Paste one prompt into Claude with LeadOcean connected and size your SaaS 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 SaaS companies with 51-200 employees.
1. Call leadocean_list_enum_values for industry and pick the software values.
2. Call leadocean_count_leads with title Founder and Co-Founder,
industry Software Development and Computer Software,
employeeRange 51-200.
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 | Software Development, Computer Software |
| employeeRange | 51-200 |
There is no SaaS industry value. Software Development and Computer Software are the closest exact strings, so the list covers software companies of every model. Enum values are exact strings, which is why step 1 looks them up.
How many match
8,534 mailable people matched on 2 October 2026. Filters: title Founder or Co-Founder, industry Software Development or Computer Software, employeeRange 51-200.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free.
Add the keyword SaaS and the same count drops to 306, because only profiles that use the word match. Use that version when you need a tight list. Keep the title filter. The seniority filter returns a different total for founders, so it is not a substitute.
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 | 51-200 | Software Development | US |
| Co-Founder | 51-200 | Computer Software | GB |
| Founder and CEO | 51-200 | Software Development | CA |
Variations
- Add "keywords SaaS" and ask Claude to count again, which narrows the list to profiles that name SaaS.
- Add "country US" to keep US-based founders only, then ask for the count by country.
- Change employeeRange to "11-50" to reach early-stage SaaS founders who still run sales themselves.
Records it spends
The count and enum lookups are free. leadocean_search_leads costs 1 record per person returned, so a limit of 25 costs 25 records. Free gives you 1,000 records one-off with no card. Pro is $499 a month. See pricing.
