Checked — none published
Checked 2026-08-27 and no citable figure found. Four sweeps were run and all came back empty for this company: (1) its own /about, /about-us, /company, /careers, /jobs and /team pages, pattern-matched for a self-published headcount; (2) stockanalysis.com's private-company page, which footnotes each figure to its source; (3) its Forbes company profile, which states a headcount and the month it is as of; (4) a targeted web search. Everything the search returned was a LinkedIn-scraping aggregator, and those disagree with each other by wide margins and cite nothing, so they are not used here. The field is null rather than carrying the round guess it held before.
