BEFORE / AFTER

Lift AOV where shoppers already said “yes”

Stop buying more cold traffic when the cart can convert intent you already paid for.

BEFORE

Static drawer, missed margin

  • Cart shows line items only — no story for protection or gifting
  • Upsell ideas live in slide decks, not in the product
  • Finance sees CAC climb while AOV stays flat
AFTER

CartFlex in the drawer

  • Contextual tiles with inventory-aware rules finance approves
  • Experiment toggles with per-session lift, not vanity impressions
  • Margin recovered without another Meta learning phase

We didn’t need more traffic. We needed the cart to work harder. CartFlex moved the needle in days.

Finance finally trusts upsell exposure because guardrails are explicit. Creative can move fast again.

Every rejected upsell teaches the model. Weirdly addictive to watch the dashboard.
