PivotProof vs customer interviews: run the tank first, then go talk to humans.
Customer interviews are essential for willingness to pay. They work better when your assumptions are already explicit.
Use customer interviews when
You need real language, real workarounds, and evidence of willingness to pay from the people who would buy.
Use PivotProof when
You need to turn a vague concept into the sharp hypotheses worth testing with real people.
The verdict
Do not use AI as a replacement for customers. Use it to make your first 20 conversations more useful.
