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 131 disclosed salaries. We publish aggregate ranges only — never a single company's salary — so the numbers stay representative rather than anecdotal.
