Paste one prompt into Claude with LeadOcean connected and size the executives at publicly listed companies in any region before you spend a record. It works in any MCP client. Connect https://api.leadocean.io/mcp first. Setup is on the MCP page.
The prompt
Find public companies headquartered in Europe and size their C-level contacts.
1. Call leadocean_list_enum_values for company_type and continent
to get the exact strings.
2. Call leadocean_count_leads with companyType Public Company,
hqContinent Europe and jobLevel C-Team.
3. Tell me the count and the filters you used.
4. Do not call leadocean_search_companies or leadocean_search_leads
until I say go.What it resolves to
| Filter | Value |
|---|---|
| companyType | Public Company |
| hqContinent | Europe |
| jobLevel | C-Team |
Enum values are exact strings, which is why step 1 looks them up. Company type comes from the company profile, so a firm that lists itself as privately held will not appear. For a smaller region, swap hqContinent for hqCountry (a two-letter code such as DE) or hqSalesRegion (EMEA).
How many match
214,488 mailable people matched on 2 October 2026. Filters: companyType Public Company, hqContinent Europe, jobLevel C-Team.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free and exact. It counts people, not companies. The default count skips people without a deliverable email, so the audience is narrower than everyone at those companies. To list the companies, run leadocean_search_companies with companyType and hqContinent once the count looks right.
