Summary

Growth hacking is a systematic, cross-functional approach to rapid experimentation across marketing, product, and engineering. Start with PMF, then identify your core growth lever and run high-tempo experiments prioritized by ICE (impact, confidence, and ease). The playbook covers four stages – acquisition, activation, retention, and monetization – each with specific tactics from viral loops and language-market fit to cohort analysis and pricing psychology. Never settle: get past local maximums by taking big bets.

Key Takeaways

Notes

1: The Method

1: Building growth teams

• Cross-functional, size varies; members:
  • Growth lead: leader, well-rounded
  • PM: “CEO of the product”
  • SWEs: empower them
  • Marketing specialists
  • Data analysts: combine data pools
  • Product designers
• Continuous cycle of 4 steps:
  1. Data analysis and insight gathering
  2. Idea generation
  3. Experiment prioritization
  4. Running the experiments
• Reporting structures:
  • Functional / product-led
  • Standalone growth team

2: Product market fit

• PMF: product needs to be a “must have”
• “Must have” survey
• Determine churn rate
• Leverage existing networks, talk to users
• MVT: minimum viable test
• Data lake / warehouse: centralize date

3: Identifying your growth levers

• Focus on highest impact
• Carefully choose metric
• “A good plan violently executed now is better than a perfect plan tomorrow”
• Data will tell you what but not why
• Make data, dashboards hyper-accessible

4: Testing at high tempo

• Have a consistent iteration cycle duration
• W/W/W/W/H
• Core metrics and necessary data analysis
• Experiments with quantitative hypotheses
• Have a database for experiment ideas
• ^ Prioritize: ICE: impact, confidence, ease
• Postmortem, publish, and keep a database

2: The growth hacking playbook

5: Hacking acquisition

• Reach and engage potential users
• Language market fit: describing to user
• Channel product fit: marketing channels
• Experiment with language, phrasing
• Optimize for specific channels, rather than going broad
• Channels:
  • Viral: social media, referrals, games, community, platform integrations
  • Organic: SEO, ASO, public speaking, email, partnerships, articles, merch
  • Paid: online + offline ads, influencers, sponsorships, retargeting
• 6 factors: cost, targeting, control, input time, output time, scale
• Keep searching for new channels
• Viral loops: viral coefficient > 1
  • Don’t use dark patterns
  • Leverage network effects

6: Hacking activation

• Funnel reports and conversion rates
• “What’s the one thing missing?”
• “How can we improve?”
• NUX: new user experience
  • Reduce friction (eg. SSO)
  • Flip the funnel: pre-login experience
• Positive friction: flow → lock-in
  • Eg. questionnaires, gamification
• Loyalty programs:
  • Status, access, power, stuff
• Triggers: emails, notifications, CTAs
  • Facilitator “”: ↑ motivation, ↓ ability
  • Signal “”: ↑ motivation, ↑ ability
  • Spark “”: ↓ motivation, ↑ ability
• 6 principles of persuasion:
  1. Reciprocity: more likely when in turn of a favor
  2. Commitment: (consistency) one action makes more likely to do next
  3. Social proof: look to actions of others
  4. Authority: look to those with authority
  5. Liking: more likely with those they like
  6. Scarcity: FOMO

7: Hacking retention

• Initial, medium retention periods
• Churn rate = 1 - retention rate
• Cohort analysis
• Engagement loop → habit formation
• Creative, non-tangible rewards
• Brand ambassador, elite status
• Strategies:
  • Recognition of achievements
  • Customization of the relationship
  • Coming soon
• Long-term retention:
• Steady stream of new features
• ^ prevents bloat, test changes independent
• Ramp up: progressive disclosure
• Resurrection: zombie customers
  • Don’t be too needy

8: Hacking monetization

• Map monetization funnel, find pinch points
• Segmented engagement, ARPU
• Personas of representative customers
• Recommendations: jacquard index
• Pricing: customer surveys for range
  • Pricing relativity: decoy product
  • Penny gap: upfront vs freemium
• Reciprocity: give before receiving (samples)
• Social proof: “X other people”
• Other principles of persuasion

9: A virtuous growth cycle

• Growth stall: never settle
• Get past local maximums by taking big bets
