Here is NEGATIVE, but honest feedback from my first paid user.

To be honest, I am not sad about it and that user unsubscribed. He gave me much more - he tested it and found missing features, which I didn't find by myself and this is gold.

I want to say thank you, my first paid user and hopefully you will comeback.

In next post I will write what I implemented based on this review. Stay tuned and enjoy my journey with me!

[Leo Parker @tulexaicom]

After I got my first paid user, I wrote an email to that user to request feedback and asked what he/she doesn't like and want to improve.

The answer really surprised me! To be honest it was negative, but it was very useful and valuable.

See my email to first paid user on screenshot. Answer I will post later.

[Leo Parker @tulexaicom]

Wow! Dreams come true!
I got my first paid user, he subscribed on VIP plan! Thats amazing feeling, I am super happy. So I will keep pushing! 🚀🚀🚀

Next steps is to collect feedback from him, to understand if there is any blockers and downsides and how I can improve the app to make him super happy by using TulexAI.
