Afrexai Growth Engine

# Growth Engineering Mastery

> Complete growth system: experimentation engine, viral mechanics, channel playbooks, funnel optimization, retention loops, and scaling frameworks. From zero users to exponential growth.

## 1. Growth Audit — Where Are You Now?

Before experimenting, diagnose. Run this 8-dimension health check:

### Growth Health Scorecard

Rate each 1-5, multiply by weight:

| Dimension | Weight | Score (1-5) | Weighted |
|-----------|--------|-------------|----------|
| Product-Market Fit | 3x | __ | __ |
| Activation Rate | 3x | __ | __ |
| Retention (Week 4) | 3x | __ | __ |
| Referral/Virality | 2x | __ | __ |
| Revenue per User | 2x | __ | __ |
| Channel Diversity | 1x | __ | __ |
| Experiment Velocity | 2x | __ | __ |
| Data Infrastructure | 1x | __ | __ |

**Scoring:** 68-85 = Growth-ready. 50-67 = Fix foundations first. <50 = Stop growth spending, fix product.

### PMF Validation Gate

Do NOT invest in growth until these pass:

```yaml
pmf_gate:
  sean_ellis_test: "≥40% would be 'very disappointed' if product disappeared"
  retention_curve: "Flattens (does not trend to zero) by week 8"
  organic_growth: "≥10% of new users come from referral/word-of-mouth"
  nps: "≥30"
  qualitative: "Users describe product to friends without prompting"
```

**If PMF gate fails:** Stop. Go back to product. Growth without PMF = pouring water into a leaky bucket.

## 2. North Star Metric — Pick ONE Number

### Selection Framework

Your North Star Metric (NSM) must pass all 4 tests:

1. **Revenue proxy** — More of this metric = more revenue (eventually)
2. **User value** — Captures the moment users get value
3. **Measurable** — Can track daily/weekly with existing tools
4. **Influenceable** — Team actions can move it within 2-4 weeks

### NSM Examples by Business Type

| Business Type | NSM | Why |
|---------------|-----|-----|
| SaaS (B2B) | Weekly Active Teams | Teams = sticky, revenue follows |
| Marketplace | Weekly Transactions | Both sides getting value...

# Growth Engineering Mastery 🚀

Complete growth system for startups and scaling companies. From zero users to exponential growth through systematic experimentation, viral mechanics, and data-driven optimization.

## What This Skill Does

Turns your AI agent into a growth engineering partner that can:

- **Diagnose** your growth health across 8 dimensions with a scored audit
- **Design experiments** using ICE scoring and rigorous A/B testing methodology
- **Optimize every funnel stage** — acquisition, activation, retention, revenue, referral
- **Engineer virality** — K-factor optimization, referral program design, growth loops
- **Scale channels** — 12 channel playbooks with evaluation matrices and scaling criteria
- **Track metrics** — NSM framework, cohort analysis, weekly growth reviews
