For a contact insights (management) centric organization this is a winner all day long. If you have very dynamic reporting or forecasting needs this is not a CRM for you. This tool is great if you are just starting (alternative to ACT!, Goldmine, Outlook CRM Manager). In fact, it's awesome for providing insights in the social area which can even add to CRM tools like Salesforce.com, Sugar, or SalesLogix CRM which are lacking in this area. And, with API's can be integrated into the tool, it's great for real estate, financial service, or other professional contact driven sales relationships. It is also excellent for Fundraising Development Officers hoping to gain insights into their Donors! So, B to C is super. And, B to B may need a little more power if they are more sophisticated and mature with CRM.
I suggest asking the following questions to discern if this is right for you. Are you B to C or B to B? Do you work with Accounts or Contacts? What are your forecasting requirements? Are you a public company or private? Have you used another CRM before? Do I (or my team) add a lot of new records into a system daily?
In summary, this is a simple Social Intelligence platform tool for a small business development team which is inputting new data to use in their business. In addition, a superior tool for a nonprofit membership director or nonprofit development officer who need to supplant the data provided in their existing donor or membership management system. For most, Nimble is not a replacement for an enterprise wide CRM system but rather would add value to an existing CRM, Donor Management, or Membership Management System.
