We have also been using Phabricator for the last year in the FinTech startup were I direct the technical team. Phabricator is really awesome in general and has been a live saver.<p>We started using it due to the Arcanist pre-commit hooks. We now use it for issue tracking and may be soon migrating our &quot;scrum&quot; functionality from JIRA to Ph.<p>The only downside I see is that it is not very well documented... in fact I will say it is all the opposite. But still, the fact that we use it happily shows how good it is!
