Well, yes, a new web service has just appeared, and it is not the only one, that allows companies to create and manage their corporate page aimed at receiving feedback and interacting with their customers. The service in question is called Ideaffect and it has three types of payment rates, with different configurations, allowing its use as a trial for 30 days.
Ideaffect gives the possibility to companies, under a subdomain or through an alias of the domain of these, that these have a web space for interaction with customers, with different internal tools for this purpose that allow them to configure general aspects to personalize the structure of the website, also having a customizable widget to include in their corporate pages.
And it is only waiting for the interaction with the clients who contribute their ideas, and about them, their comments and votes, being the administrators and moderators establishing the status of each of the proposals with their corresponding official messages if appropriate. Who knows Uservoice, at this point very evolved, has to know that Ideaffect in general lines it goes with that same philosophy.
