Paste one prompt into Claude with LeadOcean connected and get a sized list of healthcare founders 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 healthcare companies in the United States.
1. Call leadocean_list_enum_values for industry and pick the hospital and health care values.
2. Call leadocean_count_leads with title Founder and Co-Founder,
those industries 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 | Founder, Co-Founder |
| industry | Hospital and Health Care, Hospitals and Health Care |
| country | US |
Both industry strings exist in the data, so the prompt passes both. Enum values are exact strings, which is why step 1 looks them up.
How many match
10,602 mailable people matched on 2 October 2026. Filters: title Founder or Co-Founder, industry Hospital and Health Care or Hospitals and Health Care, country US.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. The facets show 2,477 of the 10,602 sit at companies with 10001+ employees and 2,262 at companies with 1-10. A founder of a 5-person clinic and a founder listed at a health system are different buyers, so narrow with employeeRange before you write copy.
What you get back
Search rows carry the fields below. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| Founder | 1-10 | Hospitals and Health Care | US |
| Co-Founder | 11-50 | Hospitals and Health Care | US |
| Founder and CEO | 51-200 | Hospital and Health Care | US |
Variations
- Add "only companies with employeeRange 1-10 and 11-50" to reach early-stage founders.
- Swap the title line for "seniority founder". It is wider (32,599 mailable people on 2 October 2026), because the founder band also returns owners.
- Change country to GB and ask Claude to count again before searching.
