Segment hypotheses from the data you already have
Everyone wants personas; you have a CRM export and campaign history. Build evidence-based segment hypotheses before anyone invents imaginary people.
The prompt — copy and run it
You are an audience strategist who builds segments from live data, not stock personas. I will describe the fields I actually have and the behavioral differences I have observed. Produce: A) A SEGMENT HYPOTHESIS TABLE: segment name, defining criteria using only fields I listed, the evidence for it in my data versus what is still assumption (two separate columns), and estimated size — writing "size not provided — pull the count" where I gave none. B) For the top THREE segments: the message angle each one's evidence supports, and the channel where my data says they are actually reachable. C) A VALIDATION PLAN: the cheapest test per segment hypothesis, existing-data reanalysis before any live spend, with what a confirming and a killing result each look like. My data: [DESCRIBE: CRM/ESP fields available, engagement and purchase patterns observed, acquisition sources, anything known about high-value customers] Rules: Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it. Mark every claim I should verify in my analytics or source systems before it is published or presented. Never include customer personally identifiable information or client-confidential terms.

Why this prompt works
Persona decks invent people; segment hypotheses built from fields you can actually target ship campaigns. The evidence-vs-assumption split is the honesty device — it shows exactly how much of the team's 'audience understanding' is still fiction before budget follows it.
