At my current firm we use Trello for managing projects: we use different boards for different clients and then manage tasks, client info, etc. with lists inside these boards. However, as we grow and gain more clients we've began to find this a bit unmanageable (esp. trying to find to-dos buried inside each board).
At the moment we're open to trying something new, or else rethinking and streamlining.
Just wondering, what project management tool do you use, and how do you find it?
