Matched-market testing in your browser. Beta · Free
Upload or paste a CSV of a KPI by market and date. Plan a geo test, estimate incremental lift, and read rule-based next steps. Everything runs locally — nothing is uploaded to a server.
Columns: geo, date (YYYY-MM-DD), kpi. Daily or weekly. Header aliases such as market, sales or conversions are accepted. Lines starting with # are ignored.
Download the sample CSV (synthetic Canadian-metro-style markets, with a labelled demo lift on Vancouver).
If you enter spend and the KPI is revenue, iROAS is incremental units divided by spend. If the KPI is conversions, you will get incremental conversions per dollar instead — read the units carefully.

Join the waitlist / contact usMethods in brief: controls are ranked on the pre-period; the counterfactual uses constrained synthetic control (non-negative weights summing to 1), with a scaled-average or diff-in-diff fallback. Intervals use pre-period residual noise; placebo tests re-run the model on each unused control. Recommendations are rule-based.
