I'll vouch for Campfire also. It's relatively easy to hook notifications into it so that commits, test failures, and bug reports show up. In my last two companies we've ended up with then dynamic of "if it doesn't notify campfire, it didn't happen." I use Highrise also for CRM. If it's just one or two of you then it's probably the only CRM out there that's simple enough to get into your workflow. If you're managing a salesforce then you probably want something different. But for just remembering who my clients are and when I need to contact them, it's amazing.
