Key Takeaways

  • Growth metrics without cost context create a dangerous blind spot that can lead to profitable-looking businesses going bankrupt
  • Every growth metric needs a 'shadow branch' that includes unit economics like COGS, gross margins, and true customer acquisition costs
  • ROAS alone isn't enough - you need to factor in cost of goods sold and fulfillment costs to understand real profitability
  • Popular growth metric trees from companies like Duolingo are missing the cost side that determines actual business viability
  • Building analytics dashboards that ignore contribution margins skews decision-making toward vanity metrics over sustainable growth
