Hearsay Social is one of the newer social sales and marketing companies in the market, but that doesn’t mean the site hasn’t already claimed to have some explosive customer growth. The company just announced some executive moves designed to make the company that much stronger including bringing over a former founding executive of Google (News – Alert), Michael Lock. Lock will serve as Hearsay Social’s chief operating officer. The company also poached a former Microsoft vet in Mark Gilbert. Gilbert has been named as Hearsay’s vice president of product.
