National vitamin and supplement retailer

The catalog rewards repeat purchase. A protein tub, a multivitamin, a joint formula: each one runs out on a schedule, and every shopper is on a different one. Nothing on the site knew that. A returning customer landed on the same home page as a first-time visitor, and the reorder they came for sat four clicks away behind a search box.

Fulcrum read the purchase graph and the browse behavior together, then configured the full algorithm suite against them. Replenishment timing drives the home page and the post-purchase surfaces. Frequently Bought Together runs on the product page, where the stack matters more than the single product. Customers Also Bought carries the category pages, where education is doing most of the selling.

It reads like a merchandiser who knows every customer by name. Nobody on the client's team operates it. The suite recomputes nightly, adjusts in real time as behavior comes in, and the merchandising team approves placements rather than building them.
