How do you track company properties in Mixpanel?

We're building a SaaS product and we want to track all the typical behavioral stuff about our users. We're using Mixpanel atm, and I've figured out how to send events, how to tie them to users, how to attach properties to the users, etc. But I seem to be missing one more essential concept: "an account". What should I attach these "meta" properties like account size, billing plan, industry, etc to? I can replicate this data on each user, but then I'll need to send updates with every event, some information can become stale, etc.

Does anybody know if Mixpanel even supports the concept of "accounts" or "companies"? Does any other similar tool support it?

Thanks, IH!
