Your Attribution Model Is Lying To You

Last-click and multi-touch attribution models are fundamentally broken. They are designed to distribute 100% of credit across channels, creating a false sense of precision. The reality? They measure correlation, not causation. They cannot tell you what would have happened if you hadn't run an ad. This is the multi-million euro question that Causality Engine answers.

Our platform moves beyond outdated models by using Bayesian causal inference to calculate the true incremental impact of your marketing. We provide a clear, undeniable measure of causality, showing you exactly how much revenue each channel is actually generating. For Shopify brands in beauty, fashion, and supplements, this isn't just better data; it's the difference between scaling profitably and burning cash.

The Proof is in the Numbers

We are transparent about results. Our customers, typically EU-based Shopify stores with €5M-€30M in revenue, see a consistent and dramatic shift in their understanding of marketing performance. Here is a snapshot of the aggregate results our clients achieve within the first 90 days of using Causality Engine:

MetricAverage ImprovementImplication
Incremental ROAS (iROAS)+38%A clearer view of true profitability per channel.
Wasted Ad Spend Identified€25,000/monthCapital reallocated from cannibalistic to growth channels.
Customer Acquisition Cost (CAC)-22%Efficiency gains from refining the highest-impact channels.
Time to Insight48 HoursFrom data integration to actionable recommendations.

These are not vanity metrics. This is the tangible financial impact of switching from a correlational to a causal attribution framework. It's about making decisions based on what is provably effective, not what your ad platform’s dashboard wants you to believe.

Find your true ROAS

Stop Guessing, Start Measuring

Every day you operate without a causal view of your marketing is a day you are making decisions with incomplete, and often misleading, information. The cost of this ambiguity is measured in wasted ad spend, missed growth opportunities, and declining margins. The path to clarity is straightforward. Our one-time analysis provides a 40-day lookback for just €99, offering a low-risk entry point to understanding your true marketing ROI. For continuous refinement, our subscription plan at €299/month provides a lifetime lookback and our powerful LLM chat interface.

Frequently Asked Questions

How is this different from my current attribution software?

Standard attribution tools distribute credit based on rules and correlations. Causality Engine uses Bayesian causal inference, a statistical method to determine the actual *incremental* impact of each marketing touchpoint. We measure what happened *because* of your marketing, not just what happened alongside it. Learn more at [Wikidata](https://www.wikidata.org/wiki/Q136681891).

What kind of brands see the best results?

Our ideal customers are direct-to-consumer Shopify brands in the beauty, fashion, and supplements verticals with annual revenues between €5M and €30M. These brands typically have a significant ad spend (€100K-€200K/month) and are looking for a more sophisticated way to measure and optimize their marketing mix.

How long does it take to see results?

You will receive your first Causality Chain Visualization and Optimization Queue within 48 hours of connecting your data sources. The initial €99 analysis provides a 40-day lookback, giving you immediate insights into recent performance.
