Former CTO of Echopass and Co-Founder of Contactual Brings Proven Track Record, Vision, and Industry Expertise to Lead Company's Large Engineering Team; Five9 Now the Largest On-Demand Telephony Development Team in the Industry With Recent Acquisition of Russian VoIP Development Company

PLEASANTON, Calif. -- Five9, Inc., the leading global provider of on-demand call center solutions, today announced it has named Jim Dvorkin as chief technology officer. In this position, Dvorkin will lead development, product management, network operations, and customer support efforts of Five9. This appointment comes on the heels of Five9's acquisition of Eco NN, a Russia-based company with 60 development staff focused on developing VoIP and call center applications.

"Jim's proven experience in developing top-tier engineering teams and bringing innovative call center solutions to market will help us continue our leadership in the on-demand call center market, and develop innovative new products," said Brian Silverman, Five9 president and CEO. "Our marketing and sales momentum is accelerating in the United States as well as internationally, and we welcome Jim's addition to the management team."

Prior to joining Five9, Dvorkin most recently headed up salesforce.com's call center initiative that resulted in that company's recent Winter '07 product announcements in this area. Previously he served as CTO for Echopass, an on-demand host of Genesys-based contact center solutions. He was also the founding CTO of White Pajama (now Contactual), an early provider of contact center solutions for small businesses. Earlier in his career, Dvorkin was CTO and co-founder of NextAge Technologies, a developer of workforce management solutions. Prior to that, he held various technical positions at Genesys, a pioneer in the field of computer telephony integration. He was a technical director and he managed the deployment of Genesys solutions for all four French telecommunications providers and many large financial institutions. Dvorkin holds a master's degree in Computer Science from the State University of Lithuania.

"Five9 is leading a fundamental change in the way companies build and deploy call centers," said Dvorkin. "This is an exciting time for Five9 as on-demand solutions are where the industry is headed. I look forward to bringing my vision and experience to extend our worldwide leadership in on-demand telephony. The acquisition of Eco NN and opening of the Five9 Russia office will accelerate our ability to bring exciting new products to market."

The acquisition of Eco NN was completed in September. All engineers at the company are now working on Five9's Virtual Call Center product and will continue to reside in the Five9 Russia office located in Nizhny Novgorod, 250 miles east of Moscow. The addition of this development team gives Five9 the largest engineering organization of any on-demand call center solution provider.
