Net Revenue Retention (NRR)
定義
NRR measures how revenue from an existing customer cohort changes over a year, including expansion, contraction, and churn. Above 100 percent means the base grows by itself.
資金調達における位置づけ
NRR above 100 percent is the strongest single signal in SaaS fundraising: the company would grow even with zero new sales.
よくある質問
What is a good NRR benchmark?
Above 100 percent is fundable, 110 percent-plus is strong, and 120 percent-plus is elite, typical of usage-based or expansion-heavy models.
How is NRR different from gross retention?
Gross retention caps at 100 percent and ignores expansion; NRR includes upsells, which is why it can exceed 100.
