Your CRM tells you who bought. LeadOcean tells you how many more like them exist. Connect https://api.leadocean.io/mcp first (setup is on the MCP page) and paste the prompt below.
The prompt
Here are my closed-won accounts from the last 12 months (CSV: company, industry, employees, country, deal size).
1. Find the pattern: which industry, headcount band and country hold most of the revenue?
2. Call leadocean_list_enum_values for industry and employeeRange and map the winning segment to exact values.
3. Call leadocean_count_leads for VP Sales buyers in that segment.
4. Tell me the count and the filters you used.
5. Do not call leadocean_search_leads until I say go.Dirty rows skew the pattern, so clean the export first. The CRM data hygiene guide shows how.
What it resolves to
| Filter | Value |
|---|---|
| jobLevel | VP |
| jobFunction | Sales & Business Development |
| industry | Software Development, Computer Software |
| employeeRange | 51-200, 201-500 |
| country | US |
This is the segment from a sample pattern: US software companies with 51 to 500 staff. Your CRM may point somewhere else, and Claude will map it the same way.
How many match
2,752 mailable people matched on 1 October 2026. Filters: jobLevel VP, jobFunction Sales & Business Development, industry Software Development or Computer Software, employeeRange 51-200 or 201-500, country US.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. Of the 2,752, 1,652 sit at companies with 51-200 employees.
Read the count against your closed-won list. If you have won 40 accounts in a segment that still holds 2,752 buyers, that segment has room. If the count is small, widen one filter at a time and count again.
What you get back
Search rows carry the fields below. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| VP of Sales | 51-200 | Software Development | US |
| VP, Business Development | 201-500 | Software Development | US |
| Vice President, Sales | 51-200 | Computer Software | US |
Variations
- Ask Claude to rank your segments by closed-won count and count the top three separately.
- Swap the buyer line for "Directors of Marketing, jobLevel Director" to size a second persona.
- Add "country GB" and compare the two counts before you pick a market.
