Earlier quoted context omitted.
I will not be providing proof here, but I went from someone who last wrote production code >15 years ago, to last week, a Fortune 50 demo client saying "this is far better than our internal tool." I am a solo builder. I feel like I am an outlier, but I do exist.
Did you make money from it?
The first client has paid, and signed a 3 year contract. Not huge money, but 5 figures per year. That client didn't even see what the F50 demo user saw.
