Xing (own spelling XING) is a social network in which members primarily manage their professional contacts. Xing is operated by New Work SE in Hamburg. Xing primarily offers a platform for business networks, primarily in German-speaking countries. In January 2021, Xing said it had 19 million users in Germany, Austria and Switzerland. Registered users can enter both professional and private data in a profile. Studies, training and professional career are presented in tabular form similar to the CV. References support the entries. Users can also enter a profile picture, contact details, skills and knowledge, and personal interests. However, there is no obligation to fill out the profile completely with all fields. This information can be used to formulate contact requests as requests and offers. In order to make contact, it is necessary for the contact request to be confirmed by the other party. In any case, the user decides who can see which information (e.g. telephone number, e-mail address or date of birth) from their profile.
