Clinchpad
Clinchpad is a CRM application that is a lot simpler to use compared to traditional CRM platforms, yet far more powerful and versatile than spreadsheets. It was built with simplicity in mind, giving users a dashboard that presents the most important information they need as they go through the work day, without any clutter. You can use it to manage contacts of all types (leads, prospects, customers, organizations, etc.), see how every deal is doing in the sales pipeline, as well as organize your prospects by products, region and source. Clinchpad supports integration with many other online services and business tools, like GMail, Zapier, Mailchimp, Box, Google Drive, Google Calendar, Dropbox, Skydrive, Jotform, Unbounce and plenty of others. Small businesses can get started with this CRM application right away, as there's a free version that supports up to 100 leads and 250 MB of storage space. As your business grows, you can upgrade to one of the more advanced editions.
