This is great feedback, and I believe the solution is to be even more transparent. I was thinking of adding some FAQ after the pricing to give people some insight and increase the trust level.

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! :)
