Incrementality, without the data team
Find out how much of your ad spend is actually driving net-new sales.
DeltaCause is a neutral co-pilot for growth marketers. It guides you from a directional gut-check, to a properly designed test, to an honest read of the result — and it never touches your ad accounts.
Reality Check
Paste your reported ROAS and ad mix. Get a directional read on how much of that return is likely genuinely incremental — and how much spend may be at risk.
Run a Reality Check →Test Designer
Turn your baseline rate, target lift, and traffic into a properly powered test plan: sample size, duration, detectable effect — plus an honest go / amber / no-go fit gate.
Design a test →Lift-Test Reader
Already ran a test? Paste the result. Get a plain-language verdict on significance, recomputed iROAS and retrospective power, and honest flags when a result can't be trusted.
Read a result →Three kinds of numbers, never mixed
Every figure in the app declares where it comes from, so a benchmark estimate is never dressed up as a measurement.
Deterministic math from your inputs — sample size, power, duration, iROAS.
Reads a result you provide — p-value, confidence interval, significance.
A benchmark-based estimate, explicitly not a measurement (the free Reality Check).
