I'm glad to hear you're going back and refocusing the original project. I have to admit that when I got to the "Iron Conversions" part of the blog post, I was flabbergasted that you'd pivot towards an aspect of the business that you were apparently not good at. What you said about Iron Conversions was vague enough to leave some doubt, but it sure read like "My product failed, partly because I can't convert customers to save my life. I know, I'll start a new business helping people with conversions!" Put this way, it sounds like a pretty delusional plan, unless you learned something magical about conversions that for unknown reasons you just don't feel like applying to your existing business. Hope that doesn't sound too harsh.
Not harsh at all! You're right, but in my defense "Iron Conversions" was just going to be a massive dunning email generator. It would have hooked into a user's Stripe account and responded to webhooks with A/B tested dunning emails. The onus would have been on the user to convert their trials.
Good luck on phase 2.
