How It Works

ClearBrain identifies which of your users will upgrade or churn before they do so.

We build and retarget look-alikes for your users in minutes, without a single line of code.


Connect Your Data. No Code Required.

ClearBrain automatically connects to your email, analytics, or database platforms. We ingest your user traits and actions from analytics tools like Segment or Heap, and transform the underlying data for predictive modeling. This requires no engineering, so you can get set up in minutes.

Point-And-Click Predictive Audiences.

ClearBrain learns from your users’ past actions who is most likely to perform a future action. Use a point-and-click interface to build propensity scores for conversion or churn in minutes. Create predictive look-alike audiences of your high vs. low value customers, by the click of a button.
