SAP
Dietmar Hopp · 1972
SAP is the world's largest vendor of enterprise software. Founded in 1972 in Walldorf by Dietmar Hopp and four former IBM colleagues, it built its first product—the RF financial accounting system—in 1973 for Imperial Chemical Industries in Östringen. Its technical distinction was real-time operation via local electronic storage and a common logical database, eliminating overnight punch card processing. It restructured from GbR to GmbH (1981), to AG (late 1980s), to SE (2014). Hopp led SAP from 1988 to 2005 and retained ~10% equity.
