The issue is these startup listings are attracting founders and potential investors (and advertisers of course), just not sure if they are the place for your target audience.
Like if you are selling super-awesome soaps target house-wives, why are you seeking listing from crunchbase.com then.
While it's good to be enthusiastic it's pretty important to note that for the majority of startups these sites are a dangerous distraction that shouldn't be optimized for or influence your company / marketing / growth / sales funnel / etc.
