The story

Founded by Patricia House and Thomas Siebel in 1993.1

Siebel Systems, Inc. began with sales force automation software, then expanded into marketing and customer service applications, including CRM. From the time it was founded in 1993, the company grew quickly.

Benefiting from the explosive growth of the CRM market in the late 1990s, Siebel Systems was named the fastest growing company in the United States in 1999 by Fortune magazine.

Thomas Siebel, Pat House

Siebel's "first experience with sales technology was in the late 1980s, when he worked for Oracle." At the time, Siebel Systems co-founder Patricia House also was working for Oracle. Siebel left Oracle to try his hand at a startup. In 1992 House left Oracle and together they worked on what became Siebel Systems (in 1993).
