Unit economics measures profitability per single transaction, customer, or unit — revealing whether the underlying business model works at scale. Key metrics: Contribution Margin per Unit, Customer Acquisition Cost (CAC), Customer Lifetime Value (LTV), Payback Period. A SaaS business with $1,000 CAC, $5,000 LTV, and 12-month payback has solid unit economics. Negative unit economics (each customer loses money) means scaling makes losses worse — common in venture-backed startups burning cash for growth. Validating unit economics before scaling is the venture capital playbook: prove profitable unit economics in small scale, then pour fuel on the fire.
