What do you like best?
inwinyo saves effort and time while delivering accurate information for likely prospects and contacts we need for our business objectives. It is a great first step towards an enhanced lead generation process. That said, you really need to be sure of who you want to find, rather than running a vague or generic search. The plus side of it, again, is that inwinyo helps you find your niche. That has been of immense help, personally.
What do you dislike?
There is nothing I dislike. The product only demands that I know who I want to search.
