Specialized Business Metrics

The five metrics every founder and operator should be able to defend on a whiteboard — unit economics, customer lifetime value, burn rate and runway, market sizing, and pricing strategy. Built on real models (Pareto/NBD, BG/NBD, Van Westendorp price sensitivity, default-alive math), not generic templates.
