"The company, based in Palo Alto, California, is essentially a hybrid software and consulting firm, placing what it calls “forward deployed engineers” on-site at client offices."
This says everything about Palantir, and depending on your perspective, their valuation is (not) justified.
It's justified if you think of the equation Palantir = McKinsey + IBM. On the other hand, no consulting firm should have 20x revenue multiple.
