How it works

Our story



Client case study:

How Jeff Peterson used KDSPY as a narrator for Audible

"I used KDSPY to choose books that sold well in Kindle before I would narrate them for Audible. I get a percentage book sales, so it HAS to be selling or I waste my time. I could narrate 1,000 books easily and not sell 20 copies. It's only by choosing winners that I can make money with. I have authors now who come to me who I know are winning writers, but back in the day, your software was the only tool I had that steered me to projects that would sell and earn me royalties". – Jeff Peterson, Audible Narrator.
