Across the ARR cube · Day 23 of 60
Strong retention headline, but expansion is masking churn — the metric to underwrite carefully.
  • NRR 117% is best-in-class — but 23 pts of expansion are covering a 6% logo-churn rate that’s drifting up.
  • GRR-with-downsell is 89%. The gap to NRR is the story: durable growth depends on slowing churn, not just expanding.
  • Gross margin 71%, CAC payback 19 mo. Services-heavy mix and lengthening payback temper the efficiency picture.
