Ranked entries are ordered by the most recent publicly available employee count for each organization; entries marked "est." come from a third-party estimate rather than a self-reported figure. Organizations without a public headcount are listed alphabetically below the ranking rather than guessed.
This directory is checked and reordered on a regular basis as new employment figures become publicly available.
Data checked September 10, 2026. The Guide reviews and reorders this list on a regular basis.
