High net revenue retention (NRR) rates, once a hallmark of robust B2B SaaS growth, have become increasingly rare in 2026, with median NRR for public companies dropping to around 108-110%, according to saastr.com. HubSpot maintains a flat 103% NRR, while Zoom’s enterprise segment has declined to 98%, indicating a contraction in customer spending. Only AI-native companies or those heavily repositioned toward AI budgets continue to achieve NRR above 120%.
This decline in NRR reflects a broader shift in the SaaS market dynamics. Previously, companies with NRR above 120% could rely on expansion revenue to double their size in under five years without acquiring new customers. However, the current environment reveals that high NRR can mask underlying issues such as stagnating new customer growth. PagerDuty exemplifies this trend: despite maintaining an elite 124-126% NRR through 2022, its customer count growth slowed significantly, eventually causing NRR to fall to 100% and impacting its stock performance.
The drop in traditional B2B SaaS benchmarks by 10-20 points highlights the challenges companies face in sustaining growth without AI-driven expansion. This shift underscores the importance of balancing retention with new customer acquisition to avoid hidden growth problems. Companies that rely solely on expansion revenue risk stagnation if new customer growth falters.
Looking ahead, SaaS firms must closely monitor both NRR and customer acquisition metrics to ensure sustainable growth. The evolving market suggests that firms will need to innovate their product offerings and sales strategies, particularly by integrating AI capabilities, to maintain competitive advantage and investor confidence in this changing landscape.
