• SalesforceIQ for Sales Cloud - A chrome extension and mobile apps that link to Salesforce. Like Salesforce's version of Cirrus Insight. 
• SalesforceIQ app - a stand alone CRM app. 

It was formerly RelateIQ and was purchased by Salesforce. 

See the SalesforceIQ Keynote from Dreamforce '15 and the Press Release.

• The Keynote was the typical mix of playacting, props and videos but toned down quite a lot from the other keynotes, which was refreshing. 
• They had some good video stories in there. 
• Overall I found the keynote to be a good balance of information and showmanship. 

Notes

• Try googling for SalesforceIQ - it's hard - Google tries to be smart and drop the IQ bit. Try "SalesforceIQ" then the query you want.  
• I can't find any info for SalesforceIQ in the Partner Portal
• There are no SalesforceIQ groups in the Success Community that I can find. There is a group now! Here is the link.
