Private Company Search API - find and enrich private companies

Private Company Search API turns a private-company intelligence dataset into a clean, structured export. Search private companies by what they do, how big they are, where they are based, how much they make and who owns them, then export the matches as JSON, CSV or Excel.

Bring your own API key and pay only for the records you keep.

Why use this actor?

• Private-company focus - built for private and hard-to-find companies, not just public filings.
• Rich firmographic filters - keywords, employee size, headquarters location, revenue, founded year, business model, ownership and end customer, all as proper fields.
• Search or enrich - discover companies by criteria, or enrich specific companies you already know by domain or company id.
• Advanced escape hatch - pass any provider filter the fields do not surface through a single raw JSON object.
• Pay per result - you are charged only for the records actually returned, up to 5,000 per run.
• No proxies, no blocks - data comes through a stable API, so runs are fast and reliable.

Use cases

• Deal sourcing - build lists of private acquisition or investment targets by size, geography and model.
• Market mapping - map every company in a niche defined by keywords and business model.
• Lead and account research - find lookalike companies and enrich them with firmographics.
• CRM enrichment - append industry, employee size, revenue, ownership and funding to your records.
• Competitive intelligence - track private competitors that public databases miss.

Input

Configure everything from the visual editor. Every filter is a proper field, no code needed.

Search by criteria:

{
  "searchMode": "search",
  "keywords": "industrial automation, robotics",
  "employeesMin": 50,
  "employeesMax": 1000,
  "hqCountry": "United States",
  "revenueMin": 10000000,
  "ownership": "bootstrapped",
  "endCustomer": "b2b",
  "maxResults": 100,
  "apiKey": "YOUR_API_KEY"
}

Enrich known companies by domain or company id:

{
  "searchMode": "enrich",
  "domain": "acme.com, example.io",
  "maxResults": 50,
  "apiKey": "YOUR_API_KEY"
}

Advanced raw filters

Some provider filters are not surfaced as fields. Pass them through rawFilters, a JSON object merged verbatim over the built request body (raw values win) and sent straight to the search endpoint:

{
  "searchMode": "search",
  "keywords": "logistics",
  "rawFilters": {
    "employees_range": [200, 5000],
    "any_custom_provider_field": "value"
  },
  "maxResults": 100,
  "apiKey": "YOUR_API_KEY"
}

The actor sends your filters straight to the search endpoint, so rawFilters is the reliable way to use the full filter surface of your plan.

Output

One clean JSON object per company, with the useful firmographics lifted to stable top-level fields and the full raw record preserved:

{
  "company_uid": "abc123",
  "name": "Acme Robotics",
  "domain": "acme.com",
  "industry": "Industrial Automation",
  "naics": "333249",
  "employees": 420,
  "revenue": 85000000,
  "year_founded": 2011,
  "headquarters": "Austin, Texas, United States",
  "ownership": "bootstrapped",
  "funding": null,
  "end_customer": "b2b",
  "business_models": ["hardware", "saas"],
  "description": "Builds robotic automation systems for warehouses.",
  "profile_url": "https://example.com/companies/acme"
}

FAQ

What is the Private Company Search API?

It is a private-company intelligence API. It lets you search private companies by keywords, size, location, revenue, founded year, business model, ownership and end customer, and enrich specific companies by domain or company id. This actor runs that search and exports the matches as JSON, CSV or Excel.

Do I need an API key?

Yes. This actor calls a private-company data API on your behalf using your own key (bring your own key). The underlying provider is Grata, and access is typically enterprise-provisioned rather than fully self-serve. Get a key from the provider, paste it into the input, and run. Your key is stored securely and never logged. You can also set it as the DATA_API_KEY environment secret instead of putting it in the input.

What is the difference between search and enrich?

Search discovers companies matching a set of criteria and pages through all the matches automatically. Enrich looks up specific companies you already know, by domain or by company id, and returns one record each.

What filters can I use?

Keywords and exclude-keywords, employee range, headquarters country, state and city, revenue range, founded-year range, business models, ownership and end customer. Anything not surfaced as a field can be passed through the advanced rawFilters JSON object, which is merged over the request body and sent straight to the search endpoint.

How many results can I get per run?

Up to 5,000 records per run. Search pages automatically until it reaches your Maximum results cap or the results run out. For larger sets, split the search by geography, size or keyword across multiple runs.

How much does it cost?

Pricing is pay-per-result: a small fixed amount per company record returned, plus standard Apify platform usage, plus your own API usage against your key. A run that returns nothing costs almost nothing. Set Maximum results to cap each run's spend exactly.

Can I run this on a schedule?

Yes. Use Apify Schedules to run it daily or weekly and connect the dataset to Zapier, Make, n8n, webhooks or the API to push new companies into your CRM, deal-sourcing pipeline or data warehouse.
