1. Identifying and mapping growth loops
2. Building quantitative models for loop efficiency
3. Sequencing loops along the S-curve
4. Optimizing for compounding effects

Core Concepts

What is a Growth Loop?

A growth loop is a closed system where outputs of one cycle become inputs of the next, creating compounding growth:

┌─────────────────────────────────────────────────────┐
│                   GROWTH LOOP                        │
│                                                      │
│    ┌─────────┐     ┌─────────┐     ┌─────────┐     │
│    │  INPUT  │────▶│ ACTION  │────▶│ OUTPUT  │     │
│    └─────────┘     └─────────┘     └────┬────┘     │
│         ▲                               │          │
│         │         REINVESTMENT          │          │
│         └───────────────────────────────┘          │
└─────────────────────────────────────────────────────┘

Loop Types

Execution Flow

Step 1: Map Current Growth Sources

analytics.get_metrics({
  metrics: [
    "acquisition_by_channel",
    "viral_invites_sent",
    "content_organic_traffic",
    "paid_cac",
    "sales_pipeline"
  ],
  period: "90d",
  breakdown: "source"
})

Step 2: Identify Loop Candidates

Viral Loop Indicators:

• Users create shareable output
• Multi-player features exist
• Word-of-mouth present
• Collaboration is core

Content Loop Indicators:

• Users generate searchable content
• Domain has search demand
• Content compounds over time
• UGC potential

Product Loop Indicators:

• Network effects possible
• Data improves with usage
• Integrations drive adoption
• Templates/marketplace potential

Step 3: Design the Loop

Viral Loop Design

┌──────────────┐
│  New User    │
└──────┬───────┘
       │
       ▼
┌──────────────┐
│  Activation  │ (Aha moment)
└──────┬───────┘
       │
       ▼
┌──────────────┐
│ Create Value │ (Shareable output)
└──────┬───────┘
       │
       ▼
┌──────────────┐
│   Invite     │ (Organic sharing)
└──────┬───────┘
       │
       ▼
┌──────────────┐
│ Friends Join │ ──────┐
└──────────────┘       │
       ▲               │
       └───────────────┘

Key Metrics:

• K-factor (viral coefficient) = invites × conversion rate
• Cycle time = time for one complete loop
• Branch factor = variations of sharing

Content Loop Design

┌──────────────┐
│ SEO Traffic  │
└──────┬───────┘
       │
       ▼
┌──────────────┐
│  Signup      │
└──────┬───────┘
       │
       ▼
┌──────────────┐
│ Create/Use   │
│   Content    │
└──────┬───────┘
       │
       ▼
┌──────────────┐
│ Index/Rank   │ ──────┐
└──────────────┘       │
       ▲               │
       └───────────────┘

Key Metrics:

• Content velocity
• Indexation rate
• Rankings improvement
• Traffic-to-signup ratio

Paid Loop Design

┌──────────────┐
│  Ad Spend    │
└──────┬───────┘
       │
       ▼
┌──────────────┐
│  Acquire     │
│    User      │
└──────┬───────┘
       │
       ▼
┌──────────────┐
│  Monetize    │
└──────┬───────┘
       │
       ▼
┌──────────────┐
│  Reinvest    │ ──────┐
│   Profit     │       │
└──────────────┘       │
       ▲               │
       └───────────────┘

Key Metrics:

• CAC payback period
• ROAS (Return on Ad Spend)
• Reinvestment rate
• Diminishing returns threshold

Step 4: Quantitative Modeling

Loop Efficiency Formula

Loop Efficiency = (Output Value × Conversion Rate) / Input Cost

Compounding Math

For viral loops:

Users at time t = Initial × K^(t/cycle_time)

Where K = viral coefficient
K = invites_per_user × invite_acceptance_rate

K-factor interpretation:

• K < 1: Loop decays (needs external fuel)
• K = 1: Loop sustains (no growth/decay)
• K > 1: Loop grows (true virality)

For content loops:

Traffic at time t = Base + (Content_pieces × Avg_traffic × (1 - decay_rate)^t)

For paid loops:

ROI = (LTV × Conversion_rate - CAC) / CAC
Reinvestment_factor = LTV / CAC

Step 5: S-Curve Sequencing

Growth loops follow S-curves:

Users
  │                           ┌──────────────
  │                         ╱│  Saturation
  │                       ╱  │
  │                     ╱    │
  │                   ╱      │  Growth
  │                 ╱        │
  │               ╱          │
  │             ╱            │
  │           ╱              │
  │         ╱                │  Early
  │       ╱                  │
  │─────╱────────────────────┴────────────▶ Time
      Launch

Sequencing Strategy:

analytics.get_cohort({
  metric: "acquisition_source",
  period: "monthly",
  cohorts: 24
})

Step 6: Generate Loop Design

ui_kit.panel({
  type: "loop_design",
  title: "Growth Loop Design",
  content: {
    loopDiagram: loopVisualization,
    quantitativeModel: {
      efficiency: loopEfficiency,
      kFactor: viralCoefficient,
      cycleTime: averageCycleTime,
      projectedGrowth: growthProjection
    },
    sequencing: sCurveRecommendation
  }
})

Guardrails

• Only use whitelisted tools from skill configuration
• Validate loop assumptions with real data
• Don't assume K > 1 without evidence
• Account for saturation in projections
• Consider negative loops (churn, bad WOM)
• Test loop mechanics before scaling investment
• Track actual vs projected performance
• Sequence loops based on stage, not preference
