Company Data

Every company the Signal API returns carries one consistent profile. The same profile appears on company enrich, company search, contact enrich (the contact's employer), and on any signal that is about a company.

This page lists every company field we hold, in two tables:

• Standard fields: returned by the API today.
• Available on request: phone, street address, SIC and NAICS codes, website-derived business profiles, technology stack and IP-to-company, added for you under a data agreement.

Coverage

Domains are normalized before lookup. Alias domains (redirects, regional sites) resolve to the primary domain and return the same id.

Standard fields

These fields come back in every API response that includes the company. No extra setup.

Fill is the share of the 18.0M profiled companies that have a value (October 2026). When we have no value, the API leaves the key out. Treat a missing key as unknown.

Coverage by region, industry and size

Counts across the 18.0M profiled companies (October 2026). Region and country come from hq_country, industry from industries, size from employee_count_low and employee_count_high.

By region

Top 15 countries

By industry group

The 363 industry labels roll up into 20 LinkedIn industry groups.

By employee count

Available on request

We can add any of these fields to your API responses, or deliver them as a monthly flat file to your GCS bucket, under a data agreement. Send the fields and record volume to [email protected]. We send back a sample with your own records matched.

Fill is the share of the source dataset that has a value (October 2026):

• US: our US firmographic dataset (12.9M companies).
• Web: our website-derived company profiles (5.1M companies, global, 41% US, refreshed monthly).

Where the company object appears

Example

POST /v1/companies/enrich with {"domain": "hubspot.com"} returns:

{
  "company": {
    "id": "3365d9b9-da6a-4627-8f1b-2a9e97a690a6",
    "name": "HubSpot",
    "domain": "hubspot.com",
    "linkedin_url": "linkedin.com/company/hubspot",
    "description": "HubSpot builds a customer platform for marketing, sales and service teams.",
    "founded_year": 2006,
    "industries": [
      "Software Development"
    ],
    "industry_confidence": 1,
    "b2b": true,
    "b2c": false,
    "employee_count_low": 5001,
    "employee_count_high": 10000,
    "employees_on_linkedin": 12262,
    "employee_count_confidence": "linkedin",
    "revenue": "500 Million to 1 Billion",
    "revenue_confidence": "derived_from_headcount",
    "hq_city": "Cambridge",
    "hq_state": "Massachusetts",
    "hq_country": "US"
  }
}

The full response also carries the signals array and a signal_summary count by signal type.

Values

Revenue bands (10, smallest to largest):

• Under 1 Million
• 1 Million to 5 Million
• 5 Million to 10 Million
• 10 Million to 25 Million
• 25 Million to 50 Million
• 50 Million to 100 Million
• 100 Million to 250 Million
• 250 Million to 500 Million
• 500 Million to 1 Billion
• 1 Billion and Over

Employee count. Company and contact search take integer employee_count_min and employee_count_max. Buyer-intent endpoints take these bands:

• 1 to 10
• 11 to 25
• 26 to 50
• 51 to 100
• 101 to 250
• 251 to 500
• 501 to 1000
• 1001 to 5000
• 5001 to 10000
• 10000+

Industry (363 labels). Filters use a case-insensitive substring match: "Software" matches "Software Development". GET /v1/filters returns the full list for free.

Migrating from the flat-file schema

Earlier versions of this page described a 17-field US flat file keyed on cc_id, with lettered size and revenue codes (A-L). The API now keys every company on id and returns integer headcount bounds and named revenue bands. The flat-file fields (phone, street address, SIC, NAICS) are still available on request.
