Methodology
Source: licensed B2B firmographic and technographic data, pulled 9 Oct 2026; page updated 2026-10-09. Scope: companies headquartered in the city with 10–500 employees and at least 10 data profiles; the top 50 by 1-year headcount growth per industry, after removing likely local branches of foreign or 1,000+ staff groups; companies with zero or negative growth are left out. Growth is the modelled change in the company's own employee count over the last 12 months; values above 200% are labelled estimated because they come from small headcounts. Location is the company's headquarters city; firms headquartered elsewhere with large local offices are not included, and likely local branches of foreign or 1,000+ staff groups were removed by a name/website rule that can miss some branches. Some companies are local branches of larger groups; the size band is for the local entity. Figures move between monthly editions. Company-level data only: no personal names, emails or phone numbers.
We publish a ranking only when at least 15 companies qualify, and skip a page when its top 10 would repeat another page.
