Notes and limits
- Employee counts are estimates: modelled headcount from licensed B2B firmographic and technographic data, not payroll or IRS full-time-equivalent counts. Whether FMLA or the ACA employer rules apply depends on the employer's own counts.
- Companies with an estimated 35–65 employees whose headcount grew 15%+ in a year, listed by growth band, then size.
- Growth is shown as a band: +15–20%, +20–50%, +50–100%, +100–200% or 200%+ (estimated). Within a band, companies are listed largest first; the order inside a band is not a growth ranking.
- "200%+ (estimated)" means the growth figure is above 200% and has not been verified; treat it as an estimate.
- Likely branches of larger groups, government bodies, colleges and universities are left out (private schools and non-profits are kept).
- Company-level data only: no personal contacts. Not legal, tax or benefits advice.

FAQ
- Why does 50 employees matter?
- Several US rules start at 50 employees. FMLA covers employers with 50+ employees, and under the ACA, employers with 50+ full-time employees (including equivalents) are "applicable large employers" with coverage and reporting duties. Growing firms near 50 often need HR, payroll, benefits or a PEO.
- Are these exact headcounts?
- No. They are estimates (modelled headcount), not payroll or FTE counts. Use them to prioritise outreach, then confirm with the company.
