Churn Risk Detector — find at-risk accounts before they leave — Claude Skill

Churn Risk Detector

Surface accounts at risk of churning before it's too late. Aggregates signals from support, communication, and usage patterns into a scored risk report with specific save actions.

Built for: Early-stage teams with no CS platform (no Gainsight, no ChurnZero). You have a spreadsheet of customers, a Slack channel, and a support inbox. This skill turns those raw signals into an actionable churn risk list.

When to Use

• "Which customers are at risk of churning?"
• "Run the weekly churn risk scan"
• "Flag accounts I should worry about"
• "Who haven't we heard from in a while?"
• "Produce a customer health report"

Phase 0: Intake

Account Data

1. Customer list — CSV or sheet with: company name, primary contact email, contract value (MRR/ARR), contract start date, renewal date (if known)
2. Product/service type — What are they paying for? (Helps calibrate expected engagement)

Signal Sources (provide what you have)

3. Support tickets — Export from Intercom, Zendesk, or email (CSV with: customer, date, subject, status, resolution time)
4. Slack channel history — Customer Slack channel or shared channel messages
5. NPS/CSAT scores — Recent survey results with scores and comments
6. Usage data — Any metrics you track: logins, API calls, features used, active users (CSV export)
7. Email/communication log — Last touchpoints per account (dates + context)
8. Billing data — Payment failures, downgrades, discount requests

Calibration

9. What does "healthy" look like? — Describe a healthy customer (e.g., "logs in daily, uses 3+ features, responds to emails within 24h")
10. Known churn reasons — Why have customers churned in the past? (helps weight signals)

Phase 1: Signal Extraction

1A: Support Signal Analysis

From support ticket data, calculate per account:

1B: Communication Signal Analysis

From Slack/email history:

1C: Usage Signal Analysis (if data available)

1D: Commercial Signal Analysis

Phase 2: Risk Scoring

Scoring Model

Each account gets a composite risk score (0-100):

Risk Score = Σ (signal_weight × signal_present)

Weights:
  Critical signal = 25 points each
  High signal     = 15 points each
  Medium signal   = 8 points each
  Low signal      = 3 points each

Score cap: 100

Risk Tiers

Phase 3: Save Play Generation

For each Red and Orange account, generate a specific save play:

Save Play Template

ACCOUNT: [Company Name]
RISK TIER: [Red/Orange]
RISK SCORE: [X/100]
MRR/ARR: $[X]

SIGNALS DETECTED:
- [Signal 1] — [Evidence: specific data point]
- [Signal 2] — [Evidence]
- [Signal 3] — [Evidence]

ROOT CAUSE HYPOTHESIS:
[1-2 sentences: What do you think is actually going wrong?
 E.g., "Champion left the company and new stakeholder hasn't been onboarded"
 or "They hit a technical limitation with [feature] that's blocking their primary use case"]

RECOMMENDED SAVE PLAY:
1. [Immediate action — e.g., "Schedule a call with [contact] this week"]
2. [Follow-up — e.g., "Send a personalized Loom showing how to solve [specific issue]"]
3. [Structural fix — e.g., "Assign a dedicated onboarding session for new stakeholder"]

TALK TRACK:
"[2-3 sentences the CSM/founder can use to open the conversation naturally,
 without saying 'we noticed you might be churning']"

ESCALATION TRIGGER:
If [specific condition] by [date], escalate to [founder/CEO call].
