Key Takeaways

  • Learn to identify your business's 'one unit' - whether it's tacos sold, billable hours, or subscriber-months
  • Calculate the true cost of making each unit by separating variable costs from fixed overhead costs
  • Understand that you need to sell enough units to cover fixed costs before becoming profitable
  • Apply the CAC < LTV principle - customer acquisition cost must be less than lifetime value
  • Recognize that poor unit economics get worse with scale, not better
