ModusLink Global Solutions, formerly CMGI Inc., is an American technology and venture capital company, headquartered in Waltham, Massachusetts. The company supplies a range of internet and communications services, mostly to computer companies, its biggest customer being Hewlett-Packard Company which accounts for 30% of their fiscal 2007 revenue. Its services include inventory and supply chain management, and software and services to support customer logistics, fulfillment, customer relations, and web-based retail. The company provides these services mainly through its subsidiary ModusLink Corporation.

The company was founded in 1986 as CMG Information Services, Inc. by David Wetherell, who was formerly the company's Chairman. The company's initial public offering was in 1994. CMGI's December 2006 market capitalization was $662.4 million. CMGI's stock boomed in the dot-com bubble of the late 1990s, peaking at $163 in 2000, for a market capitalization of more than $40 billion. The stock crashed heavily when the bubble burst, falling below $1 in 2002. As a result, the company was forced to cease its acquisition spree, sell many of its investments, and reduce other costs such as the naming rights to CMGI Field, home of the New England Patriots.
