The Hierarchy of Marketplaces — Introduction and Level 1

Summary

Sarah Tavel introduces a framework for building scalable and enduring marketplaces.

Who This Is For

Product Managers
Founders
Growth Marketers

Key Takeaways

  • Focus on creating buyer and seller happiness rather than chasing GMV as your primary metric
  • Start with a small, specific market (the 'thimble') and perfect happiness there before expanding
  • Use net revenue retention as a better measure of marketplace health than traditional vanity metrics
  • Understand that happiness is your true moat, not scale - even large incumbents are vulnerable to happier alternatives
