Attributes its 307 Percent Revenue Growth Over Five Years to Strong Market Demand for Online Conversion Solutions

NEW YORK, NY - September 26, 2007 - LivePerson, Inc. (NASDAQ: LPSN), a provider of online conversion solutions, has been named to Deloitte's prestigious Technology Fast 50 Program for the New York Region, a ranking of the 50 fastest growing technology, media, telecommunications and life sciences companies in the area by Deloitte & Touche USA LLP, one of the nation's leading professional services organizations. Rankings are based on the percentage revenue growth over five years from 2002-2006.

LivePerson's chairman and CEO Robert LoCascio credits demand for Timpani™ Sales and Marketing, the company's flagship software platform that enables companies to proactively engage online visitors, for the company's 307 percent revenue growth from 2002-2006.

"Consumers are spending more time online every year and their expectations from the Web keep rising," said LivePerson CEO Robert LoCascio. "eCommerce continues to mature and LivePerson is committed to providing solutions that help our clients deliver a differentiated online experience, increasing sales, consumer satisfaction and brand loyalty."

LivePerson's increase in revenue of 307 percent from 2002 to 2006 resulted in a 37 ranking in the Technology Fast 50 for New York.

"Deloitte's New York Technology Fast 50 companies have shown the strength, vision and tenacity to succeed in today's very competitive technology environment," said Ed Moran, Director Product Innovation, Deloitte Services LP, New York. "We applaud the successes of LivePerson and acknowledge it as one of the very few to accomplish such a fast growth rate over the past five years."

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in 2002 and $5,000,000 in 2006, be headquartered in North America, and be a company that owns proprietary technology or proprietary intellectual property that contributes to a significant portion of the company's operating revenues; or devotes a significant proportion of revenues to the research and development of technology.
