The Problem

Modern commerce media keeps promising “better attribution,” but most teams still cannot answer the hardest question cleanly:

did this campaign drive verified purchases, or just modeled likelihood?

That gap shows up everywhere:

  • premium CTV inventory is valuable, but post-campaign proof is often probabilistic;
  • retail-media data is usually trapped inside one merchant ecosystem;
  • agency and finance teams need independent validation, not only platform self-reporting;
  • brand teams struggle to compare click-heavy channels with upper-funnel commerce media;
  • proof for CFOs, procurement teams, and budget reviews is still assembled manually from dashboards, studies, and attribution vendors.

The result is a measurement workflow that feels expensive, fragmented, and politically weak exactly where ad budgets are getting scrutinized hardest.
