Qichamao and Tianyancha are websites for querying company registered industrial and commercial information, trademarks and patents, business conditions, investment information, equity composition, shareholders, etc. The content that can be queried for free is limited, and most of them are still required You have to pay to view it. After all, some content is cooperated with the government.
The specific difference is actually not big. If you don’t use it often and check it occasionally, there is no big difference. If you check it frequently, you should pay attention to the update speed and real-time nature of the information.
Tianyancha’s advertising is good, so it currently has the most users. Qichamao, Qixinbao, and Qichacha are all in the address echelon. You can try them all.
Finally, based on personal experience and feedback from netizens, I recommend the company Chacha. The information is updated relatively quickly.
