Best way to get information about/from your users?

This year we put out a mandatory survey to collect funding and publication information from our users. This has had some mild success so far, but I am curious how do other organizations get this info?

As a user, depending on the tier of allocation I am requesting on CU Boulder’s Alpine, the form for allocation request asks for the funding information of the project.

There is also an additional checkbox asking if I’d be open to share more about the funding/project, thus I assume that if my usage is above a certain level, they’ll reach out to inquire about my project.
