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 is listed with 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 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.
