Bloomberg published an exposé on Thursday that in part reported on how data firm Palantir effectively used JPMorgan as a testing ground to develop a surveillance analytics tool for the financial sector. The tool reportedly reviewed private information, like GPS locations and browser histories, to keep tabs on the bank’s employees. Billionaire venture capitalist Peter Thiel founded Palantir in 2004, along with current CEO Alexander Karp, to develop programs that could analyze data gathered by the Pentagon and CIA in Iraq and Afghanistan.
