It is an assumption, but one based on evidence:
From the S-1
"We intend to enter into partnership agreements with large cloud services providers, who bundle our application with such providers’ other applications offered to their existing and prospective global customer base in order to drive more data storage and bandwidth utilization fees from such customers. We are currently finalizing contract negotiations with two such cloud services providers for similar partnership relationships."
Regarding SAP, Rory commented in the 23 Aug CEO Nsight video on how an investor found some videos from a large Tier 1 company using nFusz technology and mentioned how these companies did not want NFusz to put out a Press Release with their name in it. Also, divisions of SAP (Health/TV) almost daily post videos to their Twitter page with nFusz interactivity usually found at the end of the videos.
Regarding Salesforce, during Rory's presentation at the 05 Jun LD Micro Conference in Los Angeles a member from the audience asked Rory if he would have to leave Salesforce to use nFusz technology. Rory said he couldn't tell him what was going on, but that he wasn't going to have to leave Salesforce. If you pay close attention you can also see the CFO Jeff Clayborne with a huge smirk on his face when the question was asked. Nfusz also attended Salesforces' Dreamforce last month in San Francisco and posted several pictures with the hashtag #partners
So yes, while this is an assumption I am willing to bet these are the integrations that Rory was referring to as on-going
