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, Ecommerce, 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.

  description: First-party browser ES module (claire.mjs) a brand embeds to emit commerce telemetry to FERMAT. Exposes a window.fermat
    command queue with init, track and status methods, and six documented events — page_view, view_product, add_to_cart, remove_from_cart,
    begin_checkout and purchase — each with a published field schema. Lazily loads a session recorder for replay, heatmaps
    and scroll-depth analysis when recording is enabled in the pixel config. Installed via a direct script tag or Google Tag
    Manager; Shopify stores use a separate native path.
