I'm not generally a big fan of new industry acronyms or buzz words. But I have to say I like the term Push Intelligence. It characterizes the value proposition of these type of solutions pretty well.
A leader in this space is Metric Insights. They deliver a platform that starts on the alert end of BI instead of the hunt and search side that many solutions employ. The environment is Key Performance Indicator (KPI) oriented, pushing dashboards and reports to the end user that require attention and skipping the ones that don't. The platform goes a step further in that it offers collaborative features that allow stakeholders to annotate charts to add greater context to the data presented.
Metric Insights is architected to make embedding easy so companies who need sophisticated alerting and collaborative features can add the solution to their BI strategy. The solution is value priced and integrates well with 100's of data sources including Hadoop. MongoDB and Cassandra.
