Oracle and Siebel—A Customer-Driven Combination


On September 12, Oracle announced its plan to buy Siebel, the leading provider of Customer Relationship Management (CRM) software. Oracle expects the transaction to close in early 2006, subject to regulatory and other approvals. Until the deal closes, each company will continue to operate independently.


Oracle President Charles Phillips and Siebel CEO George Shaheen detailed the benefits of Oracle’s proposed acquisition of Siebel Systems at yesterday afternoon’s town hall meeting at Oracle OpenWorld. Partners, customers, and user representatives joined the executives on stage to applaud the proposed combination of the enterprise software companies.


And they were not alone. Phillips recounted conversations he and Shaheen recently had with Oracle and Siebel customers about the prospects of the joined companies. He reported that customers are extremely pleased with the announcement. “They are saying ‘This makes a ton of sense. We were wondering what took so long!’” he recounted. “The feedback was very encouraging.”


International Oracle User Council executive John Matelski echoed Phillips’ findings, reporting that the PeopleSoft and JD Edwards customers Oracle acquired this year are very happy with the support they have received. “Siebel customers should expect the same,” he said. “They are going to have options.”


Phillips provided a summary of the customer benefits of the combination in a single statement. “The more smart people we have focused on CRM inside of Oracle, the better,” he said. “All of the products, even near term, start to benefit.”

Siebel provides best-in-class customer-facing products and industry solutions to more than 4,000 customers and close to 3.5 million end users, and Oracle plans to make the features of those products the centerpiece of its Project Fusion CRM products.
