Shiftgig is an on-demand / "gig" labor platform that historically connected hourly workers ("Specialists") with short-term shifts (events, hospitality, retail, light industrial). Over time the company repositioned itself as a B2B workforce technology vendor and offers a SaaS platform called Deploy aimed at staffing agencies and organizations managing large pools of flexible workers. Deploy provides features for worker self-scheduling, matching, messaging, and marketplace-style shift claiming.
A key nuance: multiple sources indicate Shiftgig's public gig marketplace may no longer operate in the same way it did historically. The Shiftgig mobile application has, at least historically, become tied to staffing agencies that are "Powered by Shiftgig," rather than functioning as an open marketplace that any worker can join. (See "Known Issues & Limitations" for supporting evidence.)
