Install it in Claude as an Agent Skill, or copy it into ChatGPT, Gemini, or any assistant. Same method either way.

What this does and why it matters

Selling to everyone means resonating with no one. This skill builds a disciplined ideal customer profile (the firmographic and situational fit of the accounts worth pursuing) and the buyer personas within them (the humans who decide), so every rep and every campaign points at the same high-value target. Focus is the single biggest lever on outbound efficiency.

Inputs to gather

  1. The best current customers and why they are the best (retention, margin, speed to close, referrals).
  2. The worst-fit customers and what made them painful.
  3. The offer and the outcome it produces.

Method

1. Define the ICP from evidence, not aspiration

Derive fit criteria from the accounts that actually succeed: industry, size, business model, tech maturity, and the triggering situation that makes the offer urgent. Include disqualifiers (the traits of accounts to avoid), which are as valuable as the qualifiers.

2. Score fit

Turn the criteria into a simple tiered scoring model (A, B, C) so reps can prioritize a list quickly.

3. Build personas within the ICP

For each key role in the buying committee, capture their goals, the pains the offer relieves, what they fear, how they measure success, where they get information, and the objections they raise. Separate the economic buyer from the champion from the end user, since they buy for different reasons.

4. Translate to messaging angles

For each persona, one line on the hook that lands.

Output format

ALWAYS use:

# ICP and Personas: [Offer]
## Ideal customer profile (fit criteria)
## Disqualifiers (who to avoid)
## Fit scoring (A / B / C definitions)
## Personas
For each: ### [Role]
- Goals / how they are measured
- Pains we relieve / what they fear
- Where they learn / who they trust
- Objections
- Messaging angle
## Triggering events to watch for

Anti-patterns to avoid

  • An ICP so broad it excludes no one.
  • Personas built on demographics instead of goals and pains.
  • Ignoring disqualifiers.
  • Confusing the user with the buyer.

Example

A firm's best clients cluster as 50 to 200 person professional services firms that just added headcount. The ICP names that trigger, disqualifies sub-20-person shops, and builds separate personas for the managing partner (economic buyer) and the operations lead (champion).
