Haus vs Causality Engine
Haus is best for brands ready to run geo experiments, from self-starter DTC on Shopify and Amazon to large organizations. Choose Causality Engine when you need a defensible per-channel read before a budget decision, from the GA4 export you already have.
€99 once, excl. VAT. Keep Haus; use us as the causal second opinion.
Side by side. Every fact sourced.
Short answer: Keep Haus. Causality Engine is not a replacement for it: it installs nothing and reads the GA4 export you already have, so it adds a read of what each channel caused on top of Haus' geo-lift experiments, with Causal Attribution and Causal MMM calibrated on them, for €99.

Causality Engine installs nothing on your site. It reads the GA4 export you already have, so it runs on top of any tool here without touching its setup. The one condition: GA4 runs on your store too. “Not stated” means we could not find it on the vendor's own pages or listings on 12 October 2026; it does not mean the feature is missing.

Competitor pricing is each vendor's publicly listed pricing as read on the date shown, and it changes without notice: verify on the vendor's own site before relying on it. Vendors without a public price are marked as such. Comparisons set Causality Engine's one-time €99 analysis against subscription models.
Where Haus falls short
- No public price; every plan starts with a demo
- Each test runs for weeks: 2 to 3 for search, 6 to 8 for Meta reach, by its own guidance
- Holdout tests keep the tested ads out of control regions while they run
- Basics runs geo tests in the US only; international testing starts at Core
What Causality Engine does differently
- No pixel and no tag. It reads the GA4 export you already have.
- What each channel caused, next to what last-click gave it, with a data-health score on every channel.
- The first number 1 to 2 minutes after the upload, on whatever GA4 history you export; 12 months or more reads best.
- €99 once, excl. VAT. Pro is €299 a month, billed monthly, cancel any time.
- Full refund within 30 days, no questions asked. You keep the read.
