The prompt
Find engineering managers at US companies whose website runs HubSpot.
1. Call leadocean_count_leads with technologies HubSpot, title
Engineering Manager, jobLevel Manager and country US.
2. Tell me the count and the filters you used.
3. Do not call leadocean_search_leads until I say go.What it resolves to
| Filter | Value |
|---|---|
| technologies | HubSpot |
| title | Engineering Manager |
| jobLevel | Manager |
| country | US |
The technologies filter matches a technology detected on the company website. It is a free-text name, not a closed list, so no enum lookup is needed. jobLevel and country are exact strings: Manager and US.
How many match
25,463 mailable people matched on 2 October 2026. Filters: technologies HubSpot, title Engineering Manager, jobLevel Manager, country US.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. Technology data covers about 7.8M crawled sites, so this is a floor, not every HubSpot company. The largest industry is Software Development at 8,561, and 13,355 sit at companies with 10001+ employees.
What you get back
Search rows carry the fields below, plus name, email status and company domain. These are placeholder values, not real records.

|---|---|---|---|
| Engineering Manager | 10001+ | Software Development | US |
| Engineering Manager | 201-500 | Financial Services | US |
| Engineering Manager | 51-200 | IT Services and IT Consulting | US |
Variations
- Add "only employeeRange 51-200 and 201-500" to skip enterprise teams with long buying cycles.

- Swap the title line for "Director of Engineering, jobLevel Director" to reach the layer above.
