Product overview

One loop, run honestly:
measure, understand, act.

Every part of FitSignal exists to serve a single loop — ask users the question that matters, understand what the answers mean, fix the right thing, and measure again. Here’s how the pieces fit.

1Measure

The exact Superhuman survey, delivered right.

The 7 canonical questions, unchanged — so your score is comparable to the published benchmark. Delivered by branded email or in-app widget, to users with enough usage to have an opinion. Never the same person twice per project.

2Understand

Not a wall of charts. An answer.

Three views, one story: your score against the benchmark, why your best users would be lost without you, and what’s holding back the users who almost feel that way. Filter all of it by persona, survey or period — averages lie, segments don’t.

3Act

Plug the signal into where you work.

New responses land in Slack as they arrive. Webhooks fire on every event with signed payloads. The REST API exposes customers, surveys, responses and analytics — so your score can drive dashboards, CRM fields, or whatever you build next.

4Repeat — and broaden

PMF is a practice, not a milestone.

Ship against the ranked blockers, then measure the next cohort and watch the trend. And the same engine runs licensed NPS® surveys — so once fit is found, you keep measuring the relationship.
