Consonus Selects Siebel CRM OnDemand Over Salesforce.com to Drive Rapid Sales Growth; Server Hosting Provider Benefits From Integrated Sales and Marketing System as It Looks to Expand Throughout the Western Region.

SAN MATEO, Calif. -- Siebel Systems, Inc. (Nasdaq:SEBL), a leading provider of business applications software, today announced that Consonus, a provider of AllWaysOn Data Center Facilities, Business Continuity, and IT managed services, chose Siebel CRM OnDemand over Salesforce.com for its hosted CRM solution. Siebel CRM OnDemand allowed Consonus to drive sales through accurate forecasting and team collaboration between sales and marketing. The company chose Siebel CRM OnDemand for its ease of use, superior reputation, and rich feature set for sales pipeline management.

"As the premier data center provider for managed dedicated server hosting in the Rocky Mountains, we are looking to expand beyond our local region. This kind of growth could not be handled effectively without the comprehensive customer relationship management capabilities that Siebel CRM OnDemand provided. Salesforce.com didn't offer us the real-time analytics capabilities that have given us 24/7 visibility across our entire systems," said Daniel Milburn, Director, Sales and Operations at Consonus. "With Siebel CRM OnDemand we can tightly manage all areas of our company, regardless of location or time of day, something that is essential to our competitive value proposition of providing superior application support."

Headquartered in Salt Lake City, Utah, Consonus creates complete managed dedicated server hosting systems that deliver mission-critical business applications. A key market differentiator for Consonus is the company's ability to provide ongoing application support. Consonus database administration services reduce customer support burdens and requirements to hire and retain additional support staff. The company also presents software vendors with opportunities to host their application delivery, enabling them to expand their businesses through a broader client base. Consonus customers range from small businesses to Fortune 500 companies having one thing in common -- a critical need for 100 percent uptime with continuous and efficient support. The company has experienced rapid growth and is looking to expand throughout the Western region.

Senior management selected Siebel CRM OnDemand after an in-depth evaluation of available hosted solutions, including Salesforce.com. The Siebel CRM OnDemand subscription model supports Consonus' high-growth environment by delivering solid business results. The Siebel hosted solution lets the company deploy world-class customer relationship management (CRM) functionality quickly, with minimal up-front investment, while assuring security. With a pay-per-user approach, Consonus can expand the number of users as needed without costly hardware and software expenditures.

Consonus customers need continuous and efficient support. With Siebel CRM OnDemand, Consonus can track and service these customers and develop a deeper sense for their business requirements. As Consonus grows, it now has a better grip on its own sales processes with an easy method of recommending criteria for percentages on closure rates and pipeline modeling. Through the Siebel Sales Process Coach feature, Consonus can deploy a consistent sales methodology that mimics its best salespeople, anywhere in the country.

"Our sales force has to be very efficient in order for us to meet our growth goals," Milburn said. "This report will give us needed insight regarding the number and types of activities mapped against opportunities created. It will help us spot problems immediately -- not next week or the week after -- so we can take action and keep our salespeople focused on the right opportunities."
