 RecommendedPros: 

As someone historically on the business side, competitive analysis is a part of everyday life. This is a novel idea for making it easier.

Cons: 

Limited information for now, but I assume it will be come far more robust.

Everyone can go look at social following or hunt down some sort of financial metrics of a company in Crunchbase. Sifter gives some cool data that isn't super easy to find, like NPS, which is important to marketers.
