ICP & Buyer Persona Builder · Marketing Tool Stack

A vague ICP routes the wrong leads and waters down every message. This prompt forces a sharp one from the customers you already have.

What this isA prompt that turns notes on your best customers into a sharp ICP and one buyer persona.

You give itWhat you sell and notes on your strongest 5 to 10 accounts.

You get backAn account-level ICP, a buyer persona, three message angles, and signals to target.

Paste this into Claude, ChatGPT, or any capable model. Fill in the bracketed parts and it does the rest.

You are a B2B marketing strategist. Help me write a sharp ICP and one buyer persona for [COMPANY].

What we sell: [product in one line, and the core problem it solves].
Who buys today: [notes on your best 5 to 10 customers: industry, size, who signed off].
Where we win and lose: [any patterns you know].

Produce:
1. ICP (the account): industry, company size band, context or tech signals, and two or three disqualifiers. Tight enough to route leads against.
2. One primary buyer persona: role, what they own, the trigger that makes them look, top three goals, top three objections, and where they go for information.
3. Three message angles that would land with this persona, each in one sentence.
4. Three signals we could score or target on to find more accounts like this.

Be specific. If my input is thin, tell me exactly what to go find before you commit to the persona.

When to use it

When you are building scoring or targeting and need a definition tight enough to act on, or when sales and marketing disagree on who the good leads are.

How to use it

Feed it real notes on your best customers, not aspirations. The output is a starting point. Validate the persona against two or three recent closed-won deals before you route or target against it.
