Notes and limits
- Ranked by 1-year headcount growth from licensed B2B firmographic and technographic data. Employers with 20–1,000 staff that grew at least +21.8% in a year (the lowest on this list).
- Growth is the exact 1-year headcount change, rounded. Anything of 200% or more is shown only as "200%+ (estimated)" (small teams make such figures unreliable), and inside that group companies are listed largest first.
- Companies are placed by head-office location; metro areas include their suburbs. Schools, universities, government bodies, churches and membership organisations are left out, as are likely branches of larger groups.
- A fast-growing company is not guaranteed to be hiring for your role today; use the careers link to check.
- Company-level data only: no personal contacts.
