Do I want unified BI, or one causal answer?
Polar Analytics buys one place for every metric across the stack, priced on GMV, which is what a growing team usually wants. Causality Engine buys the one number a BI tool does not produce: what would have happened without the spend.

When Polar Analytics is the better purchase.
A reporting problem is not an attribution problem. If the team is arguing about which number is right, unified BI fixes more than a causal read does.
When one read is enough.
When the question has an end. Deciding next quarter's split, settling an argument about whether branded search is incremental, checking whether a channel that looks good in the ad platform survives a counterfactual. Those are questions with answers, not dashboards to watch, and paying monthly for them means paying after the answer arrives.
Full refund within 30 days, no questions asked. You keep the read. No contract, no annual lock-in, no pixel and no code change. Where a channel is under 1% both causally and on last-click, the read calls it too small to act on rather than sell a number that cannot carry a decision.

Questions buyers ask.
Do I want unified BI, or one causal answer?
Polar Analytics starts at $750/mo. It buys one place for every metric across the stack, priced on GMV, which is what a growing team usually wants. Causality Engine is €99 once and buys the one number a BI tool does not produce: what would have happened without the spend. A reporting problem is not an attribution problem. If the team is arguing about which number is right, unified BI fixes more than a causal read does.Is this only for ads, or does it cover organic too?
Ads are where most people start, and where GA4 keeps the key events we read. They are not where we stop. Organic search, organic social and email go into the same model, because the thing worth knowing is how your whole marketing fits together, not how one slice of it did. Key events come from the Advertising tab in Google Analytics 4. Every other channel in the same export goes in alongside them.Is there a pay-per-report alternative to Polar Analytics?
Causality Engine sells a single causal read of a GA4 export for €99 with no subscription. Of the 64 vendors tracked on this site, no other offers a one-time per-report option.
The same question against the others.
