Paste one prompt into Claude with LeadOcean connected and size a list of manufacturing CTOs before you spend a single record. Connect the server at https://api.leadocean.io/mcp first. Setup is on the MCP page.
The prompt
Find CTOs at manufacturing companies in the United States.
1. Call leadocean_list_enum_values for industry and pick the
exact string for manufacturing.
2. Call leadocean_count_leads with title Chief Technology Officer and CTO,
jobLevel C-Team, that industry and country US.
3. Tell me the count and the filters you used.
4. Do not call leadocean_search_leads until I say go.What it resolves to
| Filter | Value |
|---|---|
| title | Chief Technology Officer, CTO |
| jobLevel | C-Team |
| industry | Manufacturing |
| country | US |
Industry values are exact strings, which is why step 1 looks them up. "Manufacturing" is the broad value. Narrower strings such as Machinery Manufacturing or Industrial Machinery Manufacturing exist and are counted separately.
How many match
381 mailable people matched on 2 October 2026. Filters: title Chief Technology Officer or CTO, jobLevel C-Team, industry Manufacturing, country US.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. The size breakdown is lopsided: 77 of the 381 sit at companies with 10,001 or more employees, while 129 sit at companies with 1-50. Add employeeRange before you write copy, because a CTO at a 20-person shop and a CTO at a global group buy differently. The count is a floor for the industry, since CTOs filed under narrower manufacturing strings are not in it.
What you get back
Search rows carry the fields below. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| Chief Technology Officer | 10001+ | Manufacturing | US |
| CTO | 51-200 | Manufacturing | US |
| Chief Technology Officer | 1001-5000 | Manufacturing | US |
Variations
- Add "only companies with employeeRange 501-1000, 1001-5000 and 5001-10000" to target plants big enough to run a technology team.
- Swap the title line for "VP Engineering, jobLevel VP" to reach the layer under the CTO.
- Replace industry Manufacturing with "Industrial Machinery Manufacturing" and ask Claude to count again.
