If the Hoostsuite software has a interface like a REST Connector or Internal Database, it should be possible to read informations.
Take a look on this page then you can see all methods and connections: http://help.qlik.com/en-US/connectors/Content/Home.htm
I never had worked with a product who wasn´t possible to read informations from Qlik.
Hootsuite can integrate well with Qlik Sense via it's REST API which you find documentation for here:
Integration can be done via both Qlik REST Connector, Qlik WebConnector general and through Qlik Extensions.
