What Kronos does
Kronos, founded in 1977, originally built its business on time-and-attendance tracking for enterprises and evolved into a leading workforce management (WFM) vendor. In 2020, Kronos merged with Ultimate Software to form UKG (Ultimate Kronos Group), backed by private equity sponsors Hellman & Friedman and GIC; the combined entity now operates under the UKG brand with Kronos retained as a product line for workforce management. The company is headquartered in Chelmsford/Lowell, Massachusetts, employs 5,001–10,000 people, and serves 80,000+ organizations across 150 countries, including 67% of the Fortune 1000.
Kronos/UKG's product portfolio spans an integrated HCM, workforce management, and payroll platform. Core offerings include UKG Pro (enterprise HCM), UKG Ready (SMB all-in-one HR/payroll), UKG Pro Workforce Management (the Kronos heritage product and Nucleus Research WFM Leader for seven consecutive years), UKG One View (global payroll consolidation), and the UKG Pro People Assist mobile experience. Underpinning these is Bryte AI, a people-first AI layer claimed to be powered by the largest collection of HR and workforce insights in the world, supporting natural language interactions, smart scheduling, predictive analytics, anomaly detection, autonomous agent guidance, and process automation across the platform. A UKG Developer Hub exposes APIs for third-party integrations, and the UKG Marketplace extends the platform via validated partner integrations.
Revenue is generated primarily through per-employee-per-month annual subscriptions across enterprise and SMB tiers, supplemented by managed payroll services and implementation/professional services. Go-to-market combines enterprise field sales targeting Fortune 1000 accounts, dedicated sales motions by business size, regional sales offices across the Americas, EMEA, and Asia-Pacific, and a partner ecosystem of implementation specialists and technology integrators. The company does not publicly disclose revenue or ARR.
