Can a high NRR hide churn?
Yes. The Churn-Masking Illusion is detected by reading three numbers side by side: net revenue retention, gross revenue retention and logo retention. NRR healthy while the other two erode is the illusion in the data; recomputing NRR with the single largest account excluded settles it.
What it looks like in practice
The two medians the whitepaper carries, from Benchmarkit and Pavilion's 2025 benchmarks, show how much room the aggregate has: median NRR sits at 101% while median gross revenue retention sits near 88%. That spread is expansion covering churn, and a single expanding whale widens it further: every renewal cycle the company becomes more dependent on the one account it can least afford to lose.
What it is not
The illusion is not high NRR itself: a 120% NRR built on broad expansion across many accounts is exactly what the Develop gate exists to produce. The illusion is specifically the divergence, an aggregate carried by one or two accounts while the rest of the base churns.
Where it comes from
Named in The Revenue Debt You Cannot See as the Develop gate's primary failure mode.
