Once upon a time, Dropbox was a place to store your files on the cloud.  Now, users are demanding much more collaboration with their files and their teams, so Dropbox has been evolving to meet those needs. Much like other technology companies in Silicon Valley, Dropbox has taken note of the opportunity for growth that the construction industry offers due to general unwillingness to adopt new technologies in the past. The company recently announced that they are forming partnerships with several construction technology companies like PlanGrid and Aconex.
