Find companies by employee count

Filter on employeeRange or minEmployees and maxEmployees, then count the people you can reach. Sizing is free.

Both filters read the company headcount on file. Use a bracket for speed, or exact bounds when a bracket cuts in the wrong place. Then add the people you want at those companies.

The filter

A company with no headcount on file is never returned by minEmployees or maxEmployees. Bracket strings are exact: 51-200 works, 51 to 200 does not. Resolve them with leadocean_list_enum_values (name employee_range).

How many you can reach

Three live counts from leadocean_count_leads, run on 2026-10-01. Each uses the tool's default email statuses (verified, catch_all_valid or catch_all) and spent no records.

These are people at matching companies, not a company count. country is where the person is. hqCountry is where the company is headquartered.

Run it from an AI agent

Connect the MCP server at https://api.leadocean.io/mcp (OAuth sign-in, no key pasted), then ask in plain words.

Find VPs and Directors of sales at US companies with 51 to 200 employees. Size it first, then show me 25.

The agent counts first with the free tool, then calls leadocean_search_leads with this:

{
  "employeeRange": ["51-200"],
  "jobFunction": ["Sales & Business Development"],
  "jobLevel": ["VP", "Director"],
  "country": ["US"],
  "limit": 25
}

The search costs 1 record per person returned. Use leadocean_search_companies instead when you want companies, not people. It costs 1 record per company.

Run it with the API

One flat JSON body to POST /v1/people/search. Filters are arrays of strings.

curl -X POST "https://api.leadocean.io/v1/people/search" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "employeeRange": ["51-200"],
    "jobFunction": ["Sales & Business Development"],
    "jobLevel": ["VP", "Director"],
    "country": ["US"],
    "limit": 25
  }'

For the free sizing call, put count=true in the URL (not the body) and set limit to 1.

curl -X POST "https://api.leadocean.io/v1/people/search?count=true" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "employeeRange": ["51-200"],
    "jobFunction": ["Sales & Business Development"],
    "jobLevel": ["VP", "Director"],
    "country": ["US"],
    "limit": 1
  }'

data comes back empty and meta.countOnly is true. meta.total stops at 100,000 on the REST API. POST /v1/companies/search takes the same three filters, and the same body returns companies.

Export the list

POST /v1/exports takes the same filters inside a filters object. One export is up to 50,000 rows, and an account can export 500,000 rows a day.

curl -X POST "https://api.leadocean.io/v1/exports" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "sales-leaders-51-200-us",
    "filters": {
      "employeeRange": ["51-200"],
      "jobFunction": ["Sales & Business Development"],
      "jobLevel": ["VP", "Director"],
      "country": ["US"]
    },
    "limit": 5000,
    "preset": "search"
  }'

Poll GET /v1/exports/{id}, then download. Prefer clicking? The Exports page in the app at app.leadocean.io has the filter builder, a column picker, the record price before you start, and a CSV download.

Combine it

• Add jobFunction and jobLevel to reach one buyer at those companies. Sales & Business Development plus VP and Director is the first count above.
• Add industry (for example ["Computer Software"]) or hqCountry (for example ["GB"]) to pick a market. The second count above uses hqCountry.
• Add technologies or technologyCategories to keep companies that run a product. See find companies by technology.

To look up one company's headcount from its domain, use company headcount. To list companies that raised money lately, see find new companies. More ways to build a company list are on the find companies hub.
