The volume of US IT staffing firms represented in SIA’s annual Largest Staffing Firms in the United States report continued to swell in 2018. The report ranks staffing firms by revenue and corresponding market shares. To qualify for the list, firms must have generated at least $100 million in US staffing revenue in 2018.

Of the 157 firms that qualified for inclusion, 47 indicated IT as their largest skill segment supplied, representing 30% of the list. This lagged only industrial, which was the primary segment of 51 staffing firms on the list. Within professional staffing, IT made up nearly half (49%) of the 96 qualifying firms. The next-closest professional staffing segment was healthcare with 29 firms, or 30% of professional staffing firms.

The US IT staffing segment is expected to exhibit its 10th consecutive year of growth in 2019. This consistent growth is reflected in an expanding list of US IT staffing firms making this annual list, as shown in the chart below.

Growth in the US IT temporary staffing segment has generally outpaced overall US temporary help throughout the expansion period. However, the proportion of IT staffing firms represented in our largest staffing firms in the US list has remained essentially constant in recent years at 30% to 31%, as shown below.
