Siebel CRM Systems, Inc. was a software company principally engaged in the design, development, marketing, and support of Customer relationship management (CRM) applications—notably Siebel CRM.

The company was founded by Thomas Siebel and Patricia House in 1993. At first known mainly for its sales force automation products,[1] the company expanded into the broader CRM market.[2] By the late 1990s, Siebel Systems was the dominant CRM vendor, peaking at 45% market share in 2002.[3]

On September 12, 2005, Oracle announced it had agreed to buy Siebel Systems for $5.8 billion.[4] "Siebel" is now a brand name owned by Oracle Corporation.

The CRM software development environment is known as Siebel Tools and those skilled in such are known as Siebel Consultants.


Siebel Systems, Inc. began in 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[edit]

Siebel's "first experience with sales technology was in the late 1980s, when he worked for ... Oracle." At the time, Siebel Systems co-founder Pat House also was working for Oracle. Siebel left Oracle[5] to try his hand at a startup. In 1992 House left Oracle and together they worked on what became Siebel Systems (in 1993).

Programming Environment[edit]


Siebel Composer is a Web-enabled application that runs on a server, and you access it in a browser by using a Siebel Open UI client. Siebel Tools is a stand-alone application that runs on Microsoft Windows. In Siebel Composer, you can add fields to business components or applets, and you can designate objects as inactive or active. Oracle is gradually migrating from Siebel Tools to Siebel Composer to simplify and expedite the process of configuring Siebel Business Applications. In Siebel Composer, you currently have access to some of the functionality in Siebel Tools, so you can use Siebel Composer to perform some of the tasks that in the past you performed in Siebel Tools. Developers can review this guide to understand currently available functionality in this developing product.[6]

Programming Languages[edit]

You can use the following programming languages to access object interface methods and object interface events:[7]

  • Siebel VB (Siebel Visual Basic): A programming language that is syntactically and semantically compatible with Microsoft Visual Basic. It includes an editor, debugger, interpreter, and compiler. It runs only on the Windows operating system.
  • Siebel eScript: A programming language that is syntactically and semantically compatible with JavaScript. It uses the same tools that Siebel VB uses. Siebel eScript runs on the Windows and UNIX operating systems.

Server Script[edit]

A Server Script is a type of script that the Siebel Server interprets and runs. You can use the following scripting languages in a Server Script:[7]

  • Siebel VB: Siebel VB uses most of the same commands and standards as Microsoft Visual Basic, so you can customize your Siebel application and reduce training costs. Siebel CRM supports Siebel VB only on the Microsoft Windows operating system.
  • Siebel eScript: Siebel eScript uses most of the same commands and standards as JavaScript, so it provides you the same advantages in an alternative language. You can use Siebel eScript on all operating systems that Siebel CRM supports.
