Gibu Thomas, CEO of Sharpcast, was surprised by the negative rating VC Ratings gave his company. After the company announced $13.5 million in second round funding from Sigma Partners, Draper Fisher Jurvetson, Selby Venture Partners, I questioned its ability to build barriers to entry and whether a startup will be able to capture the market they're going after.

Thomas does not lack ambition. And the product --which is being launched for the first time today-- is useful and easy to use. However, I still question whether Sharpcast will be able to be the company that can capitalize on people's desire to sync their mobile phone, desktop and web-based files.
