thanks for your question!
We're a SaaS (Software-as-a-Service) company, so (in a manner of speaking) our solutions are "Cloud" solutions, too. (edit: Actually, we've been doing this for the last 13 years now, before someone coined the terms "SaaS" or "Cloud"). No need for an on-premise installation.
Brennan Kirby could arrange for a live (screensharing) demo of our solutions in a real Jive Cloud instance, if you're interested.
You say there is "no need for an on-premise installation." Is it possible to install on premise? Specifically curious about TemboSocial Polls & Surveys, but interested for other products as well.
