Retrieve company signals for business events and growth

Company signals give you visibility into what is happening inside your target accounts - funding rounds, surges in hiring, headcount changes, shifts in IT spending, and news events across seven categories. You can retrieve signals for companies you already track by Lusha ID, or search by company name or domain if you don’t have IDs stored. Both endpoints support up to 100 companies per request.

Each signal type you include in a request counts toward your credit usage. Request only the types you need.

Sub-filters

You can narrow results within certain signal types using the filters.include object:

Sub-filter	Applies to	Behavior
`newsEventTypes`	All news signals	Returns only matching event types (OR logic)
`hiringByDepartments`	`surgeInHiringByDepartment`	Returns only matching departments (OR logic)
`hiringByLocations`	`surgeInHiringByLocation`	Returns only matching country/state combinations (OR logic)

When filtering by hiringByLocations, you must always include country. Providing state without country returns an HTTP 400 error. Filter values are not case-sensitive.

Example: filter by location and news event type

{
  "companyIds": [3416],
  "signals": ["surgeInHiringByLocation", "financialEventsNews"],
  "startDate": "2025-01-01",
  "filters": {
    "include": {
      "hiringByLocations": [
        { "country": "United States", "state": "California" },
        { "country": "Germany" }
      ],
      "newsEventTypes": ["Funding Round", "IPO"]
