July 31, 2007 ­– iCrossing, a closely held digital marketing company based in Scottsdale , Ariz., announced yesterday its acquisition of Web-development firm Proxicom. Terms of the deal weren’t disclosed.

 iCrossing, founded in 1998 as a search marketing agency, works with clients such as Travelocity, Coca-Cola, General Motors, and Office Depot. Proxicom builds web sites for companies including Toyota Motor, Chevron and DuPont. iCrossing plans to combine Proxicom’s Web-development skills with its own search-marketing background to help clients develop Web sites that can attract more people.

“Anybody can paint a pretty picture or build a pretty Web site… what we are talking about as a company is what we can perform through these pretty pictures,” says Jeffery Herzog, iCrossing’s founder and chief executive. The combined company will employ 550.

The news follows an announcement last week that iCrossing received a $62 million investment led by Goldman Sachs and Oak Investment Partners to fund the company’s acquisition and growth strategy.
