According to the documentation:
This module is compatible with the following Jive products
• Jive Cloud
- Supports SharePoint 2010 and 2013
• Jive Custom
- Version 5.0.4 and above supports SharePoint 2007 and 2010

but I don't see anything about Sharepoint 365 (online)

Yes, we are actively looking at what it takes to support SP Online and how we can best achieve what we want to do, including starting a POC. Definitely something we want to make happen next year.
SharePoint Online is not yet supported, currently scheduled for first half of next year. We shifted our priorities based on some more urgent customer requests and the usage patterns we were seeing. But this, along with general Office 365 support, is very much an area of focus for us.
