Every list of IT staffing companies in USA hiring managers rely on now sits inside a shrinking market. The 57 largest firms earned $27.4 billion in annual revenue in the latest count by Staffing Industry Analysts (SIA), published in June 2026. That was 4.4% less than the year before, and the third year of decline. SIA’s reasons are worth reading slowly if you buy tech talent: offshoring, AI-assisted coding, the end of the post-pandemic hiring bubble and a steady shift from IT staffing to IT solutions. It still expects the market to grow about 1% in both 2026 and 2027.
The firms below are the ones a US hiring manager is most likely to meet, from the biggest technology staffing agency in the country to smaller specialists. For each we say what it actually does, who it suits and what to ask before you sign. We have removed Clutch from the earlier version of this list, because it is a directory of agencies rather than a staffing company itself. First, our own pick for the offshore side of that shift: Zilo AI, for remote IT talent from India working for US teams.

Revenue figures are SIA’s estimates of annual US IT staffing revenue. SIA publishes only the top five in its free summary.
1. Zilo AI
Zilo AI is a staffing and data annotation company based in Bangalore. It hires IT talent for companies in India and abroad on contract, contract-to-hire and permanent terms, and it can build a dedicated team that works only for one client: a remote group of developers, QA engineers, data engineers or cloud specialists who work as an extension of the in-house team. It does not have US offices, and we would rather you knew that before you call.
Zilo also runs data annotation, data collection, transcription, RLHF and AI evaluation work for AI teams. Zilo says it has over 1,600 trained annotation and ASR experts, has annotated more than 10 million data points for industries from retail to BFSI to healthcare, and works in about 26 languages.
Best for: US companies that want to add offshore engineers without setting up their own entity in India. See Zilo AI’s IT hiring services.
What to check: overlap hours with your US time zone, how code and data access will be secured, and who manages the team day to day.
2. TEKsystems
TEKsystems, part of Allegis Group, is the largest IT staffing firm in the US, with $3.92 billion in IT staffing revenue in SIA’s 2026 ranking.

Best for: companies that need several IT contractors quickly, across help desk, infrastructure and development roles.
What to check: how candidates are screened technically before you see them.
4. Kforce
Kforce traces its roots to 1962, when two IBM salesmen started a search firm after noticing that the first thing computer buyers asked for was someone to run the machine. Today it describes itself as a solutions firm specializing in technology, finance and accounting, and professional staffing. It moved from sixth to third place in SIA’s IT ranking this year, with $1.22 billion in IT staffing revenue.
Best for: mid-sized and large companies hiring developers, data and ERP specialists, and finance systems staff.

5. Experis
Experis is ManpowerGroup’s IT brand and the fourth-largest IT staffing firm in SIA’s ranking, at $1.21 billion. Alongside IT staffing it sells consulting in cloud, AI, data and applications, so it suits buyers who may want to move from staff augmentation to a managed project later.
Best for: companies already using ManpowerGroup for general staffing who want IT on the same contract.
What to check: which parts of your work would be staffed and which delivered as a service, since pricing and liability differ.
6. Everforth Apex (Apex Systems)
Apex Systems now trades as Everforth Apex, part of the commercial segment of Everforth, the company formerly called ASGN, which is headquartered in Glen Allen, Virginia.

Apex runs offices across the US and sells AI and data project work alongside IT staffing.

It says it has more than 75 years of specialized staffing experience.
Best for: small and mid-sized companies hiring one or two tech roles, or converting a contractor to full-time.
What to check: conversion fees if you plan to hire a contractor permanently.
8. Randstad
Randstad places permanent and contract technology professionals in application development, infrastructure, functional IT, and data and analytics. Its digital specialties cover cloud and infrastructure, customer experience, data and analytics, and digital and product engineering, and it also handles work visas for contract talent recruited from abroad.
Best for: enterprises that want IT staffing from the same supplier as their high-volume or professional hiring.
What to check: whether your roles sit with Randstad’s digital team or its general staffing branches.
9. Beacon Hill Technologies

It provides technology staffing, consulting and workforce solutions in cloud, cybersecurity, data and software development, on staff augmentation, contract-to-hire and direct hire terms, through offices across the US.

What to check: coverage in your region if you are far from the firm’s main offices.
How to choose an IT staffing company
Start with the shape of the need. A single specialist for six months, a team of twenty contractors for a migration and a permanent engineering hire are three different purchases, and each of the firms above is strongest at one of them.
- Large contractor programs: TEKsystems, Insight Global or Experis.
- Contractors who may become a project: Everforth Apex, Kforce or The Judge Group.
- One or two hires at a smaller company: Robert Half, Beacon Hill Technologies or Motion Recruitment.
- Offshore engineers working as a dedicated remote team: Zilo AI.
Ask every shortlisted firm for its bill rate or markup in writing, its time to submit and time to fill on roles like yours, and its replacement terms. If your hiring is mainly for machine learning and generative AI roles, see our separate guide to AI staffing agencies. To talk about a remote team from India, contact Zilo AI.
Frequently asked questions
What is IT staffing?
IT staffing is the supply of technology professionals, such as developers, engineers, analysts and support staff, to a company on a contract, contract-to-hire or permanent basis. The staffing company recruits and screens the candidates, and for contract roles usually employs them and bills the client an hourly rate.
What is the largest IT staffing company in the USA?
TEKsystems, part of Allegis Group, with $3.92 billion in IT staffing revenue in SIA’s 2026 ranking, ahead of Insight Global at $3.28 billion.
How much do IT staffing companies charge?
Contract staff are billed hourly, with the agency’s markup added on top of the worker’s pay, and permanent placements usually carry a one-time fee linked to first-year salary. Rates depend on the role, location and volume, so compare written quotes.
What is the difference between IT staffing and IT consulting?
In IT staffing you direct the work and the agency supplies people. In IT consulting or managed services, the provider owns the outcome and manages its own team. Several firms on this list, including TEKsystems, Experis and Everforth Apex, sell both.
Can a US company hire offshore IT talent through a staffing company?
Yes. Offshore staffing firms such as Zilo AI recruit and employ engineers in India who work for a US client remotely, often as a dedicated team. Plan for time zone overlap and data security from the start.
