Claude Prompt: Find Marketing Directors at Companies Using HubSpot

Paste one prompt into Claude, or any MCP client, with LeadOcean connected and get a sized list of marketing directors at companies whose website runs HubSpot. Connect https://api.leadocean.io/mcp first. Setup is on the MCP page.

The prompt

Find marketing directors at US companies whose website runs HubSpot.
1. Call leadocean_count_leads with technologies HubSpot,
   jobFunction Advertising & Marketing, jobLevel Director 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

The technologies filter matches a technology detected on the company website. It is a free-text name, not a closed list. jobFunction and jobLevel are closed lists, and the strings above are exact. Filtering on jobFunction catches titles such as Director of Demand Generation that a title keyword would miss.

How many match

45,014 mailable people matched on 2 October 2026. Filters: technologies HubSpot, jobFunction Advertising & Marketing, jobLevel Director, country US.

Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. Run it again before each campaign, since the number moves as sites change their stack. Technology data covers about 7.8M crawled sites, so this is a floor, not every HubSpot company. The largest industry is Software Development at 6,249, and 10,272 sit at companies with 10001+ employees.

What you get back

Search rows carry the fields below. These are placeholder values, not real records.

Variations

• Add "only companies with employeeRange 51-200 and 201-500" to target mid-size marketing teams.
• Add "industry Software Development" and count again to see the SaaS slice.
• Swap jobLevel Director for jobLevel VP to reach the layer above.

Records it spends

leadocean_count_leads is 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.
