Instant Incrementality · causal measurement for teams who run MMM & geo-lift tests

Detect causal incremental ROI from data you already have.

Cassandra detects the incrementality of every budget change you've made, so you can calibrate your measurement (MMM + attribution) and make budgeting decisions that drive growth.

Detects causal lifts in about a minute

Causal proof, not attribution guesswork

Replaces months-long geo lift tests for calibration

Upload CSV · your geo panel

date, geo, <channel>_spend…, revenue

How to format your CSV⌄

One row per region, per day. You need:

• a date column
• a geo / region column
• one column per channel ending in _spend
• one outcome column (revenue or conversions)
• at least 1 year of history — we need enough past to find natural experiments

date	geo	google_spend	meta_spend	revenue
2024-01-01	California	1200	800	15400
2024-01-01	Texas	950	700	12100

Tip: 10+ regions and a few months of history give the cleanest causal read.
