Due to the nature of Palantir’s work with government agencies and law enforcement, the data analytics startup is one of the most-secretive companies in Silicon Valley, but we do know that it’s extremely popular with investors. According to an SEC filing on Wednesday, the startup has raised $880 million in new funding, which brings its total lifetime funding to $2.32 billion, and gives it a valuation of $20.33 billion. This puts it up there with Uber, Xiaomi, Airbnb, and Snapchat as one of the five most-valuable startups in the world. As I said before, most of the company’s inner workings are a secret, but we do know from leaks and piecing together bits of information that it does data analysis for numerous government organizations, including the CIA, FBI, and the Marine Corps.
