Fermat

FERMÀT is an AI-native commerce platform that consolidates the shopper analytics, personalization, and experimentation stack into a single agentic system for direct-to-consumer and enterprise brands. It runs a closed loop — detect shopper behavior, recommend revenue-optimizing actions, generate adaptive storefront experiences and product pages, then feed performance signals back into detection — replacing tools like FullStory, Amplitude, Algolia, and Optimizely. FERMÀT integrates with ecommerce platforms including Shopify Plus, Salesforce Commerce Cloud, Adobe Commerce, and Oracle ATG via batch and streaming data syncs, and serves brands such as Glossier, GNC, Backcountry, AWAY, Travelpro, and TONAL. Surfaced as a portfolio company of Bain Capital Ventures, Greylock, and QED Investors.

Fermat publishes 1 API on the APIs.io network: Pixel v2. Tagged areas include Company, Commerce, E-Commerce, Personalization, and Analytics.

The Fermat catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Fermat’s developer surface includes engineering blog, support, changelog, documentation, API reference, getting-started guide, authentication, and 25 more developer resources.

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.

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. This rating is computed from github.com/api-evangelist/fermat: open an issue to ask a question, or submit a pull request to add artifacts.
