As announced today, Clarus has extended its relationship with Microsoft to develop and market Clarus eMarket, one of the first digital marketplace frameworks for Windows 2000.

&uot;The support that we have received from our first Clarus eMarket launch customer and partners is evidence of the benefits they realize the ClarusDirect architecture and open trading network will provide in creating and launching new digital marketplaces,&uot; said Steve Jeffery, president and CEO of Clarus. &uot;We have eliminated the dependency on a trading network while providing comprehensive trading services that will deliver distinct go-to-market advantages.

&uot;By maximizing the combined leading-edge technologies that Clarus and Microsoft offer, the Clarus eMarket solution will enable small and medium-sized enterprises to capitalize on the business-to-business (B2B) e-commerce explosion just like the larger companies,&uot; said Matt Fanning, Vice President of Sales and Marketing for Comcast Commercial Online. &uot;This partnership also demonstrates the continuing commitment Comcast Commercial Online has in providing quality value-added broadband solutions to our Comcast Commercial Internet Service (CCIS) customers.&uot;
