Companies Directory is a data platform that provides access to over 300 million company records sourced from public registers, official databases, and web intelligence. Its primary function is to enable users to search, filter, and export company information for applications such as lead generation, data enrichment, compliance checks, and market research. The tool allows users to narrow results by industry, location, business contact details, social media accounts, and technology stack, then download the resulting lists in CSV, Excel, or JSON formats. Alternatively, users can enrich individual company profiles by submitting a domain name, email address, or social media handle. The platform offers 204 structured data points per record, including legal name, official identifiers, operating status, jurisdiction, firmographics, logos, and contact information. Data provenance is tracked from official registers, providing transparency on the source of each detail. Users can also monitor newly registered companies by subscribing to specific markets defined by city, country, or industry, receiving monthly updates as new businesses appear. The workflow typically involves selecting a target market, applying filters for contact coverage or technology usage, and exporting the list for use in customer relationship management or outreach tools. For users who already possess a list of domains or emails, the enrichment endpoint resolves each entry into a full company profile without requiring manual re-collection. Technical requirements are minimal; the service operates entirely through a web interface and a REST API. The first 100 records are free, and tiered pricing is applied automatically based on the size of the export, with the final price displayed before checkout. Coverage figures are approximate and vary by country and source, and available fields differ depending on the jurisdiction. The platform is designed to serve multiple roles within an organization, supporting sales teams in building targeted lead lists, data teams in filling CRM gaps, and compliance teams in verifying legal identity and registration numbers during onboarding.
