Mammoth Brands

Mammoth Brands is the consumer packaged goods company formerly known as Harry's Inc., renamed in April 2025 to reflect a portfolio that now spans Harry's (men's shaving and grooming), Flamingo (women's hair removal and body care), Lume and Mando (whole-body deodorant) and Coterie (modern baby care). Founded in 2013 by Jeff Raider and Andy Katz-Mayfield and still privately held, it reported $835M in 2024 revenue. It runs no developer programme and publishes no OpenAPI, but two of its brands operate on Shopify and therefore expose a live, anonymous Model Context Protocol server plus a Universal Commerce Protocol merchant profile on their own domains — a real agentic-commerce surface with no documentation portal behind it.

Mammoth Brands publishes 2 APIs on the APIs.io network. Tagged areas include Company, Consumer Packaged Goods, Retail, E-Commerce, and Personal Care.

Mammoth Brands’ developer surface includes engineering blog, support, authentication, and 14 more developer resources.
