"NRR is the one that most companies look at, most investors think of as the evaluation. The typical standard is you want to be well above 110% if you want to be an effective company. Top companies are well above that. Many recent AI companies have far exceeded that benchmark.
"NRR is made up of how many existing customers you retain (your gross revenue retention) plus your expansion revenue on top. So there are two main ways to drive it: improve retention, or drive expansion. Sometimes significant expansion can cover dollar retention losses you have.
"That's the big flaw with NRR: it allows you to cover your sins. It is not the best representation of how successful your customers are, and how well you are consistently making them successful — because you may have a segment that expands at a high clip. For example, large customers that have great expansion can be a massive injection of revenue that covers up the fact that mid-market and SMB clients are failing at an extremely high rate. Your NRR might look like you're growing well, but your actual logo retention, your actual GRR across your customer base — not just in a few customers — is doing extremely poorly.
"So if you're trying to diagnose what's actually going on, what's driving your NRR and how to be better at it, you have to look at the individual retention, logo retention, and expansion revenue per customer. Not just the blended NRR number."
Why it matters
Optimizing for NRR as a single number incentivizes companies to chase expansion in their easiest segment - typically large enterprise - while masking systemic failure elsewhere. Two companies with identical 115% NRR can have radically different underlying health: one has 90% GRR with 25% expansion from a healthy customer base; the other has 70% GRR offset by 45% expansion concentrated in five accounts. The first is durable. The second is fragile. NRR is a useful summary metric for boards and investors, but a dangerous operating metric in isolation.
Example
A $50M ARR company reports 118% NRR. Leadership treats this as a strong signal of customer health. A segment-level breakdown reveals: enterprise customers (top 20% of the base) at 140% NRR; mid-market at 95% NRR; SMB at 78% NRR. Two of the top five enterprise expansions are coming up for renewal and have begun competitive evaluations. If those two churn, the blended NRR drops to 92% overnight - and the broken mid-market and SMB segments are exposed without the enterprise cushion. The blended NRR was hiding the real picture all along.
