Zaheer from Levels.fyi here. Note that companies struggle with data as well. There's dozens of companies that solely exist to provide better data to companies around salaries (Radford, OptionImpact, etc.). All of these have limitations as well (title matching, recency of data, etc.) and generally companies subscribe to multiple providers to get a better picture of what the market pays. Companies in fact purchase data from us as well (the same data you see on site but formatted in a way that's easier for comp analysts to use). The reality is that there is tons of nuance that goes into pricing a job / candidate effectively. Each candidate has unique skills even if two candidates have the same title, level, etc. That's why it's almost never a fixed number and often a range.
