Have you heard about HubSpot's CRM? It really is free and it really is awesome.
I'm running across more and more prospects every day who are using large, costly CRM's like Microsoft Dynamics and Salesforce. And while these are certainly good products, they are just too robust for most of the companies I deal with.
Here's a quick description of HubSpot's CRM from Business News Daily:
A popular inbound marketing and sales platform, Hubspot's CRM software streamlines your sales process across multiple channels in your organization. It works in the background to save you from wasting time manually performing repetitive sales and marketing tasks. The software also specializes in automatically logging and syncing data from different sources of communication, such as your website, phone calls, emails, social media and more.
