Signalbase — COMPANY search independent of any signal: profiles with industry, headcount, location, founded year, categories. Filters: `search` (free text), `domain`/`linkedin_url` (exact lookup), `industry`/`categories` (comma-separated), `countries`, `employee_count_min`/`max`, `founded_year_min`/`max`. `limit` ≤100 — flat price per call. Use to resolve/browse companies before pulling their signals.
