Qichamao (Enterprise Query Treasure) is a Chinese business-information platform focused on helping users research companies and assess their commercial credibility. It provides searchable company registration and credit records, including shareholders, legal representatives, business details, overseas investments, court judgments, trademarks, patents, and contact information. Users can also look up business owners, search by industry or tax number, and explore visual maps of connections among companies, people, and investments.

The platform serves both individual researchers and organisations seeking structured data. Its services include advanced and bulk company searches, brand and intellectual-property lookup, business-change tracking, and risk checks covering court announcements, judgments, dishonest entities, and enforcement records. Qichamao also offers customised datasets drawn from more than 230 million companies, business leads, and a data marketplace selling company records filtered by region, industry, and year. Additional features include enterprise profiles, industry and regional reports, company rankings, supplier recommendations, and a mobile app. These tools help users investigate counterparties, identify potential customers, monitor corporate developments, and understand business relationships using broad, regularly updated enterprise information.
