Key Takeaways

  • Marketplaces are harder to launch than e-commerce but easier to scale once network effects kick in
  • Focus on achieving liquidity by nailing a small, overlooked niche first, then expanding from there
  • Vertical marketplaces offer better user experiences but horizontal ones create larger venture-scale opportunities
  • Managed marketplaces trade scalability for quality control - jury's still out on which approach wins
  • Key metrics to optimize: lower customer acquisition costs, higher retention, and increased average order values
