A Gratipay 'Team' is approximately similar to a Github 'Organization' (which are a special case of a 'User', for many intents and purposes), so we can mimic Github's 'People' box on organization pages as a first step:

But the approximate mapping between Gratipay 'Teams' and Github 'Organizations', also suggests we could pick up some layout from the Github Organization Members page for more detail and a complete listing:

If ever we wanted to allow Gratipay 'Teams' to have subgroups of some sort (such as 'projects', etc., depending on how the terminology shakes out): we could pick up elements of the Github 'Teams' page to list them:

Q: All this suggests to me that perhaps we should rename Gratipay 'Teams' to 'Organizations' (as mentioned in another ticket, I also feel that 'Open Organization' is a better term than 'Open Company', this would unify the terminology even further). Does anyone else concur?

This could overlap with gratipay/inside.gratipay.com#404, because we should have a visualization for holacracy circles and the team page would seem a natural fit.
