Growth isn’t accidental—it’s engineered. While traditional marketing relies on big budgets and broad campaigns, growth hacking uses creativity, data, and rapid experimentation to find scalable ways to acquire and retain users. It’s about finding product-market fit in your marketing, just as you do with your product.
Let’s explore how to turn users into evangelists and acquisition into a flywheel.
The Growth Mindset
Growth as a Science
Hypothesis-driven experimentation:
Hypothesis: "Adding social proof to landing page will increase conversion by 20%"
Experiment: A/B test with social proof badges
Metric: Conversion rate
Duration: 2 weeks
Result: 15% increase (close but iterate)
North Star Metric
Single metric that drives all growth efforts:
Facebook: Daily active users
Instagram: Daily story views
Stripe: Total payment volume
Superhuman: Emails processed per user
Cohort Analysis
Track user behavior over time:
Cohort: Users acquired in January
Week 1 retention: 70%
Week 4 retention: 40%
Week 12 retention: 25%
Insight: Focus on engagement in first 4 weeks

Viral Growth Mechanics
Viral Coefficient
How many new users each user brings:
K = (invites sent × conversion rate)
K > 1: Exponential growth
K = 1: Linear growth
K < 1: Sub-linear growth
Network Effects
Value increases with user base:
Direct network effects: Communication platforms
Indirect network effects: Platforms with complementary products
Data network effects: ML models improve with more data
Viral Loop Design
Hotmail approach: “PS: Get your free email at Hotmail”
Dropbox referral: Extra storage for both referrer and referee
Airbnb host incentive: Better visibility for hosts who refer
Measuring Virality
K-factor calculation:
Total new users = Organic + Viral
Viral users = Existing users × Invites per user × Conversion rate
K-factor = Viral users / Existing users
Conversion Rate Optimization
Funnel Analysis
Identify and fix drop-off points:
Visitors → Sign-ups → Trials → Paid customers
Conversion rates at each stage
Focus optimization on biggest bottlenecks
