How we calculate this
Roughly a quarter of AI-startup postings disclose pay. We extract the USD range from those that do, normalize each to a midpoint, and aggregate across distinct postings (deduplicated by posting ID). The minimum, median, and maximum above are based on 149 disclosed salaries. We publish aggregate ranges only, never a single company's salary, so the numbers stay representative rather than anecdotal.
