When Freddie Mac acquired Tuttle Decision Systems from Microsoft’s HomeAdvisor Technologies, Inc., it left only one small piece behind for Microsoft to unload. Last week that piece, Tuttle Risk Management Services, Inc., announced that it has undergone a management buy-out and will operate as a stand-alone company. Back in the spring of 2000 when HTI acquired Tuttle, it was quickly separated into two distinct businesses, Tuttle Decision Systems and Tuttle Risk Management Services, or TRMS.
