Since this appears to be the basis of the notion that Palantir is a branch of the NSA: the one Palantir person known to have been involved was a 27 year old sales engineer who was subsequently terminated from the company and rehired after the legal investigation Palantir launched on itself for coming within a mile of Aaron Barr cleared him. (This is based on reporting of what happened, not any kind of firsthand knowledge about Palantir, of which I have none).
