Highrise vs WordPress: What are the differences?

Highrise: Simple CRM by 37signals. Highrise CRM helps you manage your contacts, keep track of who said what when, schedule follow-ups, set reminders, and convert leads into done deals; WordPress: A semantic personal publishing platform with a focus on aesthetics, web standards, and usability. The core software is built by hundreds of community volunteers, and when you’re ready for more there are thousands of plugins and themes available to transform your site into almost anything you can imagine. Over 60 million people have chosen WordPress to power the place on the web they call “home” — we’d love you to join the family.

Highrise belongs to "CRM" category of the tech stack, while WordPress can be primarily classified under "Self-Hosted Blogging / CMS".

Some of the features offered by Highrise are:

• A person’s history on one page- Every contact in Highrise gets a page. You and your co-workers can add notes from calls, conversations, meetings, or any other historic information about this person.
• Add tasks and get things done- Tasks help you get things done. Assign tasks to yourself or to others. Add action categories (Call, Thank You, Demo, Fax, Email) for quick scanning. Check’em off when they're done. Highrise will even send reminders to your email account or mobile phone!
• Track deals, proposals, and leads- Know which proposals/bids are pending, which you’ve won, and which you’ve lost. Enter notes about the deals, attach proposals or contracts to the deals, and keep a log of any changes.

On the other hand, WordPress provides the following key features:

• Flexibility
• Publishing Tools
• User Management

"It works the way i do... from email" is the primary reason why developers consider Highrise over the competitors, whereas "Customizable" was stated as the key factor in picking WordPress.
