Dropbox is acquiring a data visualization startup called Parastructure, according to TechCrunch. It's one of those deals where nobody is talking yet, but what little info is publicly available about Parastructure helps shed some light on it. It's hard to imagine Dropbox getting into the analytics software business that Parastructure was targeting, but it's not hard to imagine Dropbox acquiring some talent that can help it scale onto, and query, new data technologies. And, like Box did with its dLoop acquisition, Dropbox might also be looking to improve search functionality for business users.
