Love the transparency and boldness. My personal opinion is that your service sounds too good to be true so it makes me hesitate trying it out as there is a time and emotional cost to trying it out.
So far, no conversions yet. I can only conclude that the current format is indeed not the right one. Trust in the service can indeed be a problematic one.
I'm going to individual approach now: Reach out to people on IndieHackers who wrote about their idea, and browse around here (although, I think people will be in a later stage).
I'll be sure to get back when I have an update! :)
