Paste one prompt into Claude with LeadOcean connected and size your Series A marketing director 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 marketing directors at Series A startups.
1. Call leadocean_list_enum_values for funding_type and confirm Series A.
2. Call leadocean_count_leads with jobFunction Advertising & Marketing,
jobLevel Director and employeeRange 11-50 and 51-200.
Leave fundingType out of the count.
3. Tell me the count and the filters you used.
4. Do not call leadocean_search_leads until I say go. When I do, add
fundingType Series A and search with a limit of 25.What it resolves to
| Filter | Value |
|---|---|
| jobFunction | Advertising & Marketing |
| jobLevel | Director |
| employeeRange | 11-50, 51-200 |
| fundingType | Series A (search only, not in the count) |
Enum values are exact strings, which is why step 1 looks them up. The count tool does not support fundingType, so the prompt counts without it and applies it at search time.
How many match
155,480 mailable people matched on 2 October 2026. Filters: jobFunction Advertising & Marketing, jobLevel Director, employeeRange 11-50 and 51-200.
This count is wider than your list. It covers every small company, not only Series A ones, so the fundingType filter at search time cuts it down. Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free.
The facets show 70,199 of the 155,480 are in US, 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 |
|---|---|---|---|
| Director of Marketing | 51-200 | Software Development | US |
| Marketing Director | 11-50 | Financial Services | GB |
| Director of Growth Marketing | 51-200 | Hospitals and Health Care | CA |
Variations
- Add "only people in country US" to build a single-market list.
- Swap the level line for "jobLevel VP" to reach the layer above the director.
- Change the funding line to "fundingType Seed" and ask Claude to search with a limit of 25.
