Three more logistics dot-coms have bitten the dust. The online startups ceased business last month, further fueling predictions of drastic consolidation among logistics dot-com companies.

Cash-flow woes resulted in the closure of two of the companies. GoCargo.com, the New York City-based ocean cargo auction site, was forced to shut down because of a bank foreclosure on a line of credit, says Bob Magown, formerly GoCargo's vice president of sales. According to Magown, the bank is currently trying to sell GoCargo's proprietary software.

Similarly, SupplyLinks said it would shut down after it couldn't secure additional investor support last month. Based in San Francisco, SupplyLinks was set up as a virtual third-party logistics company that helped shippers manage the logistics process and secure the best routes and rates for shipments. The company was headed by David Beatson, former head of Emery Worldwide and Circle International.

Application service provider NeoModal also closed its doors last month, when the rights to its technology were acquired by supply chain software vendor Descartes Systems of Waterloo, Ontario. Ironically, NeoModal last year purchased one of the first Internet shipping exchanges, eRateRequest, then quickly closed it down.

Jim Watkins, a former NeoModal executive who has joined Descartes, says the Canadian software vendor will merge NeoModal with software vendor E-Transport, which Descartes acquired last year, into a new business unit called Descartes Ocean. Watkins says that Descartes Ocean will offer transportation management tools for carrier selection, booking, and routing optimization for shippers and carriers.
