Google has released Springboard, an app that allows Apps for Work users a way to search across all the different, compatible, Google Apps services. The application is invite only, but the early reviews give Apps for Work users a glimmer of hope.
Google has announced Springboard. It's a search tool for enterprise that lets you search all your documents, contacts and emails in one place. Beyond that, Google may build in smart assistant tools in the future, so it would be somewhat like Google Now for Work.
