Before diving into the 10 giants leading the IT staffing ecosystem, it‘s helpful to understand exactly why this sector has swelled into a $200+ billion global industry.
What does an IT staffing firm do exactly?
IT staffing firms serve the crucial role of identifying, vetting, upskilling, and deploying technical talent into client organizations on a temporary or permanent basis. Models include:
- Contract staffing: IT pros work on client projects on a time-bound contract basis, then return to the staffing firm for redeployment
- Contract-to-hire: After an initial contract period, clients can elect to permanently hire standout contract talent
- Direct hire recruitment: Firms source and screen candidates for direct full-time hiring
Why the surging demand?
As enterprises have grown more reliant on software, analytics, cloud platforms, and customer-facing digital systems, demand has spiked for developers, architects, technicians, and other specialists who can build and operate technology infrastructure.
However, recruiting niche technical skillsets remains notoriously challenging. Employers also prefer workflow flexibility given economic uncertainties.
Enter IT staffing specialists, who maintain extensive candidate networks, industry connections, and recruitment expertise. They can rapidly deliver talent at scale to client organizations on flexible terms.
