Churn signals hiding in the behavior you already track
Churn shows up in the report a month after the customer decided. Find the behavioral signals that predict it early enough to act on.
You are a retention analyst building an early-warning system. I will paste behavioral and churn data. Produce: A) THE SIGNAL SHORTLIST: behaviors in MY data that precede churn, each with the lead time it buys, how cleanly it separates churned from retained accounts using my numbers, and an explicit note where the sample is too small to trust. Never present a signal as predictive on a handful of cases. B) THE RISK TIERS: two or three tiers defined by combinations of those signals, each with its population size and what it would cost to treat — so the intervention is affordable at that volume. C) THE SAVE PLAYS: for each tier, the intervention matched to what the signal likely MEANS (dormancy, unmet expectation, price pressure, competitive switch), what NOT to do (the discount that trains the behavior), and the holdout design that proves the play worked. My data: [PASTE: behavioral events and frequencies, tenure, plan or purchase history, support contacts, churned versus retained cohorts, stated churn reasons if collected] Rules: Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it. Mark every claim I should verify in my analytics or source systems before it is published or presented. Never include customer personally identifiable information or client-confidential terms.
Why it works — Retention programs default to one blunt play — a discount at the moment of cancellation — because risk was never tiered and the signal's meaning was never asked. Matching the intervention to what the signal means separates saving a relationship from paying a customer who was staying anyway, and the holdout is the only thing that can ever tell those two apart.

The situation this prompt is built for: Churn shows up in the report a month after the customer decided. Find the behavioral signals that predict it early enough to act on. Below is exactly what to feed it and what comes back — no model-specific tricks, it runs the same in any chat AI.
Why this structure works
Retention programs default to one blunt play — a discount at the moment of cancellation — because risk was never tiered and the signal's meaning was never asked. Matching the intervention to what the signal means separates saving a relationship from paying a customer who was staying anyway, and the holdout is the only thing that can ever tell those two apart.
On Pro, pro personalization loads your event taxonomy so the signal shortlist is expressed in the exact events your product already emits.
When to use it — and when not to
Reach for it when
- Churn shows up in the report a month after the customer decided. Find the behavioral signals that predict it early enough to act on.
- You need the output in a shape you can forward as-is — the fixed structure above is the point.
Skip it when
- You don’t yet have the source material — the prompt is built to refuse to fake it. Its own guardrail: “Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it.” With nothing to work from, you’ll get a list of “not provided” flags, which is honest but not useful. Collect the inputs first.
- The task is genuinely one sentence long — a structured prompt earns its overhead when the output has parts. For quick one-off questions, just ask.

Common failure modes (and the fixes)
- Failure: letting the model drift past the prompt’s own guardrail — “Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
- Failure: letting the model drift past the prompt’s own guardrail — “Mark every claim I should verify in my analytics or source systems before it is published or presented.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
- Failure: letting the model drift past the prompt’s own guardrail — “Never include customer personally identifiable information or client-confidential terms.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
- Failure: accepting the first pass. Fix: reply with one line — “now cut everything that is generic to any company and keep only what is specific to mine” — the cheapest quality doubling available.
