Knotch Adds Yahoo Veteran Ross Levinsohn to Board

Wall Street Journal: Marketers continue to pump more money into digital sponsored content. But many in the industry complain that there are few proven methods for gauging whether it actually works. That’s where the startup Knotch says it comes in. The company has just raised $4 million as it looks to build out a standard means of tracking the impact of content produced by, or for, advertisers. Among Knotch’s investors are Greylock, Allen & Co. and Stanford University. In addition, Ross Levinsohn, former CEO at Yahoo, has joined the company’s board.
