How do founders use AI to measure what is actually working across channels?

Platform dashboards each over-claim credit, so DTC operators triangulate with three methods: multi-touch attribution, marketing mix modeling, and incrementality tests, and AI platforms like Triple Whale's Moby, Northbeam, and Prescient now automate all three and answer plain-English questions about where the next dollar should go. For an early-stage founder the sequence is simple: clean conversion tracking first, post-purchase surveys second, and a paid measurement platform only once spend justifies $1,000-plus a month. The goal is knowing which spend is incremental, not which dashboard looks best.
