I have been using the free version for while and love alot about this tool. Founder is very receptive to ideas and implemented embed tabs within a week of my suggestion. A great feature you do not see often is the 'status/updates feed', a fantastic way to keep team members up to date. I can see this being a way to update clients also, though it needs some more features before it can compete with basecamp/kitchen etc for a client portal (inc. custom domain, white label, better customer notifications etc), but otherwise a great tool, looks lovely and it is easy to pick up and use.
