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.
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.
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.
Refundable if the first read does not move a budget decision. No contract, no annual lock-in, no pixel and no code change. It earns its keep at roughly €5K a month in paid spend, with a meaningful GA4 history; below that the model often cannot separate a channel from the noise, and we would rather say so than sell a number that cannot carry a decision.
