Sira is an AI-native HR platform purpose-built for hourly and deskless teams, positioning itself as an 'AI Native Rippling' for that workforce. It uses intelligent agents to automate time tracking, scheduling, payroll, and HR tasks, including geofenced automatic time tracking, AI-driven attendance and shift coverage, timesheet anomaly detection, and one-click payroll. The company was founded by Nathan Belaye, a former Intuit executive who led the QuickBooks Workforce app, and Antonio Chan. Sira was part of Y Combinator's Summer 2025 batch and raised a $3.4M seed round.
