How to nail your ICP using words they’ve already used

Most people overcomplicate defining their ICP. You don’t need another persona template, you need the actual words your best customers use.

A quick win is dropping your customer quotes, reviews, and call notes into an LLM and let it organise the chaos. It won’t replace real research, but it will give you a fast, surprisingly sharp starting point for your messaging.

Here’s a prompt to do exactly that. Copy, paste, and run it in your LLM of choice:

[paste reviews / call notes]

  1. Summarise the top frustrations, desires, and objections in a table.
    • Columns: “Theme”, “Exact customer phrasing”, “Why it matters”, “How often it appears (rough)”.
  2. Suggest 5 messaging angles that speak directly to those points.
    • For each angle, include: a name, a one-line description, and which themes it targets.
  3. Write 3 homepage headlines using those angles.
    • Prioritise clarity over cleverness. Max 10–12 words each.
