Search companies
search_companies[Ids in: none. Ids out: companies[].companyId: company id.] Find companies by BUYING SIGNALS and firmographics — hiring now, fast-growing headcount, revenue band, new leadership, and/or recently funded — optionally scoped by industry, HQ location, and size. FREE (no credits). Returns each company's name, companyId, industry, and size. Combine signals to sharpen: hiring, growingTeamMinPct, revenue and size are ALL required together (e.g. hiring:true + recentFunding:true = hiring AND just raised). LinkedIn can't require recentFunding AND recentLeadershipChange in one search, so asking for both runs each separately and lists companies that have both first — every row then carries signals:[…] and the result says how many have both. The next step is to reach people there: search_people_sales_navigator with companyIds:[the returned companyId values] plus seniorities (and changedJobs / postedOnLinkedIn for timing), or find_decision_makers("") for one company (those pull rows and cost credits). Runs on HeyReagent's shared search database — no account needed. (Note: filtering by which SOFTWARE a company uses is not available on the current data tier.)
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Max companies to return (1–100, default 20). Use 100 to feed the most companies to search_people_sales_navigator via companyIds. | |
| hiring | No | Only companies with open job posts right now (hiring signal). | |
| locations | No | Company HQ locations, e.g. ["United States"]. | |
| headcounts | No | Company size bands. Valid: self-employed, 1-10, 11-50, 51-200, 201-500, 501-1000, 1001-5000, 5001-10000, 10001+. | |
| industries | No | Company industries, e.g. ["Software","Financial Services"]. | |
| recentFunding | No | Only companies with a recent funding event (same as list_funding_signals). | |
| revenueCurrency | No | Currency for the revenue band (default USD). | |
| growingTeamMinPct | No | Minimum headcount-growth percent, e.g. 20 = teams that grew ≥20%. | |
| maxRevenueMillions | No | Maximum annual revenue in millions (same brackets). | |
| minRevenueMillions | No | Minimum annual revenue in millions (e.g. 10 = $10M+). LinkedIn uses fixed brackets (0, 0.2, 1, 2.5, 5, 10, 20, 50, 100, 500, 1000); other values widen to the nearest one. Revenue is LinkedIn's estimate — companies without one are left out. | |
