Free Claude skill / ICP Sharpener

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

ICP SHARPENER / SAMPLE OUTPUTSKILL ACTIVE

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.

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.
