Nimble is your second brain for managing relationships. This social CRM gives you all the common functionality you'd expect from a customer relationship management system, however they take it a step further by integrating social media services including Facebook, Twitter and LinkedIn.

If you think about how much information is out there on social media nowadays, it seems like it should almost be a mandatory requirement for a CRM. A term they've dubbed as "social listening", will give you context and insight into your relationships.

Test it out and see what you think. It comes with a 14-day free trial. After that, it's $15 per user/month. Since your relationships will either make or break your business, being 'nimble" may be the right solution for you. Normally "document collaboration" and "nimble" are contradictions in terms - see how SavvyDox breaks that contradiction with a new approach to document collaboration.
