Evidence-controlled workflow
Project overview
See each validation checkpoint, current evidence strength, and the next move.
Validate the problem
Define the customer pain, check the evidence, and choose the riskiest assumption to test first.
Startup test journey
Start with a saved project, then move one step at a time.

Problem
Role + company type. The analysis scores every piece of evidence against this person.
Add the customer group you want to validate.
Describe their pain, not your product. If you catch yourself naming features, describe the moment the customer struggles instead.
Describe the customer problem before analysing.
This reads like a product description. Try describing the customer's struggle instead.
Add project context
These fields are optional.
Optional. Used as a label in your project list; the problem statement will be used if this is blank.
Optional. Problem analysis uses the customer and problem first; solution details are parked for later.
Add existing evidence
Optional. Most useful: complaints and workaround attempts.
Confirm the data and AI notice before analysing.
LeanNav uses AI practice interviews. Results are directional and should be validated with real customers before making build decisions.

Prioritize
Find the strongest evidence gap before you choose what to test.
Root assumption
–
How often it comes up
–
Tried to fix themselves
–
How frustrated they are
–
Would switch for a fix
–
Evidence you collect for any assumption below also counts toward this statement.
Recommended next test
Targeted evidence
