HoldoutIQ

HoldoutIQ is a web app (with optional lightweight desktop agent) that helps growth teams measure true incremental impact of campaigns using simple, defensible holdout experiments. Instead of relying on last-click attribution or blended ROAS guesswork, it guides users to set up geo, audience, or time-based holdouts, monitors contamination, and calculates lift with confidence intervals. It connects to ad platforms and analytics sources, then produces executive-ready readouts: incremental revenue, CAC, payback, and sensitivity ranges. The product is intentionally narrow: it does not try to be a full marketing dashboard. It focuses on one painful question—"did this spend actually cause revenue?"—and makes the answer credible enough for finance and leadership. An AI assistant helps draft experiment plans, flags common design mistakes, and explains results in plain language without inventing numbers.
