About this site
Hi there! My name is Richard.
A little background. I spent four years growing my previous startup, Most Recommended Books, into the top book recommendation site.
We achieved that goal in July '23 with 750,000+ monthly visitors.
So I started looking for my next challenge...
In February '24, I finally found it! Build 25 AI Startups in 50 weeks.
So why Mental Math Pro? I built it a year ago because I love mental math (and did not like the existing tools).
Initially, it was unrelated to the AI challenge...
But in May, it started receiving 50 visitors a day (!!)
So I decided to spend 1-2 months taking everything I've learned from the AI challenge so far, and improve Mental Math Pro.
I hope you like the changes 🙂
P.S.: You can follow the AI challenge on X and Medium.
