A working directory of the platforms that hire, pay, and manage the world's workforce — Workday, ADP, Greenhouse, Deel, Culture Amp and the wider HCM and talent bench — as AI takes over the resume screen, the interview slot, and the sentiment score that predicts who quits next. This is a first pass, built to be appended, not a finished census.
The function built to manage disruption for everyone else is now living through its own. Resume screening, interview scheduling, and candidate pre-qualification — once the bulk of a recruiting coordinator's week — are now standard AI features across the applicant-tracking stack, and Stanford's Digital Economy Lab, working from ADP payroll data covering millions of U.S. workers, finds employment for 22–25 year-olds in AI-exposed occupations down roughly 13% since late 2022, even as older workers in the same roles held steady. Challenger, Gray & Christmas reports AI was cited in 40% of all U.S. job cuts announced in May 2026 alone, up from just 7% in January — and Forrester's 2026 workforce predictions go further, warning HR teams themselves could see staffing cuts of up to 50% as executives test how far the efficiency promise can be pushed.
The people-analytics layer is moving the same direction. Platforms built to flag flight risk and engagement dips are now standard in Workday, Visier, and Microsoft Viva, positioned as tools that let a shrinking HR function watch a workforce it increasingly didn't hire. ADP research finds 48% of large businesses have already adopted agentic AI in HR workflows, with CHROs projecting 327% growth in agent adoption by 2027. The AI-Native Disruptors tier below tracks the challengers building recruiting, screening, and retention prediction as AI-first products rather than bolt-on features.
