Usage signals win. Every time. Customer sentiment is a lagging indicator dressed up as a leading one. People will tell you they love your product in a survey and then quietly stop logging in three weeks later. The data doesn't lie, but people do, often unintentionally.
Here's the decision rule that changed everything for us: we call it "actions over adjectives." If a user's creation volume drops below 40% of their trailing 30-day average for two consecutive weeks, that account is flagged as at-risk regardless of what they said in their last NPS response or support ticket. We don't wait for them to tell us they're leaving. We treat the behavioral drop as the truth and the sentiment as noise until proven otherwise.
The cadence that made this actionable was a weekly Monday review where we look at cohort-level usage curves, not individual accounts in isolation. When you zoom out to cohorts, you start seeing patterns that individual sentiment data obscures. We noticed that users who hit a specific engagement threshold in their first 14 days renewed at 3x the rate of users who reported high satisfaction but created fewer than five videos. Satisfaction without depth of usage is a vanity metric.
One concrete example: we had a segment of users rating us 9 or 10 on satisfaction surveys, but their actual creation frequency was declining month over month. If we'd trusted sentiment, we'd have forecasted strong renewal. Instead, we treated them as at-risk, adjusted our forecast down, and built re-engagement flows targeting that exact cohort. The adjusted forecast ended up being far more accurate than the sentiment-based projection would have been.
The broader principle is this: what people do with your product is a confession. What they say about your product is a performance. Build your forecast on confessions.
