CNPJ Aberto is a Brazilian business research platform that organizes public company information to support professional decisions. It provides free searches for companies by CNPJ, business name, trade name, or partner, with access to registration details, economic activities (CNAE), registration status, addresses, and corporate relationships. The platform’s data comes from official Brazilian government sources, including Receita Federal records, and is updated monthly.

For deeper research, its Pro subscription brings together tools for compliance, sales prospecting, due diligence, and portfolio management. Users can create company dossiers, explore corporate networks and change histories, check public sanctions and active debt records, monitor companies, and find leads using filters such as activity, location, and size. Pro also supports batch searches, PDF reports, CSV exports, and integration through a REST API. A natural-language search feature helps users identify companies matching a desired profile.

Designed for professionals and teams, CNPJ Aberto serves users such as lawyers, accountants, credit analysts, journalists, developers, and entrepreneurs.
