Paste one prompt into Claude with LeadOcean connected and size your fintech CTO list 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 fintech companies.
1. Call leadocean_list_enum_values for industry and pick Financial Services.
2. Call leadocean_count_leads with title Chief Technology Officer and CTO,
jobLevel C-Team, industry Financial Services and keywords fintech.
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 | Financial Services |
| keywords | fintech |
There is no fintech industry value. Financial Services is the closest exact string, so the prompt adds keywords, which matches the word in the person's own profile. Enum values are exact strings, which is why step 1 looks them up.
How many match
248 mailable people matched on 2 October 2026. Filters: title Chief Technology Officer or CTO, jobLevel C-Team, industry Financial Services, keywords fintech.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. It is a profile match, so a CTO who never writes "fintech" in their bio is missed. Run it again with words like payments or lending to widen the list.
The facets show 101 of the 248 sit at companies with 11-50 employees, and 35 are in IN, the largest country.
What you get back
Search rows carry the fields below, plus name, email status and company domain. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| Chief Technology Officer | 11-50 | Financial Services | IN |
| CTO | 51-200 | Financial Services | GB |
| Chief Technology Officer | 201-500 | Financial Services | US |
Variations
- Add "only companies with employeeRange 51-200 and 201-500" to reach fintechs big enough to buy tooling.
- Swap the title line for "VP Engineering, jobLevel VP" to reach the layer under the CTO.
- Change the keyword to "payments" and ask Claude to count again before searching.
