The Retention Curve
┌─────────────────────────────────────────────────────────────┐
│ RETENTION CURVE ANATOMY │
├─────────────────────────────────────────────────────────────┤
│ │
│ 100% ┌──────────────────────────────────────────────── │
│ │ ╲ │
│ │ ╲ Initial drop │
│ │ ╲ (Day 1-3) │
│ % │ ╲ │
│ │ ╲───────── Steep decline │
│ │ ╲ (Week 1-2) │
│ │ ────────────────────── Plateau │
│ │ (if healthy) │
│ 0% └────────────────────────────────────────────────▶ │

└─────────────────────────────────────────────────────────────┘
Execution Flow
Step 1: Build Retention Curves
analytics.get_cohort({
metric: "retention",
period: "monthly",
retentionDays: [1, 3, 7, 14, 30, 60, 90],
cohorts: 12
})
Step 2: Benchmark Analysis
Retention Benchmarks by Industry:
| Industry | D1 | D7 | D30 | D90 |
|---|---|---|---|---|
| Consumer Social | 25-40% | 15-25% | 10-20% | 5-15% |
| Consumer Utility | 20-35% | 10-20% | 5-15% | 3-10% |
| B2B SaaS | 80-95% | 75-90% | 70-85% | 60-80% |
| E-commerce | 15-30% | 10-20% | 5-15% | 3-10% |
| Gaming | 30-50% | 15-30% | 5-15% | 2-8% |
| Fintech | 40-60% | 30-45% | 20-35% | 15-25% |
Step 3: Cohort Analysis Deep Dive
Cohort Analysis Framework:
┌─────────────────────────────────────────────────────────────┐
│ COHORT ANALYSIS MATRIX │
├─────────────────────────────────────────────────────────────┤
│ │
│ │ Week 0 │ Week 1 │ Week 2 │ Week 4 │ │
│ ─────────┼──────────┼──────────┼──────────┼──────────┤ │
│ Jan '24 │ 100% │ 65% │ 48% │ 35% │ │
│ Feb '24 │ 100% │ 68% │ 52% │ 38% │ │
│ Mar '24 │ 100% │ 72% │ 58% │ 44% │ │
│ Apr '24 │ 100% │ 75% │ 62% │ ? │ │
│ │
│ LOOK FOR: │
│ - Improving cohorts over time (↑ product-market fit) │
│ - Specific cohort anomalies (what happened?) │
│ - Segment differences (who retains better?) │
│ │
└─────────────────────────────────────────────────────────────┘
Segmentation Dimensions:
| Dimension | Why Segment |
|---|---|
| Signup source | Channel quality |
| First action | Activation impact |
| Plan type | Value perception |
| Company size | Use case fit |
| Geography | Market differences |
| Feature usage | Engagement patterns |
Step 4: Churn Prediction Model
Churn Signals (Leading Indicators):
| Signal | Timeframe | Risk Level |
|---|---|---|
| No login 7+ days | Early | Medium |
| No login 14+ days | Mid | High |
| Decreased usage trend | Early | Medium |
| Key feature abandoned | Mid | High |
| Payment failure | Immediate | Critical |
| Support complaints | Mid | Medium |
| Competitor research | Early | Low-Medium |
| Admin account inactive | Mid | High |
Churn Prediction Formula:
analytics.get_metrics({
metrics: [
"days_since_last_login",
"usage_trend_7d",
"feature_breadth",
"support_tickets",
"payment_issues"
],
userId: context.userId
})
// Simplified Churn Score
churnRisk = (
(daysSinceLogin / 30) * 0.3 +
(1 - usageTrend) * 0.25 +
(1 - featureBreadth) * 0.2 +
(supportTicketTrend) * 0.15 +
(paymentIssues) * 0.1
)
// Risk Categories
if (churnRisk > 0.7) riskLevel = "critical";
else if (churnRisk > 0.4) riskLevel = "high";
else if (churnRisk > 0.2) riskLevel = "medium";
else riskLevel = "low";
Step 5: Engagement Scoring
Engagement Score Components:
| Component | Weight | Measurement |
|---|---|---|
| Frequency | 30% | Sessions per period |
| Depth | 25% | Features used, actions taken |
| Recency | 25% | Days since last activity |
| Growth | 20% | Usage trend direction |
Engagement Score Calculation:
engagementScore = (
normalize(sessionFrequency) * 0.30 +
normalize(featureDepth) * 0.25 +
(1 - normalize(daysSinceActive)) * 0.25 +
normalize(usageGrowth) * 0.20
) * 100;
Engagement Tiers:
| Score | Tier | Action |
|---|---|---|
| 80-100 | Power User | Advocacy programs, beta access |
| 60-79 | Engaged | Feature discovery, expansion |
| 40-59 | At Risk | Re-engagement campaign |
| 20-39 | Dormant | Win-back campaign |
| 0-19 | Churned | Resurrection campaign |
Step 6: Identify At-Risk Users
lifecycle.get_segment({
segment: "at_risk",
criteria: {
engagementScore: "< 40",
daysSinceActive: "> 7",
usageTrend: "declining"
}
})
Resurrection Strategies
Resurrection Timing
| Days Inactive | Classification | Strategy |
|---|---|---|
| 7-14 | At risk | Gentle reminder, value nudge |
| 15-30 | Dormant | Re-engagement campaign |
| 31-60 | Lapsed | Win-back offer |
| 61-90 | Churned | Resurrection campaign |
| 90+ | Lost | Periodic pulse, big updates |

Guardrails
- Only use whitelisted tools from skill configuration
- Use statistical significance for cohort comparisons
- Don't over-message churned users (respect unsubscribes)
- Segment resurrection campaigns by churn reason
- Track resurrection to re-churn rate
- Consider seasonality in retention analysis
- Don't conflate correlation with causation
- Validate churn predictions with actual churn
- Respect data privacy in user targeting
