Analyze my SaaS business metrics and identify the key levers: MRR: $[X], MRR growth: [%], Churn: [%], NRR: [%], CAC: $[X], LTV: $[X], Payback period: [months], Gross margin: [%]. Answer: 1) How do these metrics compare to [STAGE: seed/series A/series B] benchmarks, 2) Which metric most constrains my growth right now, 3) What does my LTV:CAC tell me about unit economics, 4) What churn rate would make this business uninvestable, 5) If I could only fix one metric in the next 6 months, which has the highest leverage, 6) What metrics matter most for my next fundraise.
