# The 39 largest professional services firms in Nevada

Tamtam tracks 39 professional services firms headquartered in Nevada. This list ranks all of them by number of employees on LinkedIn, led by JT4, Heritage Surveying and BMM Testlabs. Their median headcount is 202. Half of them were founded in 2005 or later. The most common headquarters are Las Vegas (32) and Henderson (4).

This selection of professional services firms in Nevada includes companies primarily based in Las Vegas. Many of them provide IT services and software development, such as Droisys, which delivers tailored technology solutions, and Openxcell, which specializes in web, mobile, AI, and blockchain technologies. Other sectors represented include defense and space manufacturing with JT4, a provider of engineering and technical support to US Air Force, Space Force, and Navy test ranges, and BMM Testlabs, which offers testing, certification, and regulatory compliance services for gaming products.

These companies are primarily mid-sized firms, with employee counts ranging from 343 to over 1,700. A notable trend is the presence of several companies founded in the early 2000s, like JT4 (2001) and Droisys (2003), alongside long-established firms such as JMA, an architecture and planning firm founded in 1945, and TRAX International Corporation, established in 1979.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
