By Diana Asbury

Cisco Spark is a bit different from Slack in that, while Slack focuses mostly on messaging, Cisco Spark has the bigger picture in mind and focuses on collaboration as a whole.

Pricing: Free plan, Plus plan for $12/user/month

24. Salesforce Chatter

salesforce chatter

Chatter is Salesforce’s communications hub, connected to their CRM. It’s easy to post company news, and see replies and responses in a more organized way than Slack. There are also dedicated groups, like Slack “channels” to connect employees across an organization or in a certain topic.

The interface feels similar to LinkedIn or Facebook with an activity feed down the middle of the page, and various links on the side.

Simpplr also has profiles and areas of expertise for each employee so you know who to go with any questions. It’s also great for getting the pulse of the company on certain issues in a non-threatening and easier way than email, for example. Simpplr is also built on the Salesforce platform.
