Growth Product Manager

Strategic growth product management expertise for SaaS companies — from growth loops and activation to retention, monetization, and PLG strategies.

Philosophy

Growth isn't about hacks. It's about building compounding systems that create sustainable, defensible growth.

The best growth product strategies:

  1. Systems over tactics — Growth loops compound; growth hacks don't
  2. Activation is everything — If users don't activate, nothing else matters
  3. Retention is growth — Churn kills; retained users compound
  4. Measure what matters — One north star metric, ruthlessly tracked

  • activation-*
    — First-time user experience, onboarding, time-to-value
  • retention-*
    — Engagement, habit formation, churn prevention
  • monetization-*
    — Pricing, upgrades, expansion revenue

The Growth Equation

Growth = Acquisition × Activation × Retention × Monetization × Referral

Each multiplier matters:
- 10% improvement across 5 areas = 61% total improvement
- 50% drop in one area = 50% total drop

Growth Model Overview

Anti-Patterns

  • Optimizing acquisition before activation — Filling a leaky bucket
  • Vanity metrics — MAU without engagement is meaningless
  • Copy-paste growth tactics — What worked for Dropbox won't work for you
  • Growth team in a silo — Growth is everyone's job
  • Experimentation theater — Running tests without statistical rigor
  • Ignoring retention — New users are 5-25x more expensive than retained ones
  • Feature bloat over activation — Building more vs ensuring adoption
