Ask HN: What are your problems with influencer marketing software right now?

[oemerax]

I want to understand the current problems/needs of companies which are searching for the right influencer.

What kind of solution is missing? What are companies such as Phlanx doing wrong?

For instance: I don't understand why you have to sign up first, before using the product. In some cases they want your credit card credientals which seems silly to me.
