Market validation vs. market diagnosis
Not rivals. Two moments on one timeline.
Validation and diagnosis are two moments on one timeline, not two rival methods
A timeline running left to right with two events marked on it, you build and you launch. Before the build, a green stretch is market validation, asking whether this should exist, answered with problem interviews, intent signals and adjacent buying behaviour, and carrying the risk that friendly signals read as proof. Between the two events the line is muted and marked building, because neither question applies while the work is being done. After the launch, a second green stretch is market diagnosis, asking why it is not moving now that it exists, answered from live demand shape, field crowding and execution leaks, and noted as the discipline few run honestly.
MARKLENS · SIGNAL
Two questions. Two moments.
Not rivals. Different evidence, because they are asked at different times.
Market validation
“Should this exist?”
Evidence: problem interviews, intent
signals, adjacent buying behaviour.
Market diagnosis
“It exists. Why isn’t it moving?”
Evidence: live demand shape, field
crowding, execution leaks.
YOU BUILD
YOU LAUNCH
BUILDING
RISK: FRIENDLY SIGNALS READ AS PROOF
THE DISCIPLINE FEW RUN HONESTLY
You cannot answer the second one with evidence gathered for the first.
ILLUSTRATIVE FRAMEWORK: NOT A DATASET
