These are Houston’s 360 largest private companies
The online version of this ranking expands beyond what appears in print; 300+ companies are included in our digital rankings, in addition to the 40 featured in this week’s print edition.
This week’s List is part of a shift in our research methodology and philosophy in 2025, one that will emphasize more data and context for readers while better coordinating the resources available to us and our 44 sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ’s footprint — this year alone.
Information on The List was obtained through Houston Business Journal research or supplied by individual firms through questionnaires that HBJ could not independently verify. In case of ties, firms are ranked by 2023 revenue, then total employees and finally alphabetically if ties remain.
