The 88% GRR Benchmark Is Gone: New Median Gross Revenue Retention Is 84% as Seats Convert to Agents

The SaaS CFO·medium signal

The SaaS CFO reports the median gross revenue retention benchmark dropped from 88% to 84% in 2026 — meaning even before any expansion, a $50M ARR company now sees a $2M hole open in its baseline every year purely from churn/downgrade. The driver is enterprises replacing seats with agents rather than adding them, which also breaks the NRR expansion motion that props up SaaS multiples. This is the quantified version of the 'seat compression' thesis, and it's a metric builders should watch in any incumbent they're betting against.
