How I work
I do not interview your current customers.
Almost every messaging process starts by asking the people who already bought. I think that is the wrong room. They are the ones the old narrative happened to work on, so all you learn is why the thing you already say worked on the people it already worked on. That is not research, it is a mirror.
The interesting customer is the one you do not have yet. The bigger contract, the better fit, the account you keep losing to somebody else. So the work starts by defining that person properly, then testing whether your words would survive first contact with them.
It is also why this does not take as long as it used to. AI shortens the research. It does not do the thinking, and the thinking is where this is won or lost. Anyone can put the question to a model. Knowing which question to ask, which answer is worth anything, and which one is the model agreeing with you because you led it there, is the part that still needs a guide. That is the part I do with you.
What this means in practice
Your existing customers still matter. They just come up as evidence of what has been working, not as the brief for what comes next.
You only do this once
What comes out is a framework, not a campaign. Every page, ad and email after it gets measured against the same sentence, so the next decision is quicker than the last one.
