This is the metrics framework I wish I had when I was struggling to track the right KPIs at my Series A startup. It handles the math for LTV:CAC ratios, burn multiples, and net dollar retention, plus gives you stage-specific benchmarks so you know if your 15% monthly growth is actually good or concerning. The real value is in the detailed formulas for marketplace GMV tracking and SaaS quick ratios that most founders calculate wrong. It covers SaaS, marketplace, consumer, and B2B models with concrete targets like "NDR > 120% = best-in-class" instead of vague advice.
