HR Tech News

Software now touches every part of how companies hire, pay, and manage people. This section gathers news on HR platforms, recruiting tools, payroll and benefits systems, and the growing use of AI in workforce decisions. It is aimed at HR professionals, founders, and anyone curious about the technology behind modern workplaces.

Coverage commonly includes funding and product news from HR software vendors, AI screening and interviewing tools entering the hiring process, and platforms that manage global payroll and contractor compliance. Studies and rules addressing bias in automated hiring decisions come up regularly as the technology spreads.
