Highly anecdotal story: a guy I know went to work for Palantir as a sales PM and his TC was in the low GBP 200k. He was a lousy developer with mediocre understanding of technologies but could really smooth talk. I would not be surprised if PLTR is full of people like him.
He's a sales PM though. Is this not exactly what you want? Smooth talking will close deals. Good development doesn't need to happen at the customer site in a sales meeting.
They can't be unprofitable since they are focusing on government agencies that want specific data and government agencies are willing to at least pay cost plus (reasonable) profit.
