A Reddit post featured in the image claims a company’s Palantir Foundry rollout took 15 months instead of the originally estimated 4 months and required extra contractors.
The author says Palantir sales engineers sold a “10x savings” story, but the project became more expensive through additional contracts, outside agencies, and slow delivery.
The criticism centers on Palantir FDEs and engineers allegedly shipping hardcoded, brittle logic, while the company delivered 0 ROI to date and the CEO blamed the internal IT team for delays.
Reply comments echo the complaint, describing FDEs as essentially sales engineers who can increase billable hours and leave customers with hard-to-maintain implementations.
