How do you track churn signals in B2B SaaS without annoying customers?

Behavioral signals are your best friend here — track things like login frequency drops, feature usage decline, and support ticket spikes passively through your product analytics (Mixpanel or Amplitude work well for this). Layer in a lightweight health score combining 3-4 of those metrics so you get early warnings without ever having to ask customers anything. If you do need qualitative input, a short 2-question in-app pulse survey triggered by usage drops feels way less intrusive than a cold outreach email.
