Build your real ICP from your best customers

Claude

The skill plays the role of a go-to-market strategist inside Claude. Give it your best customers and it reads what they actually have in common (industry, size, geo, age, tech), who signed the deal, and how many lookalike companies are left to win. Everything runs on free FullEnrich search.

3. Share your best customers

Give 8 to 20 customer domains. Optionally add the LinkedIn URLs of the people who bought, the purchase dates, and the ICP you believe in today so the skill can compare. Under 5 customers there is no pattern, and the skill says so.

4. It reads the company pattern

For each dimension (industry, what they sell, headcount, HQ, founding year, revenue, tech), the skill shows the pattern and how many customers it covers, for example "8 of 12 are Software Development, 50-500 employees". Customers that break the pattern on 2 or more dimensions are named as outliers.

5. It reads the buyer persona

From the LinkedIn URLs you gave, the skill summarizes the title, seniority, time in role and previous role of the people who bought. Without URLs, it lists who holds the buying role at your customers, clearly labelled as candidates.

6. Get your ICP and your market

Your ICP in one sentence
The pattern table with coverage and outliers
The persona in 3 lines
The number of lookalike companies left to win, and the filter set as JSON

Built-in safeguards: every pattern comes with its coverage, and empty fields are reported as "no data", never as a pattern. Your existing customers are excluded from the lookalike count. Exporting the lookalikes costs 0.25 credit per company and only happens after you say yes.

What is next? the skill offers to find and enrich the persona at the top lookalike companies, score a list of accounts against this ICP, or export the lookalike companies.

Troubleshooting

Claude says the FullEnrich MCP is not connected

Open Claude settings and connect https://mcp.fullenrich.com/mcp. The skill resumes on the next message.

The skill says there is no pattern

You gave fewer than 5 customers, or they are very different from each other. Add more customers, ideally your best 10 to 20.

Revenue or HQ shows low coverage

FullEnrich has no data on those fields for some of your customers. The skill reports the coverage instead of guessing.

The persona is labelled "candidates"

Without the buyers' LinkedIn URLs, the skill can only list who holds the role today. Add the URLs to get the real persona.

The lookalike count looks very large

Industry and size alone match a lot of companies. The skill adds what your customers sell as keywords, and gives the count with the tech filter as a floor.
