I agree. The service is also very vague. Competitor analysis in what? SEO (ala SEMRush?), Competitor analysis in PPC? Competitor analysis in website audience(ala Quantcast?) Competitor analysis in the form of consulting?
it would mostly growth-related data-- you will get how the company has grown over the quarter in terms of users and revenue, what new marketing strategies they have undertaken, new products or features they have released, complaints current users are giving to them, and their overall strengths and weaknesses, as observed objectively by me. The point is to allow you "to keep an eye on your competitors" because most startups don't have the time to do so.
