Fit was the first question. Loyalty is the next.
NPS® surveys bring the world’s most widely used customer-loyalty measure into FitSignal — run on the same engine, the same personas, and the same once-per-cohort discipline that keeps your PMF benchmark honest. FitSignal is a licensed Net Promoter® vendor.
PMF finds the market.
NPS® keeps the relationship.
They answer different questions at different stages — and they’re better together. Both run on the same customers, personas and delivery channels you’ve already set up.
“Would you be disappointed to lose it?”
- Measures whether the market needs you
- Once per user, deep free-text evidence
- Best before and during finding fit
“Would you recommend it?”
- Measures how the relationship is going
- Recurring waves — quarterly or rolling — tracked over time
- Best once fit is found and you’re scaling the base
Everything you already trust, pointed at loyalty.
Score, trend & segments
The −100 to +100 score with promoter/passive/detractor distribution, tracked by wave and broken down by the same personas as your PMF data.
The “why” behind the number
An open follow-up on every response, fed through the same word clouds and AI theme analysis — so detractor pain ranks itself by impact.
Same channels & API
Email waves, in-app widget, public link, REST API and webhooks — NPS® rides the delivery and integration rails that already exist in your account.
