MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--June 27, 2001

Industry's First Internet-Scale Event Routing Technology Enables

New Generation of Collaboration Solutions

KnowNow, Inc. (http://www.knownow.com/) today announced the industry's first application internetworking solutions that drive business across the Internet by seamlessly integrating information among Web Services, applications and end-users. Leveraging the latest advances in Internet-scale publish/subscribe event notification, the KnowNow product suite enables applications and users to easily exchange 'events' that initiate specific actions or responses from other applications or users in real-time.

Using KnowNow event routing technology, organizations that rely on up-to-the-minute data -- whether purchase orders, system monitoring, inventory reports, stock quotes, auction prices, sports scores or news -- can now publish and subscribe to specific events, and collaborate to make critical business decisions based on real-time information over the Internet.

Dain Ehring, chairman and founder of Dorado Corporation said, "KnowNow solutions allow us to connect the Dorado network with bank back office systems, and provide our customers with real-time account updates through rich, personalized interfaces."

Real-time enterprise realized through application internetworking

Fulfilling the need to drive business across the Internet, application internetworking enables companies to easily integrate with a large variety of applications, services and end users in real-time. Accessible to an established developer base, these Internet-scale solutions deliver reliable, secure, asynchronous and real-time integration in any environment.

According to the Gartner Group, more than 80 percent of the information between companies is exchanged via batch file transfer rather than real-time mechanisms. In many cases, the data is manually re-keyed. "The need for companies to integrate their value chains is tremendous -- and this is where KnowNow can help," added Bill Barhydt, chief executive officer of KnowNow. "The KnowNow approach to application integration is standards-based to enable rapid development of rich Web applications with client/server usability, as well as interconnect new Web services without costly development cycles."

Enterprise-quality, Internet-scale architecture

KnowNow's standards-based technology offers information routing/filtering with guaranteed delivery across the Internet. KnowNow solutions combine a proven event-driven communications model and existing industry practices with the scale of the Internet to increase productivity, reduce time to market, leverage existing IT resources and lower total cost of ownership. The following products are currently available for download at the KnowNow Developer Center (http://developer.knownow.com/):

-- KnowNow Event Router -- high-performance backbone of the KnowNow framework
that powers application internetworking with simple, easily managed, scalable
real-time publish/subscribe event notification across the Internet;

-- KnowNow Microservers -- lightweight, client-side code embedded into browsers
and applications that enables client/server-like communication, holding open
persistent HTTP/HTTPS connections between the KnowNow Event Router and the
application;

-- KnowNow JavaScript Microserver -- lightweight software that opens real-time,
interactive data channels between browsers and applications without downloaded
plug-ins, applets or controls.

Future products in development will include modules and components to manage industry-specific processes such as content filtering, data transformation, security and clustering.

Kleiner Perkins Caufield and Byers leads funding

KnowNow recently received financing from recognized venture capital firms, led by Kleiner Perkins Caufield and Byers and Palomar Ventures. Additionally, strategic corporate investors include senior executives at webMethods, TIBCO, Cisco, CommerceOne, Sun, CollabNet, Netscape and Excite.

"Technology tends to move in cycles -- from the personal computer to the Internet to advances in optical telecommunications -- and each cycle creates new industries," explained Kevin Compton, partner at Kleiner Perkins Caufield and Byers. "As software based on Internet technologies becomes pervasive, secure and real-time, another new industry will emerge. KnowNow is a true innovator and early leader in this new application internetworking industry."
