For the 2025 ranking, the top 53 architecture firms that responded to the ABJ survey reported more than $425 million in architecture revenue during 2024 for their Austin offices. These same firms employ 465 licensed architects here and provide 1,775 jobs for area workers. Overall the online version of the List features 86 architecture firms, although not all provided local information. These firms, ranked by total employees companywide, appear after the locally ranked firms. Altogether, the 86 firms featured online employ more than 168,003 people across the U.S. and globally. Information on The List was obtained through ABJ research or supplied by individual firms through questionnaires that ABJ could not independently verify. This list uses a tiered rank by Austin office architecture revenue with ties broken by number of licensed architects. Firms that did not respond to ABJ surveys but were still included on this year’s online ranking are sorted by estimated companywide employment figures derived from ABJ archives, annual filings with the U.S. Department of Labor and other firm-specific resources. Inclusion on the List required each firm to have offices in Travis, Williamson, Hays, Bastrop, Caldwell and Burnet counties. This week’s List marks 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 46 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.
