Casa dos Dados operates as a comprehensive search engine for public data on Brazilian companies, aggregating information from official government sources like the Federal Revenue. The platform allows users to search for businesses by their official registration number (CNPJ), company name, economic activity, and location, providing detailed profiles that include addresses, partners, and share capital. Its primary users are likely other businesses engaged in B2B sales, marketing intelligence, and due diligence. While the service makes publicly available information more accessible, this concentration of data can be leveraged for malicious purposes. For instance, the easy access to partners' names and business details could facilitate targeted phishing campaigns, fraud, or other scams directed at company officials. Business owners should be aware that their public registration data is aggregated on such platforms and exercise caution regarding unsolicited contact or requests for sensitive information.
