Lab41 is a testing facility for big data analytics that is operated by the non-profit funding arm of the CIA called In-Q-Tel. The operation located in the heart of Silicon Valley is unclassified. It was designed to enable private sector software developers and engineers to collaborate on developing techniques to apply analytics to massive amounts of data for the intelligence community. According to Lab41, projects address data visualization, social network analysis and statistical modeling of structured and unstructured information. "Challenge teams" operate out of the Menlo Park, Calif.-based facility, working on selected projects within a three to 12 month time frame.
