Company description
HireArt's mission is to make it easy for companies to build and manage a world-class contract workforce.
Today, mid-sized companies with contract workforces must navigate significant legal, financial, talent acquisition, and operational complexities to build and manage these workforces on a global scale. In most cases, they rely on a stack of point solutions: agencies to source and employ talent, a software system to track workers and agencies (VMS), and a service to provide day-to-day management of the program (MSP). The default contract workforce stack doesn’t provide much visibility into or control over the workforce, because the pieces of the stack don’t integrate well together, resulting in massive administrative headaches and frustration for companies.
HireArt’s delightful intersection of humans and software provide all of the tooling needed for mid-sized companies to hire contractors anywhere in the world compliantly, and contract workers to have as great an experience as full-time employees have day-to-day.
