It was called WeissComm Partners and founded by Jim Weiss. The firm was restructured and renamed WCG in 2009. In 2012, WCG became a company of the W2O holding group. W2O Group was founded as WeissComm Partners in 2001 by Jim Weiss as a one-person marketing consulting firm, with clients primarily in the healthcare industry. His firm grew quickly until 2008. According to Weiss, less favorable conditions in the healthcare industry led to a series of layoffs. In response, the following year Weiss acquired creative services firm ODA and social media marketing firm, Common Sense Media Group, in order to diversify his interests and reduce reliance on the healthcare industry. That same year, Weiss re-formed the company under the acronym WCG, consolidating the two acquisitions under a new corporate umbrella. The acquired companies and the firms revenues continued growing. By 2011 it had annual revenues of $48 million.
