The C in C/4HANA represents the customer, 4 stands for "4th generation CRM," and HANA refers to the SAP HANA in-memory database that C/4HANA runs on. The name also pairs C/4HANA with SAP S/4HANA as the core of the "intelligent enterprise." The release of C/4HANA culminates a process SAP undertook to enter the CRM market by acquisition, starting in 2013 when SAP acquired Hybris, a Germany-based enterprise CRM and marketing automation vendor. Other key acquisitions were Gigya, an identity management technology firm in 2017; Calliduscloud, a sales performance management tools vendor in 2018; and Coresystems, a field service management platform vendor in 2018. Last but not least Qualtrics in 2019.
