They move your data. We conclude what was incremental.
Choose Funnel.io when your problem is moving marketing data reliably out of dozens of sources into a warehouse, BI tool, or conversion API. Stack Causality Engine on top when you want a causal conclusion on the data Funnel is moving.
€99 once, excl. VAT. Keep Funnel.io; use us as the causal second opinion.
Same question, different answer. Often the opposite answer.
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.
Compatible with Causality Engine: Yes. It installs nothing on your site; the one condition is GA4.

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.

The short version. What each one is for.
Funnel.io is a data-integration platform, not really an attribution tool. 590+ managed connectors moving marketing data into your warehouse, BI tools, and conversion APIs, with consumption-based flexpoint pricing. For a mid-market or enterprise team with an analyst, it's solid plumbing.
Their causal capability sits in a separate Funnel Measure add-on (MMM, MTA, incrementality), which is quote-only and aimed at brands spending $500k+ a month (reported ~$2,250/mo at that scale). The base $300/mo Starter and $600/mo Business plans are pipelines, not analyses. Some reviewers flag flexpoint bills as unpredictable and the platform as ETL-only at the base tier.
Which one is the right call for your situation.
Choose Funnel.io when
your problem is moving marketing data reliably out of dozens of sources into a warehouse, BI tool, or conversion API. That's its core job and it's good at it.
Stack Causality Engine on top when
you want a causal conclusion on the data Funnel is moving. We run on a GA4 export (which Funnel can produce), show what each channel caused next to last-click, and don't depend on hitting Funnel's $500k+ ad-spend floor to access causal methodology. Use Funnel for the plumbing, run us on the result.
Take it to your CFO.
Not a Funnel replacement. The pipeline still has a job; the causal-conclusion layer is what's missing at the base tier. A €99 read sits cleanly on top.
The questions buyers ask about us vs Funnel.io.
Is Causality Engine a Funnel.io alternative?
Not really. Funnel is a data pipeline; we're a causal attribution engine. We can run on data Funnel produces. They're complementary, not competitive.Do I need Funnel to use Causality Engine?
No. We accept a direct GA4 CSV export. Funnel just makes producing that export at scale easier for big teams.
Your platforms guess.
We run the math.
Upload a GA4 export and see what each channel caused, next to last-click, in 1–2 minutes. The read is yours to keep.
The free finding runs in your browser. Your file never leaves it. The full read is €99, refundable within 30 days, no questions asked. Prices exclude VAT.
