Owned-data MTA stack. Or causal with intervals, no stack to build.
EYKData is a Rotterdam-based server-side multi-touch attribution platform with a strong technical thesis: your tracking, your BigQuery, your Looker Studio, no vendor lock-in. Stape-powered GTM, server-side click capture, consent-aware CAPI, and a published €399 Core / €529 Premium entry band by trailing-12-month gross sales. For an EU D2C brand that wants to own its measurement stack end to end, it's a legitimate path.
By their own words it's correlation-based at the entry tiers. Causal MMM and incrementality sit in their quote-only Advanced / early-access tier, and confidence intervals aren't surfaced anywhere we can verify. The core product also assumes you can stand up and maintain GTM + BigQuery + Looker, which is a real engineering commitment even with their server-side stack.
// EYKData answers what did the rule-based stack credit? → server-side MTA on owned BigQuery // Causality Engine answers what was actually causal, with how much certainty? → causal inference + confidence intervals
Same question, different answer. Often the opposite answer.
| Causality Engine | EYKData | |
|---|---|---|
| Method (entry tier) | Causal inference | Correlation-based (vendor's own wording) |
| Causal at entry? | Yes, default | No (Advanced is quote-only) |
| Confidence intervals? | Yes, on every read | Not surfaced |
| Stack to maintain | None | GTM + BigQuery + Looker Studio + CAPI |
| Price | €99 per read · €299/mo Pro | €399–€529+/mo entry; Advanced quote-only |
| EU / GDPR | Yes (Dutch, EU data residency) | Yes (Dutch) |
Which one is the right call for your situation.
Choose EYKData when
you want to own the underlying data architecture (your BigQuery, your Looker, your server-side tracking) and you have the team and patience to stand it up and maintain it. The owned-data story is real, the EU backend coverage is solid, and there's a genuine upgrade path to their causal tier if you can absorb a quote.
Choose Causality Engine when
you want causal inference with confidence intervals as the default output, not the premium services tier. You don't want to stand up GTM, BigQuery, and Looker Studio to get there. And you want it on your existing GA4 history for €99 a read, no subscription that scales with your sales.
No GTM build, no BigQuery, no Looker dashboards to commission. A €99 credit-card read versus standing up and maintaining a full server-side analytics stack just to reach the causal tier (which is quote-only).
The questions buyers ask about us vs EYKData.
- Is Causality Engine an EYKData alternative?
- For the causal-with-intervals question without standing up a BigQuery stack, yes. For owning your own server-side data pipeline end to end, EYKData is the explicit product for that.
- Do I need a BigQuery instance or GTM container?
- No. We run on your GA4 export (CSV). No data pipeline to set up.
- Both are Dutch. Why pick one?
- Pick by method and install cost. EYKData is correlation-based at the entry tier and assumes you can run a server-side analytics stack. We ship causal inference with confidence intervals as the base product, on a CSV upload, for €99. Both are EU-resident, both are GDPR-aligned.
Every causal vs MTA tool in one row each.
They track clicks. We measure cause. Four of these five tools are pixel or multi-touch-attribution dashboards on an annual contract; they reassign credit for conversions that already happened, and they need a script installed and maintained. Causality Engine measures incrementality, the sales a channel actually caused, from your existing GA4 and Shopify export, no pixel, with confidence intervals, for €99 a read. Different question, different bill, different install.
