I/O stands for Input - Output, which is a term from computer science. This domain extension is therefore often used by young, tech-savvy companies or, in principle, by start-ups. The advantage is also that terms are often still available here that are already taken as .de or .com.
The .io domain is usually marketed directly via advertising or business cards and is not found so often in Google search results. However, this may also have to do with the fact that it is not yet so widespread.
