Siebel Systems

Siebel Systems, Inc. was founded in 1993 by Thomas M. Siebel and Patricia House, both formerly of Oracle, to build sales-force-automation and customer relationship management (CRM) software for large organizations. The company grew rapidly through the late-1990s boom, was named the fastest-growing company in the U.S. by Fortune in 1999, and became the world's leading provider of eBusiness application software with more than 6,000 employees across over 100 offices in 30-plus countries. In September 2005, after years of rivalry with Oracle, Siebel Systems agreed to be acquired by Oracle Corporation, a deal that closed in January 2006, folding its CRM technology into what became Oracle Siebel CRM.
