Move, Inc., the operator of online real estate sites Move.com and Realtor.com, said today that it has acquired Threewide Corp., operator of ListHub, an online real estate syndication service for brokers, real estate franchises, and multiple listing services (MLSs). The deal was worth $13M in cash. Move--which has major operations in Westlake Village--said the acquisition will allow it to deliver greater value to its customers. ListHub syndicates 2.4 million property listings, from more than 270 MLS systems and 38,000 brokers, to more than 70 real estate marketing web sites. In additon to the acquisition, it appears that Move's center of gravity has shifted squarely north, to Campbell, California, where it now lists its headquarters. Move had formerly been based in Westlake, but has increasingly been hiring executives and employees from Silicon Valley.
