Turn “we sell to B2B companies” into an ICP your team can act on.
A free Claude skill that interviews you about your best and worst customers, finds the pattern in the evidence, and outputs a one-page ICP with segments, triggers, disqualifiers, and the message angle for each.
FREE · BUILT BY GROW & CLOSE · WORKS IN CLAUDE + CLAUDE CODE
INPUT
Your website URL, plus 5–15 real accounts: best customers, worst customers, recent churns, recent closed-lost. Names optional, descriptions required.
OUTPUT
ICP: Series A–B PLG SaaS, 20–80 FTE, first marketing hire just landed · Buying triggers: new VP Marketing in seat <90 days; outbound tool ripped out · Disqualifiers: no dedicated budget owner; services businesses · Message angle: “your first marketing hire just inherited a backlog”
WHAT THE SKILL DOES
Method, not magic.
- 01Separates user, buyer, and champion instead of blending them into one persona
- 02Derives the ICP from real won/lost accounts, not founder aspiration
- 03Names 2–4 observable buying triggers so outbound has a reason to exist
- 04Forces 3–5 hard disqualifiers — a segment you can't say no to isn't a segment
- 05Flags which claims are evidence-backed vs. assumptions to test
Who it’s for: Founders and first marketing hires at B2B SaaS companies whose targeting feels broad, whose outbound reply rates are flat, or who are about to brief ads, outbound, or a landing page without a written ICP.

QUESTIONS, ANSWERED
Before you install.
01What is a Claude skill?+
A Claude skill is a packaged instruction set (a SKILL.md file) that teaches Claude a repeatable expert workflow. Install it once and Claude applies the methodology automatically whenever the task comes up — in Claude.ai, Claude Code, or the API.
02How is this different from just prompting ChatGPT for an ICP?+
A one-off prompt produces a generic persona. This skill encodes a methodology: it demands account-level evidence, splits user from buyer from champion, requires observable buying triggers, and refuses to output more than three segments. The constraints are the value.
03Do I need customer data to use it?+
No — with only a website URL it drafts an ICP and explicitly labels every part as an assumption with the fastest way to test it. With 5–15 real accounts it produces an evidence-backed profile.
04Is it really free?+
Yes. You get the .skill file in exchange for your email. No trial, no feature gate. It's how we show the quality bar of our positioning and messaging work.
