you can rebuild

  • Iframe and script tag rendering on checkout confirmation pages.
  • Dynamic coupon code generation and allocation pipelines.
  • Merchant reporting dashboard for impression, click, and conversion analytics.
  • Basic customer segmentation by cart value, location, and language.

what you lose

  • Access to millions of active, high-intent European shoppers on post-checkout pages.
  • Turnkey monetization of your own post-checkout confirmation page traffic.
  • Automated clearinghouse settlement between cross-promotional retail partners.
  • Pre-negotiated offer inventory from top European enterprise and mid-market brands.

real moats

  • A locked network of 5,000+ European e-commerce publishers generating massive cross-network traffic volume.
  • Contractual exclusivity agreements with large mid-market brands preventing multi-homing on alternative checkout networks.
  • Decades of historical conversion data optimizing offer matching algorithms across European consumer demographics.
