Growth Hacking

Viral coefficient K > 1 means exponential growth.

3. Improve Activation

Find the "aha moment" (first time user experiences core value):

• Map the onboarding flow step by step
• Find where >20% of users drop off
• Reduce steps to aha moment (remove friction)
• Guide users there faster (tooltips, email sequences, in-app nudges)

4. Retention Experiments

Tactics:

• Habit triggers: notifications at the right moment, not mass blasts
• Streak mechanics: daily engagement incentive
• Progress indicators: show users how far they've come
• Win-back campaigns: reactivate churned users with targeted message

Key Outputs

• Funnel analysis (AARRR metrics by channel)
• Viral loop design
• Activation experiment backlog
• Retention experiment results

Anti-Patterns

• Growth hacking before product-market fit (leaky bucket)
• Optimizing for acquisition while retention is poor
• Dark patterns (fake urgency, misleading copy) — destroys trust
• Running too many experiments simultaneously (can't attribute results)
