€99 once, excl. VAT. Keep Funnel.io; use us as the causal second opinion.

Side by side. Every fact sourced.

Short answer: Keep Funnel.io. 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 Funnel.io's data hub + optional Measure add-on (MMM / MTA / incrementality), 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 Funnel.io falls short

  • Attribution/measurement (Funnel Measure) is a paid add-on, not in the base plan
  • At $500K to $1M ad spend, Digital Measurement adds $2,250/mo on top of the base plan
  • Base plans billed annually
  • Measurement is quote-only on Business and Enterprise

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.
