Fluid Truck has filed for Chapter 11 bankruptcy protection after laying off 30% of its staff and experiencing significant financial losses. The company, known as the Zipcar of commercial vehicles, has also received a $7 million interim loan to facilitate its restructuring and potential sale. This decision follows the removal of its co-founders due to mismanagement and mounting debts, including $12 million owed to its Fluid Vehicle Investor Program members. A potential buyer, Kingbee Rentals, has emerged but lacks the funds to acquire all assets. The situation remains dire for unsecured creditors.
