HR consultants advising on compliance, policy development, HR strategy, and organizational transformation.

- Verticals
Overview
HR Consulting & Advisory firms advise employers on HR strategy, compliance, policy development, and organizational transformation. The market runs from the global human-capital consultancies (Mercer, WTW, Aon, Korn Ferry) down to a deep base of regional and boutique HR advisors, and the same NAICS category absorbs much of the compensation, DEI, and org-design work tracked separately here.
Revenue blends retainer relationships with project engagements, and demand has grown steadily with the rising regulatory and talent-management complexity employers face. Margins are healthy and capital needs minimal, since it is a people-and-expertise business.

This is the catch-all professional-HR code: 541612 sweeps in most compensation, DEI, and org-design consulting too, so the $24.6B is the whole HR-advisory field rather than pure strategy work. The neighboring segments in this sector are subsets of it, not additions to it. Firms average 20 employees, twice the sector norm, because the human-capital majors (Mercer, WTW, Aon) sit inside this code alongside the boutique base.
