NICHING DOWN — '100 deep' beats '10,000 wide' in AI era

🎯 Why it matters

AI commoditizes ad cost — CAC competition is brutal. Deeper niche → lower CAC + higher LTV. Clients feel "this person specifically understands my problem" = pricing power. Niche is not constraint, it is leverage.

📊 ROI highlights

• CAC drops 50-80% (repeated touches within vertical)
• LTV up 2-3× (specific expertise = renewal)
• Referral rate up 5-10× (word-of-mouth within vertical)

⚠️ Common mistakes

• Pivoting niche too often — rebuilding credibility each time
• Niche too broad ("I serve all startups") — equals no niche
• Niche too narrow — TAM insufficient to sustain

✅ Action checklist

• This week: define niche = industry × problem × client size
• This month: rewrite all marketing collateral for niche
• Within 3 months: only accept niche clients (refuse others)
• Quarterly: niche review — TAM sufficient? Need adjacent expansion?
