Survey tools measure everything.
We measure whether you’ll make it.
General feedback platforms treat product-market fit as one template among hundreds. FitSignal does one job — the Superhuman PMF method, end to end, with the benchmark integrity that makes the number mean something. And now licensed NPS®, for when fit is found.
Google Forms, Typeform
Free, but you hand-build the survey, chase the sends, dedupe in a spreadsheet — and still have no benchmark to compare against.
FitSignal
The canonical method, enforced integrity, linked love-and-blocker analysis, AI-ranked roadmap — at a price an indie builder can justify.
Survicate, SatisMeter & co.
Built for broad CX programs across many survey types. PMF is a template, not the product — the method’s guardrails are on you.
What makes FitSignal different
The canonical method, not a template
The exact 7 Superhuman questions, fixed wording, versioned. Your 52% means the same thing as the published 40% benchmark — because it’s measured the same way.
Benchmark integrity, enforced
Never the same user twice, eligibility windows, bounce exclusion — in the infrastructure, across email, widget, link and API. General tools leave this discipline to you.
Love linked to blockers
Click a benefit your core loves and see what blocks the almost-convinced users who want the same thing. No other tool connects the two — and it’s the heart of the method.
A ranked roadmap, with receipts
AI clusters improvement requests into themes and scores them with a transparent formula — frequency × severity × persona weight. Every theme links to verbatim quotes.
Priced for builders, not programs
A real free plan and a $29 Indie tier. CX platforms price for teams running year-round feedback programs — you need an answer, not a program.
PMF and licensed NPS®, one engine
When fit is found, switch on Net Promoter® waves — officially licensed, on the same customers, personas and integrations. One tool for the whole arc.
