When to Use

User needs rapid user acquisition, viral growth, or unconventional marketing tactics. Agent runs experiments, builds growth loops, and optimizes funnels for startups and products seeking exponential growth.

Quick Reference

Core Rules

1. Experiment Everything

• - Never assume what works. Test with real users
• Run 3-5 experiments per week minimum
• Kill losers fast, double down on winners
• Document every experiment: hypothesis, metric, result

2. Build for Virality

• - Every feature should ask: "How does this spread?"
• Viral coefficient (K) > 1 = exponential growth
• Types: inherent (product requires sharing), artificial (incentivized), word-of-mouth
• Reduce friction in sharing to zero

3. Optimize the Pirate Metrics (AARRR)

Stage	Metric	Focus
Acquisition	Traffic sources	Where users come from
Activation

4. Channel Saturation Strategy

• - Find ONE channel that works before diversifying
• Ride channels before they saturate (early TikTok, early Product Hunt)
• When CAC rises, move to next channel
• Own your audience (email list, community)

5. Speed Over Perfection

• - Ship in days, not months
• Ugly but working beats beautiful and delayed
• Learn from market, not from planning
• "If you're not embarrassed by v1, you shipped too late"

6. Data-Driven Decisions

• - Track everything from day 1
• Cohort analysis over vanity metrics
• A/B test with statistical significance
• Attribution matters: know what actually converts

7. Leverage Unconventional Tactics

• - Guerrilla marketing, stunts, PR hacks
• Piggyback on existing platforms and audiences
• Create artificial scarcity and FOMO
• Make users feel like insiders

Growth Traps

• - Scaling paid ads before product-market fit → burning cash
• Optimizing for signups instead of activation → leaky bucket
• Copying competitor tactics without understanding context → wasted effort
• Ignoring retention for acquisition → hamster wheel growth
• Viral features that annoy users → brand damage
• Vanity metrics (downloads, pageviews) over real metrics (LTV, retention)

Security & Privacy

This skill is instruction-only:

• - Does NOT access analytics, ad accounts, or email systems
• Does NOT require API keys or credentials
• Does NOT send data to external services
• All tactics are guidance for the user to implement manually

If implementing tactics requires external access:

• - User must explicitly grant access to specific tools
• Each integration should be reviewed separately
