We've been using Koan at AskNicely for six months for the leadership team to track weekly progress against strategic priorities and now all our teams use it too.
We're big believers in fast feedback and the slack integration keeps everyone up to date but the real benefit is alignment, better strategy discussions and faster execution.
+1 on responsiveness of the Koan team. I love how this product is built by people that have successfully scaled startups and really understand the value/challenge of keeping teams focused.
