Paste one prompt into Claude with LeadOcean connected and size your fintech founder 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 founders at fintech companies.
1. Call leadocean_list_enum_values for industry and pick Financial Services.
2. Call leadocean_count_leads with seniority founder, 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 |
|---|---|
| seniority | founder |
| 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
1,211 mailable people matched on 1 October 2026. Filters: seniority founder, 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 founder who never writes "fintech" in their bio is missed. Add a second run with other words such as payments or lending. Each run is free, so compare the totals before you search.
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 |
|---|---|---|---|
| Founder | 11-50 | Financial Services | US |
| Co-founder and CEO | 1-10 | Financial Services | GB |
| Founder | 51-200 | Financial Services | SG |
Variations
- Add "only companies with employeeRange 11-50 and 51-200" to skip solo projects.
- Swap keywords to "payments" or "lending" to target one corner of fintech.
- Add "country US" and ask Claude to count again before searching.
