweed Bath Co and what was the origin story?

Adam Grossman founded the company in 2010. He developed the original formulations after discovering that wild bladderwrack seaweed from the Maine coast helped alleviate his chronic psoriasis symptoms. The business was bootstrapped from his personal experience, not spun out of an existing corporate R&D pipeline.

### Where does The Seaweed Bath Co source its seaweed?

The company harvests wild bladderwrack seaweed directly from the Gulf of Maine using a sustainable hand-harvesting method. This vertical integration into raw-material sourcing is a core operational distinction, as most competitors purchase processed seaweed derivatives from third-party suppliers.

### How widely distributed are The Seaweed Bath Co products?

As of its most recent disclosed figures, the brand is carried in more than 12,000 retail locations across the United States. Retail partners include Target, Walmart, Whole Foods Market, and Sprouts Farmers Market, supplemented by a direct-to-consumer e-commerce channel and the Thrive Market online platform.
