MINNEAPOLIS--(BUSINESS WIRE)--Sept. 22, 2000--Net Perceptions, Inc. (Nasdaq: NETP), a leader in precision marketing and personalization software, is the top-ranked fastest growing young hi-tech company in Minnesota, according to Deloitte & Touche. The Rising Star Award, presented last night, represents a new category in the 2000 Minnesota Technology Fast 50 awards program. Rankings for the new Rising Star category are based on revenue growth during the previous three-year period 1997 to 1999.

"This award recognizes the efforts of a great team of people from around the globe - not just Minnesota," said Steven Snyder, Net Perceptions president and CEO. "Generating this level of growth in such a short period of time symbolizes the commitment and talent of the people we have working for us."

Net Perceptions' increase in revenues of 4673 percent in the three-year period of 1997 through 1999 resulted in a #1 ranking overall in the Rising Star category for Minnesota. Each of the Rising Star winners had more than 2,000 percent growth. Other winners in the category were Digital River, a Net Perceptions partner, which had 2936 percent growth and Charter Solutions, Inc., which had 4108 percent growth for the last three years. The average increase in revenues among companies who made the Fast 50, the category for older, more established hi-tech firms, for this region was 842 percent, an increase over last year's average of 683 percent.

"We congratulate Net Perceptions for its tremendous achievement and success in a relatively short period of time," said Ron Hafner, Deloitte & Touche partner in charge of the Fast 50 for Minnesota. "The Rising Stars are emerging companies to watch. Companies like Net Perceptions are playing a starring role in developing the infrastructure in the new economy. We are happy to honor their achievement with this award."

To qualify for the Rising Star award, companies must have had revenues of at least $50,000 in 1997; be public or private companies headquartered in the region; and be "technology companies" defined as a company that produces technology, manufactures a technology product, is technologically intensive, uses technology in problem-solving, or devotes a high percentage of effort to research and development of technology. Criteria are the same for the Fast 50 category, with the exception that 1995 revenues must be at least $50,000.

Winners of the 21 regional Fast 50 programs in the United States are automatically entered in the Deloitte & Touche Technology Fast 500 program, which ranks the nation's top 500 fastest-growing technology companies.
