Hearken, Groundsource, and the LenFest Institute grant - does BLOX integrate?

Does anyone have any experience integrating Hearken or Groundsource with BLOX?

You may have heard, but in case you haven't, The Lenfest Institute for Journalism is offering a 650k grant to help newsrooms deepen engagement with audiences using either of these tools.We are considering going for the grant, but I am having a hell of a time getting anyone from TN / Blox to tell me if the tools will work inside our system. 

Any experience or confirmation from the mother ship?
