The seat holder is identified in Unify's professional profile dataset, then confirmed against the company's published leadership page, its SEC filings, and Wikipedia before publication. Career and education rows carry the public document they were taken from.

Company figures are read from the Unify headcount page for the same company and are profile coverage measures, never company-reported workforce totals. The employee preview lists vice president and senior vice president level profiles by department. No personal contact details are published.
