About
Dayforce, Inc. (formerly Ceridian HCM Holding Inc.) is a Minneapolis, Minnesota-based human capital management (HCM) software company — publicly traded on the New York Stock Exchange (NYSE: DAY) as an S&P 500 Information Technology component — providing cloud-native payroll, workforce management, talent management, benefits administration, and HR analytics software through the Dayforce platform to approximately 6,700 customers and 6.3 million active users globally through approximately 8,600 employees. The company rebranded from Ceridian HCM to Dayforce, Inc. in January 2024, aligning the corporate name with its flagship Dayforce product to accelerate enterprise market positioning and reduce brand confusion between the parent company and product names. In fiscal year 2024, Dayforce reported revenues of approximately $1.73 billion (+14% year-over-year), with Dayforce recurring services revenue (SaaS subscription revenue from Dayforce HCM platform customers) growing 18% as the company continued converting Ceridian's legacy Powerpay and Bureau payroll customers to the cloud-native Dayforce platform. CEO David Ossip built the Dayforce platform from scratch after acquiring Dayforce (the workforce management product, originally a Canadian startup) for Ceridian in 2012 and deploying it as Ceridian's cloud HCM replacement for the legacy mainframe payroll system — making Dayforce a rare enterprise software success story of a mature payroll company successfully transitioning its entire business to a next-generation cloud platform rather than being displaced by cloud-native challengers.
