Investors in 2026 have stopped looking at top-line growth. They are looking at the health of your existing base.
Net Revenue Retention (NRR) has become the definitive indicator of product-market vibrancy. If your NRR is above 120%, you have a revenue engine. If it's below 100%, you have a leaky bucket—no matter how fast you acquisition is.
Building for Retention First
Retention starts at onboarding. If your users don't hit their 'Aha!' moment within minutes, your NRR is doomed. AI-native companies are using predictive telemetry to intervene before a user even realizes they are stuck.
