Alterian, which provides marketers with a suite of content management and social media monitoring tools, has bought up Intrepid, a social media consulting firm. Alterian says it’s buying Intrepid—which has 40 employees—in order to provide a “packaged solution of social media analytics and market research capability to organizations who have neither the time or in-house expertise to understand what the social media world is saying about them and how to make best use of it in their businesses.”

This is fast-growing Alterian’s third acquisition in two years; it bought up online content manager Mediasurface two years ago and followed up that purchase by acquiring social media monitor Techrigy last summer.
